How to properly call record id for Related action
Hello everyone, I’m new with Appian and I’m currently trying to work on a basic CRUD project.
I’m currently struggling to create an “Update” related action for my List.
1.- I have created a query expression rule to retrieve only the values of a specific record based on the id, which is currently working properly.
2.-I have created a related action inside my main Record Type to Update my record which has the following context for the process model parameter:
{
TSM_TaskList:
rule!TSM_queryTaskList(
tasklistIdPk: rv!identifier
).data
}
3.- I have edited the list to add a grid for the “Update” button next to the record, and I added the following display value:
a!recordActionField(
actions: a!recordActionItem(
action: recordtype!TSM_TaskList.action.updateTaskList,
identifier: fv!identifier
),
display: “ICON”
)
The button display successfully on the table for each record, however when I click on it, I get the following error:
“An error occurred while applying the context for the TSM Task List action [identifier=220,990]. Details: Expression evaluation error: TSM Task List can only be indexed into using square brackets or the index function”.
Can anyone help me identify where is my issue?
Or if you guys have a better approach on how to create a proper Update record action.
