Removing a confirmation pop-up after a button click

Question

What I am trying to do is the following:
I have a confirmation popup for a table row delete triggering action 'delete_confirm'.
yes action = 'delete'
no action = 'none'
If they choose yes (delete) the action handler calls the controller method which will call a back end service which takes care of the delete.
The problem I am encountering is that the dialog box will remain on the screen until the back end method call has finished processing.  I'd like to dismiss the dialog box immediately after th button push and display the standard WD hourglass + processing graphic while the back-end call processes.
I hope this is clear; if not, I will try to elaborate.

Answer 1

Thanks for the response.  You are right, I needed a second round trip to process both independently.  Unfortunately, I was unable to find a graceful solution.  Instead, I used the timer control and manipulated it in such a manner that it fires off an action 1 second after the window closes.  It's fairly transparent to the user and they get to see what they are used to in terms of loading so I'll just have to wait until enhancement pack 1 to do this a different way I think.
