Hello

I'm extending support module, and added new field - "Resolution Summary" which should be filled up by HelpDesk representative.

then i'm intercepting ticket close event and checking weather field is not empty, and if it is empty, im rising error, something like:

@api.multi
def write(self, vals):
    if 'stage' in vals:
        if vals['stage'] == 4:
            if not self.resolution_summary:
                raise osv.except_osv("Resolution Summary is Missing",
                                     "Please Enter Resolution Summary Before Closing Ticket") # *** Rest functionality is Skipped *** #

However instead of throwing exception with "Warning" pop-up, I would like to display proper pop-up with window name
and single filed "Resolution Summary" as text area

I'm fine with front end XML part, but very confused with - how to call pop-up from within a "write" method?
