I found the problem – I attached
some _javascript_ on the onclick attribute with the commandLink that does the
submission. The _javascript_ caused double submit(). So there was indeed two
parallel executions at the same time. It seems that both submit() run on the
same thread (with the same HibernateFilter etc). That is very strange –
as I would have thought that the second submit() should at least execute on a
different thread. Regards, Yee From: Yee CN [mailto: Sorry, the last one was a bit grabbled. I
also just noticed that it seems that there are two parallel execution happening
at the same time?!? --------------------------- Hi, I
am having this very puzzling out of order execution. My setup is as following: I
have 4 filters, in this order – SecurityFilter, HibernateFilterLong,
JSF-Spring filter, myfaces ExtensionFilter. Now
look at the following trace, my comments in brackets. Can somebody please
explain? Regards, Yee ------------------------------------------------------------------------------------- INFO:
