Hi Stefan,

I want to use a link in the below read only grid interface to edit the entries in another form. So calling another form when the user selects location name.

Below is the form to edit the selected entry.

I want to use a local variable that hides the grid and shows the selected location and do the necessary changes.

I tried with Process link but coming with a blank edit form. So thought of doing with a dynamic link.

But not able to figure it.

a!gridColumn(
          label: "Location Name",
          sortField: "description",
          value: a!linkField(
            links: {
              a!dynamicLink(
                label: fv!row.description,
                value: fv!row.description
              ),
              
            }
          ),
          align: "CENTER",
          width: "MEDIUM"
        )

Please advice.

Thanks

Something wrong with the way I was passing the parameters. Trying with dynamic link now.

Thanks

For the record action, you can only pass in the ID for that record. In your case, using location ID should be all you need because then you can query additional information on the form itself

You did it the right way. Have a process variable configured as parameter and pass the value in a dictionary.

What exactly did not work?

Hi,

I fixed the record action problem.

But I still want to know how to pass process parameters in process link in an interface in my case?

Thanks

Hi Danny,

Thank you for your inputs. I haven't marked Location Id as a parameter. I have location parameter of CDT type and cancel as parameters.

I tried using the record action but not able to pull in the action in my interface. I manually typed the name manageLocations.

I am getting the error: Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!recordActionField [line 4]: Invalid index: Cannot index property 'actions' of type Text into type RecordType

a!recordActionField(
      actions:{
        a!recordActionItem(
          action: 'recordType!{853ab9ac-cf5f-4aa8-950b-97bb7de9adab}BC Location'.actions.manageLocations
        ),
        
      },
      
    )

Also, you mean to say that I should add the below form as start form? or the add/edit form as start form? Please clarify.

Thanks

Ok. Thanks

Not sure. Depends on what you want to do.

Keep in mind that the data must match. The process variable is of a CDT type and the data passed in is just an ID. That will not work.

Hi Stefan,

Should I use both the below parameters in the process link? (processParameters: { locationId: fv!row.locationId })

Thanks

Have you marked the variable 'locationId' as a parameter?

Also, for your use case I recommend looking into record actions https://docs.appian.com/suite/help/20.3/Record_Action_Component.html

It's a much better design pattern and allows your uses to open forms in dialogs instead of a new page.

Also, I recommend setting your form as a Start Form

Define the process variables in the model as parameters. Check process model properties to do so.
