I want to know the internal mechanism of local variable refreshing in an interface. When a local variable is refreshing, what is the underlying logic of the behavior? Is all code re-executed? Can you give me a conclusion and provide a demo to prove the conclusion.

I have a group, group type is business group, now I no longer need this group. How can I deprecate/remove it. It has been deployed to higher env like prod. I need to remove it from all env

Hi, I need to have a document upload form like this package import form, and have a validate button like inspect button, but I need to disable the import button before the document is validated successfully. I need to validate the document's content and format, so it's not just a validation for the size and type How can I do?

am getting this warning

Hi, sometimes I have to go back to the basic rules of Appian. I have an editable grid with REQUIRED fields to show in a page of a Site. To make this validation work, I have to put the interface in a start form of a process and then add this process in a site page as Action, otherwise it won't work. Is that correct? Thank you

Everytime that I try to open links for learning paths and courses in Appian I need to login (which I already did) and when I put my credentials, I see this error message:

Hello, I have a process for parsing data, and in one of the nodes, I'm checking whether the respective alert exists for a specific event. The script task has one output, which uses a QR rule to retrieve the alert based on the event's alert ID. The retrieved alert is then stored in another variable. The QR rule returns a single alert, which works as expected in all other environments, but in production, the result is null in the process model. This issue has also occurred with other processes using the same rule and having multiple outputs, but when we split the logic into two subtasks, it worked fine. However, for this process, the problem persists. Could you suggest what might be causing this issue?

I am creating a practice application that takes in a pet's owner, and the pets that the owner has. Because the owner can have more than one pet, I have created an editable grid that passes the input pets in to a rule input that stores them as a "list of recordType!w0428pv pet". I would like to be able to use the write records smart service to take that list and input it in to the database as individual records but I'm not sure if that is possible or the right way to go about doing this. I believe the process variable is storing the array of pets correctly, as it looks correct in the preview on the design page. Any advice would be greatly appreciated! 

Hi everyone, I hope you can help me with something that is driving me crazy. For some scenarios it works and for others it doesn't, but basically I have an interface where the only thing I do is show database information. I went from validating nulls in the following way, {} then to "" and finally null() but the error was always the same "Null? list must be used within a SAIL component" I attach an example of my code, I hope you can help me identify what the problem is. a!localVariables( local!newComment, local!dataVerification: if( a!isNullOrEmpty( ri!recordRequest['recordType!{f3693eb2-ffb2-4407-814e-681b44ba8ef5}TTC Request.relationships.{42fd7ed7-d716-49c6-b449-e1fa839b532a}client.fields.{82090d2d-4f09-4af2-9995-eda5781d1392}id'] ), "", rule!TTC_getVerificationByIdClient( idClient: ri!recordRequest['recordType!{f3693eb2-ffb2-4407-814e-681b44ba8ef5}TTC Request.relationships.{42fd7ed7-d716-49c6-b449-e1fa839b532a}client.fields.

hi  i would like to know if there is anyway to stop the scheduled process model during deployment

Hello, We have been using the PDF Doc From Template Smart Service for around 6 months now to generate dynamic documents. We create the templates using Adobe Acrobat Pro. All of the sudden, any file created in Adobe is outputting a <1kb file when using the SS. I have done troubleshooting all the way down to simply creating a blank PDF, saving, then running through the SS and I get the same result every time. I have tried multiple configurations using Save As > Optimized PDF with the same result as well. Can anyone shed some light on what my issue may be or provide some extra troubleshooting I can perform?

Hi All, Using Document Viewer I am able to view the regular PDF. One of my client requirement is they wanted to view the PDF Portfolio document through Appian. Is this possible in Appian? Can you guide me through this? Thanks in advance!

Hi Team, We have a requirement to build centralized Notification Management System. The system should support previews for all supported channels, such as email, SMS, push notifications, and in-app alerts. Appreciate your valuable input.  Thanks, Sinushree

Hi Team, The custom sender email functionality was working fine until last day in the environment. Suddenly it had stopped working and the send email node is getting errored, and error message says, "Failed to send email". Have anyone faced a similar issue, we have also observed that all the other mail functionality like process model is working fine. Please help us on this issue. Thanks.

Hi  I have a parent process which is deciding startDateTime and  delayMinutes and then passing this parameter to start process smart node which is delaying the subprocess with this set up: pv!startDateTime + intervalds(0,pv!delayMinutes,0) . However, this should delay the process by calculated time. But it is not delaying it at all.  I want to ask,  How to implement Dynamic delay in timer? Does intervalds does not work with process variables as parameters?

I am executing a process model from an interface on button click using a!startProcess, and saving some of the process variables (lists) on the OnSuccess parameter of a!startProcess into UI variables. The process model has chaining enabled on all connections, both in the parent process and two sub-processes.  Both sub processes run synchronously, and execute at the same time.  In both sub processes, I loop over an integration using a counter variable (not MNI). The issue that I am seeing is that the saves on the OnSuccess parameter of a!startProcess execute before the process is complete, so I either get no results from the process at all, or partial lists.  When I monitor the process, it executes successfully and all the expected values are there. How can I ensure that the entire process executes before the OnSuccess saves execute?   The process typically takes between 1-3 minutes to finish.   Note: The goal of this process is

In my use case, A Customer is linked to multiple Units in a one-to-many relationship. On one interface, I have a customer selection, and based on the selected customer, the corresponding units are displayed in a dropdown labeled "Unit." This is achieved using an expression rule within a refresh variable. Additionally, there's an option for the user to add a unit on the same page for the selected customer. For this, I'm using a Record action, where a pop-up window opens for data entry. Once the user submits the data, the unit list in the dropdown is refreshed to include the newly added unit. This is done using the "refresh after record action" feature. While this functionality works as expected in the browser, it does not work on the Appian mobile application. Any suggestions?Here is the Code Snippet local!units: a!refreshVariable( value: rule!FAA_QR_get_Unit( customerTpi: ri!assetRecord['recordType!{20d559ec-3d4b-4870-9672-f594295b09f7}FFA Asset.fields.

Dear community, Modal popup windows are a very frequently asked UI element Appian does not provide OOTB. The purpose of a popup is to make any UI element fade into the background and provide an isolated area to require a specific input from the user. In Appian, we cannot implement this visual style directly, but we can achieve a very similar behavior. Instead, we hide all UI elements and display a single centered card layout. This card contains all the necessary elements. When a user clicks a button, the popup is closed, and the rest of the UI becomes visible again. Read my blog post for more details. https://appian.rocks/2023/06/20/popup-windows-in-appian/ Cheers, Stefan.

why there is no user context in an expression in a node output

I would like to force logout a user without user interaction. I know that Appian has Session timeout, but I would like to logout a user on a specific workflow (after 30 sec) without disturbing Appian default session timeout settings.
