Compensation handler and compensate activity doesn't work

Question

Hi!
i'm trying to build process with compensation handlers and it doesn't work .. to test it i made the following example:
in scope_1 there is simple assign_1 and in compensation handler there is assign_2. after scope_1 i throw error and in catchAll branch i have compensate activity - calling compensation of scope_1. But that compensation activity is never invoked! can please someone tell me why? what am i doing wrong?
I have bpel 10.1.2 ...
Thanks, Tomas

this might be caused by a bug I found too causing eventhandlers not to work, the work round in your case would be:
blar blar blar
</variables>
<!-- start work round --><scope><!-- end work round -->
<faultHandlers>
blar blar blar
blar blar blar
</sequence>
<!-- start work round --></scope><!-- end work round -->
</process>
i.e. what I'm saying is that top level handler don't work since they are ignored by the engine because they are not in a scope. Try it and see....
