How can I find out in Script if Write and Close button or Write Button pressed?
The case is that I have a dependent table on the object form which should be updated when the object is written. But if the form will be closed right after Write and Close this is not necessary and I would like to skip this update. How can I do that?

In this case you can delete default buttons and ad new ones (with new scripts)

Thank you, maxd!
I've added a save and refresh button.
It works, but if it is a common solution? Looks like I have to override the control bar buttons every time I just want to do this simple dirrefence.

Yes, it's a common solution
