WBSGantt - what workflow is used when creating sub-task via the +Add button ?

[dada_rara]

i have a basic JIRA workflow configured with a post function that copies a custom field from parent when creating a sub-task.  this works while working outside WBSGantt.

but when creating a sub-Task from within the addon by choosing the +Add/ subtask

it does not !!!

whats the issue? how to change it?

Dear dada-san,

Do you use Automation for Jira to copy custom fields?
If so, could you change to "Trigger Issue"  on  "Issue to copy value from" of Then?
