Subject Re: [Trinidad] Using window.opener with Dialog Framework
Date Mon, 15 Dec 2008 11:36:54 GMT
Hi Rafa,

Thanks for your reply. I'm aware of the returnListener attribute.

However, the way the application should work is to first confirm that
the document was printed successfully, and only then to proceed
processing. If not, to re-show the dialog for printing again. The
previous implementation did this via Javascript, by calling a function
on the opener window, which re-displays the printing/dialog window, or
goes back to the server to process.

I could call the process method in my backing bean in the
returnListener, however I first need confirmation that printing was
successful from the user before doing this. The way I was going to try
handle it is by having a 'close' button that's not displayed when the
media is print, that way the user will now have to click the 'close'
button instead of closing the window, which will confirm with the
user, then the returnListener can process and update components... I
think. Although then the problem still remains that on closing of the
dialog, the user isn't first asked for confirmation before processing
continues...

So instead I'm just doing away with the dialogs and navigating to the
print page, which just has buttons that aren't displayed when the
media is print.

Cheers,

James
