FW: Terminating event for EXTSRV

[Rankin, Andrew AJ]

Hi all,

I just thought I'd provide an answer to my own question for thoise who
may be interested.
We debugged the WfXHandler portal component and found that in order to
sucessfully complete the terminating event EXTSRV.COMPLETED, you have to
do the following:

1) Generate a random number
2) Execute SWK_EXEC_GUID_SET for you work item, passing the random no in
parameter IM_EXECGUID
3) Execute SWK_WI_COMPLETE_WITH_EVENT
This seems to be working ok in our modified component, which saves us
from having to make any changes to the workflow defn so that it may
operate in EP6.
