I think you need to fork a new (background) process in order to
have it run independently of the Ajax callbacks. The Ajax
callbacks will be executed one after the other, there will never
be any progress reporting.<br>
<br>
So I THINK what you absolutely have to do is to start the long
running Ajax callback as another process. <br>
<br>
So start by putting your sequence of process steps in a <br>
<br>
[ <br>
] fork.<br>
<br>
block and see if it improves things.<br>
<br>
<br>
I am using an inst var of the component instead of the session,
but I guess that doesn't really matter. Using the session is
probably a much better idea because you could then use this
facility for a general solution that works for all ajax callbacks
that run longer...<br>

</div>
<div>thanks a lot! I think I am very near to the solution but
there is one problem remaining: within the Ajax block, the
JQLoad seems to be "blocked". I explain:</div>

initialized with an empty string.<br>
