Re-populating values in data block after commit

Question

I have a form with 2 tabs. The user can create an event in first tab and then associate/disassociate the event to data_points in the second tab (associate_event data block).
Say, I create an event, and query the records affected by the event in second tab, 5 records are retrieved. I press the associate_to_event push button and hit Save. All the 5 records get associated to the event, but as the associate_event data block is based off a view with instead-of triggers, I do not get any message saying 'these many rows were affected'.
I am OK with not getting the message, but atleast I should re-populate the values in that block so that the user can see that the changes were made.
So I created a key-commit trigger on the associate_event data block. The code in that trigger is as follows:
do_key(commit_form);
repopulate_values;
But my form is just sitting there (taking long to fiinish and hence timing out). Is there any other way of doing this?
(Also on another note, if I repopulate the associate_event datablock, the status of that block will be changed (as I am proceduraly assigning values to the block ) and then when user wants to exit the form, it will agaiin ask for 'Do you want to save the changed you made?' How do I avoid it?? Do I create a global variable and assign it some value say 1 when called from the key-commit trigger and check somewhere ?? if the value is '1' then dont pop-up that message )
Thanks in advance.

Thank you Magoo.
I am now able to re-populate the values. (The way my form was sitting there, made me that it was going in an infinite loop, but I could not point out what was causing that. Thanks!)
But my data-block associate_event retreives multiple records, therefore
"set_record_property ( :system.cursor_record, 'associate_event', status, query_status ); --> no ask for commit after repopulate_values ... "
does not work. And if I select Yes from the pop-up, I am getting the following error 'ORA-00933: SQL command not properly ended'. I checked the error and some how the update statement is incomplete. (This error does not/did not occur earlier when I just retrieve data. Remember, its coming from a view and the datablock is getting populated proceduraly, therefore everytime I wish to go out of the form, even after a retrieve , I get the message. (Which is fine with the customer.) So I dont get the 'ORA-00933: SQL command not properly ended' , when I press yes !! (But it tries to a insert and not an update at that time and I have a instead of update/insert trigger on the view).)
How do I get rid of the pop up, after the commit. I could not find any similar set_block_property :(.
Or should I suppress the pop-up in key_commit, or do another commit-form after repopulating data??
