Terminating event -- No active receiver found

Question

Hi -- on an Integration project I just need a workitem that stays active until explicitly closed via an event..
It's easy enough to create a triggering event which starts a process.
I've followed all the rules (as far as I can see) to create a terminating event but it doesn't work.
I've created a test Bus Obj ZZJIMBO which simply has a key of the SAP user ID.
I've defined 3 events
STARTSYN  ====> Synchronous
STARTASY  =====> Asynchronous
FINISHED ======>  terminating
Using SAP_WAPI_CREATE_EVENT the STARTSYN and STARTASY  are triggered and the relevant processes start - both for the synchronous and asynchronous tasks.
However on raising the FINISHED event the system just errors with NO Active receiver found.
All the binding etc is fine and SWU0 doesn't find any problems.
Looking at the instance table (transaction SWE3)
I see that the eventid is the same as the current workitem but the object key is empty
object key  <empty> 
eventid    000000250100
The only possibility I can see is that my Business object doesn't really have "instances" like say a sales order as it only exists at run time.
Would I have to say trigger the event finished using something like the Work item itself which does have a valid individual instance -- I can extend the WORKITEM bus obj and add an event FINISHED to it instead.
I can get the workitem id via the container so that shouldn't in theory be a problem to "instantiate"  the Workitem (or ZWORKITEM) business object.
I really hoped to have all the events in the SAME business object however.
Any ideas
Cheers

Hi James.
1. Yes, I think the workitem in runtime would expect the triggering event should be from the instance of the object either from
        a. standard workitem relevant obejct instances like _WORKITEM, ATTACHOBJECTS, RULERESULT
       b. or the associated BO in the task i.e WIOBJECT_ID
2. However as you say >>I really hoped to have all the events in the SAME business object however>>. I can suggest the following
       a. create a parallel fork to the step which is creating your workitem
       b. In this parallel branch create step 'Wait for Event; and refer it to your ZZJIMBO.FINISHED.
      c. define necessary branches required to complete the fork as 1. meaning, if any one of the branch ends flow will continue to next step in main workflow.
So, when the event ZZJIMBO.FINISHED is raised with the correct instance which was used in workflow. 'Wait for event' will receive it and this branch will end and eventually other branch will get logically deleted. You can put some flag in the 'Wait for event' branch using which u can understand whether the workitem is completed in normal way or through exeption.
Hope this helps !!
