Store Inbound Email as Document in Appian Without Pulgin

ashwinir5622 — Mon, 18 May 2026 10:00:26 GMT

We have a process in our environment which gets triggered whenever it receives an email. We have a requirement from business where they want the whole outlook email or any email sent by them to Appian which triggers the process to be stored as some document inside Appian. Without any pulgin option is there any way to achieve this?

Reset value in datetimefield

josemanuc746243 — Thu, 14 May 2026 08:15:41 GMT

Is there any way to reset the value to null when only the date or time is entered in a datetimefield?

Screenshots attached

1. Enter only the date in 'Fecha entrega en mano'

2. Click on CANCELAR and confirm

3. Click on EDITAR again

4. As can be seen in the screenshot, the previously entered value is displayed by default. Appian does not reset the value to null for datetimefields. However, for fields other than datetimefields, it does reset them and previously entered values do not appear.

Issue with Browser Tab Title Displaying Process Name

glaralandin — Fri, 01 May 2026 07:25:17 GMT

Hi team!

I’m running into an issue with how navigation names appear in the browser tab—the tab is currently displaying the process name.

Has anyone dealt with this before? I came across some older posts (3–4 years ago) describing the same issue, but I’m wondering if there have been any updates or new approaches since then.

Any pointers or examples would be greatly appreciated. Thanks!

a!booleanCheckboxField() – choiceLabel alignment issue

Patrick Ludewig — Thu, 30 Apr 2026 08:00:17 GMT

I’m quite new to Appian and noticed an alignment issue within one of my interfaces. I wanted to ask whether this can be fixed or if it’s a known issue with this function.

The alignment between the text and the checkbox seems a little off (I’m seeing the same issue with a!toggleField() as well), and I haven’t been able to fix it myself.

Does anyone know of a workaround for this, or is this a known bug?

Tab refresh after update

likhithan — Mon, 27 Apr 2026 16:27:05 GMT

I have two tabs with insured 1 and insured 2 and if I am updating anything in insured 2 tab and clicking on save it is always coming to insured 1 tab since while updating we are using start process link and in the process model user input task is configured, so everytime it refreshes the page after the user input task was triggered, any way to solve this?The below higlighted are the 2 insured tabs and I am updating risk factor for insured 2 tab as soon as I update it is coming to insured 1 tab.

Checkbox Control in UI -- saveinto (NOT saveInto)

janakiramk524063 — Fri, 24 Apr 2026 15:07:19 GMT

Has anyone else noticed this in checkbox component. The expression mode does not show error when i have both saveinto and saveInto (notice the difference "i" vs "I"). I am able to save, and the selected value is not getting saved as expected. The expression mode does not show the parameter as invalid for "saveinto" and also does not save the value.

I always thought the correct syntax is saveInto with capitalized "I"

How to detect invalid input in a!dateField to disable a save button?

Miquel Lara — Wed, 22 Apr 2026 08:35:27 GMT

Hi Appian community,

I've been dealing with a tricky validation problem with a!dateField and I wanted to share it here in case anyone has found a workaround.

I have a form with several date fields that toggle between a!dateField (edit mode) and a!textField (read mode) based on a modify button that switches readOnly.Switching between these modes is done using a button in a separate rule; within that rule, I also have the option to save the data or exit edit mode. Once you enter edit mode, these two buttons appear. The save button is enabled or disabled based on the field validations.

When the user enters a future date, I can catch it with a custom validation rule and disable the save button without issues.

When the user types something completely invalid like "asdasdh" or "123abc" into the a!dateField, the native component validation fires correctly and shows the error message on the field — but Appian discards the value and stores null in the backing variable. Since null is also a valid state for my fields (the user may or may not fill them out), I have no way to distinguish between "field is empty" and "field has invalid input" to conditionally disable the save button.

the value "asdasdas" is saved as null in ri!valorReal.fechaPaso

I've tried to access the value of “123asbd” using `typeof()`, but the value of a valid date and any input are the same. I also tried to remove the letters using `regexreplaceall()`, but since the value stored by Appian is null, I can't access those values to validate them using `regexreplaceall()`.

The easy solution is to disallow null values, but that would break the functionality I need to implement, which allows the user to enter null values and displays a “-” as the default value in the text field.

Has anyone found a reliable way to detect invalid input specifically in a!dateField while still allowing null values, without replacing it with a a!textField (which loses the calendar picker)?

Appian display interface

daviddm-01 — Wed, 22 Apr 2026 07:38:29 GMT

Hi Community,

I’m working on a UI inspired by the attached mockup. I’m aware that Appian doesn’t natively support a fixed/sticky footer within an Overlay, nor a perfect 2x2 grid inside a standard buttonLayout.

However, I’m determined to get as close to this look as possible. Has anyone tried:

Using a columnsLayout with Cards as buttons to simulate the 2x2 grid?
Using a Header Content Layout inside the overlay to force the bottom bar to stay visible?

I'd love to hear any 'outside the box' ideas to bypass the standard layout constraints and achieve this specific action-bar aesthetic.

Appian split Button

daviddm-01 — Wed, 22 Apr 2026 07:29:37 GMT

Hi everyone,

I am looking to implement a Split Button functionality in my interface (a main action button with an attached dropdown for secondary actions). I am aware that this is not a native component in Appian's current UI toolkit.

Has anyone successfully implemented a similar pattern using a combination of a!buttonLayout() and a!dropdown() or perhaps a custom SAIL configuration?

I’ve considered using a small icon button next to the main button to trigger a menu, but I’m concerned about the alignment and the mobile responsiveness. If you have any examples or best practices on how to achieve this "split" look while maintaining a clean UX, I would greatly appreciate your insights.

Thanks in advance!

Problem with 'isButtonFooterFixed' parameter

Andres Gonzalez — Tue, 21 Apr 2026 15:11:19 GMT

I'm geting a problem when using the isButtonFooterFixed paramter in a FormLayout and opening it in a dialog box.

The interface preview is working as expected, when opening the process in a 'NEW_PAGE' is working as expected but if I try to open the interface as a Dialog box it is not fixing the buttons in the bottom part of the modal.

Anyone geting the same issue or knows how to fix it?

Thank you!

Problem with Button Footer Fixed in dialog

Andres Gonzalez — Tue, 21 Apr 2026 14:47:14 GMT

I'm getting a problem with the 'isButtonFooterFixed' parameter in formLayout.

I'm not able to get the behaviour expected when the interface is opened in a dialog.

If i open another action with exactly the same configuation but in a New page instead of in a dialog box, it is working fine.

Do I need to configure something else or is it just a behaviour that is not possible to achieve in Appian?

Thank you!

Image is not rendering in billboardLayout

kl0001 — Wed, 15 Apr 2026 20:49:06 GMT

I'm running through the spaceX integration demo as practice, and when the step got to the end and I'm supposed to upload an image to the billboard layout, but it didn't render. The document is jpg file, and it does end up rendering in the a!imageField (only when it's set to size = FIT) as you can see in the corner there. I can get other jpgs to render, but not this one. I'm wondering if it might be because it's too big (size = 20.12kb) or because it downloaded as a web file and I had to manually change extension to jpg (but it loads fine in the file preview when I click on the doc).

Anyone know why it might not be rendering? Thank you!

Unable to take properties into a forEach() for a fv!item

francescagulinelli — Wed, 15 Apr 2026 09:56:59 GMT

I'm having some issues understanding how to use indexes into a forEach taking the items from a expression rule.

I'll explain my problem a little bit deeper; I'm trying to get some of the properties from the RecordType "Anomalie", i would like to use the expression rule with get me all of the anomalies linked to a specific pension by the pensionid, and get the description, the name, the action related to it. But i'm having trubles indexing these properties once I call the expression rule. When I try to use fv!item.description into the description rich text field it seems like it doesn't recognize the object as a record type.

I pasted the code snippet for the forEach i have in the interface, does anyone had some similar issues and may give me suggestions on what to try to make it work? Thank you so much!!

(my finished product should be a card for each anomaly found linked to the record Beneficiary, each with their description, name and related action)

a!forEach(items: rule!SRI_AnomaliePensione(pensioneId: ri!record['recordType!SRI beneficiario.relationships.pensione.fields.chiavePensioneCorrente']),
expression: a!cardLayout(
contents: {
a!richTextDisplayField(
labelPosition: "COLLAPSED",
value: {
a!richTextItem(text: { "Anomalia" }, style: { "STRONG" })
}
),
a!richTextDisplayField(
labelPosition: "COLLAPSED",

),

a!sideBySideLayout(

views and action security refresh

saisaran31 — Wed, 08 Apr 2026 21:11:22 GMT

Hello Everyone,

In my record view interface, I have a child interface that contains a related action. I recently added another related action whose only purpose is to refresh the data. In the parent interface, I’m using a!refreshVariable() so that local variables are refreshed after a record action completes.

The related action in the child interface has visibility logic defined both:

in the record type (Views and Actions → action security/visibility), and
inside the child interface itself.
When I click my refresh-related action, all the data and components in the interface are refreshed, but the visibility condition defined in Views and Actions is not re-evaluated. As a result, when I refresh to load the latest data, the related action does not appear on the screen unless I do a full browser refresh.

i tried to have a start form in my related action's process model even at that time screen was not refreshed. Pretty much tried everything still record level security was not evaluated without manual browser refresh

Appian Grid

Gaurav Kataria — Tue, 07 Apr 2026 05:07:52 GMT

We are encountering the following error in our Appian application:

ERROR com.appiancorp.record.service.visitor.DiscoverAllRecordBindings - 
Exception encountered in grid field tree visitor, falling back in try catch.
java.lang.NullPointerException

This issue appears while working with a grid component (record-based or interface grid). There are no obvious breaking changes, but the error is being logged intermittently.

We suspect it may be related to:

Null values in grid field bindings
Record type relationships
Nested field references in grid columns

However, we are unable to pinpoint the exact cause.

What typically causes this DiscoverAllRecordBindings NullPointerException?
Are there recommended best practices to avoid this issue in grid configurations?
How can we effectively debug which field or binding is causing the problem?

Any guidance or suggestions would be greatly appreciated!

Loading one interface immediately after another

Vladislav Morozov — Wed, 01 Apr 2026 10:45:21 GMT

Consider blue path only! I used activity chain to start "Choose policy" interface immediately after the main interface. The process is started by a startProcess inside a saveinto of a buttonWidget. After clicking the button the process starts, but the interface isn't automatically loaded. The owner of the task is set as pp!initiator. What could I miss?

Re-ordering dynamic list

Guy — Mon, 30 Mar 2026 12:08:40 GMT

We have a dynamic array containing lists of data. Dynamic here meaning data1, data2..etc could be any length.

We need a screen that allows users to reorder this data and we are attempting to do this with a gridLayout with allowRowReordering = true.

When attempting this example below, we are seeing the error Expression evaluation error at function a!gridLayout [line 15]: A grid layout component [label="data1"] has an invalid value for "rowOrderData". The value must be a list of records, a list of maps, or a list of dictionaries.

a!localVariables(
  local!map: { "data1", "data2" },
  local!data: {
    data1: {
      { sortOrder: 1, label: "A" },
      { sortOrder: 2, label: "B" }
    },
    data2: {
      { sortOrder: 1, label: "C" },
      { sortOrder: 2, label: "D" }
    }
  },

How to Make Stacked Column Chart with Multiple Series?

dcao — Thu, 19 Mar 2026 16:34:28 GMT

Hi Appian Community!

I have a requirement where in the column chart below, I need to show a breakdown of the data for each bar of all the series based on the date.

I had to manipulate the dataset so using a record type was not possible. Now I have my data structured where x-axis is dates, and y-axis is the percentage of each area of the office's seat booking. How do I show within each bar, a breakdown of say half is booking type A and the other half is booking type B?

How to implement a PickerField with 15,000 rows that searches after 3 characters using Record Type?

Rishu Kumar Gupta — Tue, 17 Mar 2026 11:56:40 GMT

Hi Appian Community,

I'm working on a PickerField component that needs to display data from a large dataset (~15,000 rows). Here are my requirements:

Requirements:

Display a PickerField with approximately 15,000 rows of data
Implement a search functionality that only triggers after the user enters 3 or more characters
Load the data using a Record Type as the data source
Optimize performance to handle the large dataset efficiently

Current Challenge: I want to avoid loading all 15,000 rows upfront for performance reasons. Instead, I'd like the search to execute only when the user has typed at least 3 characters, and then load the filtered results from the Record Type.

Rule Input passing issue.

nishika_bade — Wed, 11 Mar 2026 14:16:47 GMT

There is an Interface C which has parent as B and B has parent as A. Now I am passing via rule input from C it is working in B but not in A.

The value gets refreshed at A interface automatically.

FYI the rule input data types are same for all 3 interfaces A, B and C.
