Change to display field on control block not reflected until form refreshed

Question

Hi guys, hope someone out there can help me with this query.
I'm currently developing a form that will allow users to generate offer letters and contracts via a custom form which is used within Apps 11i. This form is a fairly standard multi-text field form with tickboxes which hold the applicant details, two buttons (one to Select All, the other to Clear All) and another button to produce the actual contracts selected.
There is also a display field which is part of the control block attached to the form; both it and the Produce Contracts button are part of this control block. I've added a bit of code to change the text in the display field to inform the user that the contract or contracts they've requested are being generated, but although the call to the relevant code to do this appears before kicking off the concurrent request to generate the contracts, the update to the field fails to appear until after the concurrent request is complete and its output appears on another screen.
Does anyone know why this is? I've racked my brains over it and can't seem to understand why. I've pasted the code in below if anyone has any ideas!
Many thanks, Geoff

I had a similar problem, but it was with the message line. I found that with Web Forms, I had to issue the Synchronize; a second time, but in Client/Server Forms 6i, the first synchronize worked. Here is the code I used:
<pre><font face = "Lucida Console, Courier New, Courier, Fixed" size = "1" color = "navy"> SYNCHRONIZE;
if Get_Application_Property(User_Interface) = 'WEB' then
synchronize;--first does not work on web
end if;</font></pre>
Let us know if this works.
