Hi Rafal,
a NPE is not exactly what we want to see here :) What it however says is
that the wsa:Address element could not be extracted from the message, so
I assume that the XML nesting was somehow wrong.
Could you please set the log level for "org.apache.ode.bpel.epr" to
DEBUG, run the example again and look for "Setting a WSAEndpoint value"?
With that log information it should be easier to understand what is
going wrong. Also, did you check out the DynPartner example shipped with
ODE? I recently tried it with ODE 1.3.5rc and it worked as expected.
HTH,
Tammo
