Hi Thomas,
We're still missing some of the context here; it's not clear what your
getRuntime() does but one thing it shouldn't do is to reuse the same
BpelRuntimeContext from another thread/transaction.
It looks like you're executing this code from another thread so perhaps you
need to create a new BpelRuntimeContext. Look at
PartnerLinkMyRoleImpl.invokeInstance() as a basis for this. Ideally this
would be encapsulated by the engine (and a specific external event) rather
than doing all this work outside the engine.
Hope we're getting closer this time,
alex
