I'm experiencing some troubles trying to perform a custom validation in a XDP form.
I've the following scenario:
- I created an XDP form used for a Human Task in a process.
- The form receive a list of Items, that are listed in a table.
- The user MUST choose an item from the table before complete the task and continue with the process.
I successful created the table that list items, with a checkbox in the first column to select them, but I can't figure out where I can check, with a custom validation script, that the user has selected at least an item when he try to complete the task. Someone could help me?
