<br><font size=2 face="Arial">Hi Jocelyn,</font>
<br><font size=2 face="Arial">That was quite useful but I did notice that
when a workitem was executed the event STATE_CHG was published twice. I
wonder whether this is because it occurs when you first reserve the workitem
during execution and then again when you complete execution. No problem
for my application but maybe an issue if you only want to react once during
the LUW. </font>

be usable when the work item is forwarded, reserved or replaced. <br>

Hi Kjetil,<br>
<br>
Doesn't address the question whether it gets called during forwarding,
but<br>
a much more useful piece of info instead, thanks!<br>
