Force readonly on cells depending on user's group

Hello,

Users found approvals complicated to use. So we are implementing a manuel worklfow in PBCS using a flag that can be 0/1 or 2.

We want to force readonly on forms depending on this flag and the group of the user who retrieves the form.

If the flag = 0: force readonly for all users

If the flag = 1: force readonly for users of group 1

If the flag = 2: force readonly for users of group 2

We tried to implement this via a groovy rule launched on form load

We managed to get the flag by using the DataGridDefinitionBuilder.
