error redirecting in popup edit

This is correct, you cannot redirect from the popup window.
Once you click 'Save' window closes itself.

it works as you said, but if I add a redirect in the after edit event the window does not close, and the page does not redirect, but the record is edited. any solution?

thank you

The solution is to remove redirect. I'm not sure why you need it. Probably you need to provide more details on your setup.

I need to redirect to a page that prints a pdf document of the edited record and updates an other DB, then return to the list page. I cannot use server.execute (that will probably work correctly)

I see what you saying.
Unfortunately you cannot redirect user after doing edit in popup.
