Hi Appian Devs,I have long length dropdowns in the interface belowPlease let me know what is the probable reason of this error on the interface.Thanks in advance

Hi!, I´m having this error: The save target must be a local variable that does not refresh on every evaluation or on an interval, a process variable, or a node input (or a rule input passed one of those three) I´m trying to start a process with start form interface in a  a!startprocesslink inside a button. Any posible answers? Thanks

Hi all, My question is: What kind of field would you use in an Appian interface to display [but not allow editing] of a field like "created by" and "created date" that you want to display but not allow user editing - such that the data from these fields is actually stored into the database. Details of issue: My colleague and I are fairly new to appian development and are working on a problem. She created an interface that that allows us to add and edit the rows in a particular reference table. The interfae [mostly] works - in that it allows you to add and edit rows in the database table. The problem we have however is that there are some fields, which are not supposed to be directly edited by users. For example: "Created by""Created date" Rather than the users adding values for these fields, we want them to be automatically set by the system by retrieving the currently logged in user and the system date. My colleague has been able to set the fiel

So I am working on filling up my information in an interface that later will be saved and it will turn that interface into a read-only interface so I can see all my user information. The issue is that once I press submit, the interface doesn't update the fields from each section of the interface until I press refresh on my browser, is there a way to update those fields when I change it into read-only or make the site or page refresh?

Im new to Appian, first step i want to create in my app is a login page, can anyone help me on this Help me to create a simple login page with user authorisation, error message if wrong user id and password or if user id is not created in the app.

Hi Appian DevsI have a situation here to explain, please look at the two interfaces below:Interface 1: Add new templateWe can add new template here,I have to validate my text field which is "Template Name". In this, I have called a expression rule where the name of all templates is being fetched from the database. And then, I am able to validate it by checking if the text filed value input by the user does not already exists in the database or not. Case 1: Add New Template: The validation is working fine for the new addition of template.Case 2: Edit Template from template dashboard: In case of edit, the value of the text field is coming pre filled from the rule input. So, even if I change it to a new value, I am not able to validate it for already existing templates using the expression rule.Can you please suggest me a method to streamline the edit case.

Can we assign a task to a group or to a particular member through interface without using the process model??

Hello people! I hope you're doing well. Is there any way, video or documentation, where I can learn how to create a login page for my Appian ACME (Community version) Site?  For example, there is my site link like this:  But looks like an Appian login, not the ACME or my site custom login page.  Question 2, this means that if I create a user in my Appian ACME site that user will be allowed to access to the ACME Site? Thanks in advance! have an excellent day.

Hi readers, I would like to know if this is possible, i have a interface where it has a drop down which should have list of values from record types. example:  In the below table when entering data into Table-A it would be in a normal way; But when entering data into Table-B we need to enter ID_A as well right, So i am thinking to keep a dropdown in this place, where i can keep the list values present in  ID_A Table-A Table-A is as below ID_A(PK) Job_Role Company_Name 1 DBA ABC.ltd 2 SysAdmin ABC.ltd 3 HR ABC.ltd Table - B is as below Member_ID Name Phone_Number ID_A(FK) 1 SSR 1234567890 1 2 RC 0987654321 1 3 NTR 6789054321 2 4 RRR 1234567098 2 5 MB 0984562348 3

Hi, I am trying to use startProcessLink in a grid view Interface so that an user can edit the selected record by selecting a location Name. This is my first time using this method.  When I am selecting an entry, I am getting an error message:  An Error Has Occurred No process parameter found corresponding to override [name=pv!locationId]. Non-parameter process variables cannot be overridden. a!gridColumn( label: "Location Name", sortField: "description", value: a!linkField( links: { a!startProcessLink( label: fv!row.description, processModel: cons!BC_PM_ADD_LOCATION, processParameters: { locationId: fv!row.locationId } ) } ), My process model is working fine. So how and where do I fix it?  Please advice me.  Thanks

Hi Appian Team, We have a functionality to save the data from the interface to the database where we are not submitting it to the parent table, but a temporary table or cdt and use the same process model as the submit and add the nodes for temporarily saving feature like save as draft. Basically customized "Save as draft functionality". Can anyone help us to implement this functionality , if you have come across similar features in any of your application. Thanks Sunu Sam

How can I assign a default value to a radio button and make sure that value is saved even if the user doesn't interact with a radio button component? for instance, if I have local!radioButtonDefaultValue: false I see that the No label is selected, when value field of the component is set to local!radioButtonDefaultValue but the value itself isn't saved automatically unless the user interacts with the radio button component. I want to save the false value even if there is no interaction with the component.

Prereq: Site, tested in Chrome and Edge. My use case starts in a site as the main user landing point. From here various actions and a pair of reports are presented to the user. Depending on the user's screen resolution the initial landing page may or may not scroll. Given the user has scrolled down the page, when they click on a task link (from a task report for example) the task opens up within the site framework but is not at the top of the task, instead, the interface retains the previous scrolled to position. This has been observed where the target form has been constructed in either formLayout or in headerContentLayout constructs. I cannot find a way to force the vertical page position back to the top of the form. Can anyone suggest a solution?

Hi All, We have data stored in our DB in text format. But data added can either be text or json. We would need to display the same in the interface in proper format. That is if data is in plain text we would show it as text and if it is in JSON, we would need to format it and show. For eg : if data is stored as "XYZ" then we would show either in Rich text editor/text field as XYZ. If data is stored as text (in actual it is a JSON) -  {"Field1":"Test","Field2":"value is "not editable" test it.","Field3":"314146282515","Timestamp":"2019-06-19T11:05:23.678+0000","Field4":"XYZ","Reason":"XYZ","Time":"2022-02-19T05:09:26.046+0000","Field5":"ABC","Field6":"yui","Value":"OK","Action":"","Field7":"[abcged]","Field8":"&

Hi there, I have created two interface which are MedicalRequestForm and EquipmentRequestForm, then I created third interface as RequestForm where I took a radio button and shown the value as RequesType (Medical and Equipment). I want that MedicalRequestForm or EquipmentRequestForm must be shown on the basis of radio button selection which is working. But In my first both interfaces, I have one dropdown, so whenever I am selecting a value from the dropdown, then whole Interface (RequestForm) is getting reload/refresh. Note: I took the rule input as ZMS_Requests in all the interfaces separately. Please see the below screenshots: 1. MedicalRequestForm: 2. EquipmentRequestForm: 3. RequestForm (without selection): 4. RequestForm (with selection of Medical): 5. RequestForm is getting back as screenshot no.3 when I select a value from dropdown Animal Name as above screenshot. Could anyone of you help me to resolve this issue? Please let me know if you need code.

Is there any function from which we can count no. of rows present in read only Grid??
