Here is a snipper of my behaviors mostly using this function:
getFieldByName('a').setFormValue(b)
Which I guess explains why the field 'a' changes its value only when editing the form, it's in the name - setFormValue.
Is there any way to trigger the behavior and update the issues without going over and triggering them manually for the old issues? I am currently sitting on a lot of imported issues that were unaffected by the behavior. Any ideas?
