Sathwik Bantwal Premakumar commented on ODE-965:
------------------------------------------------
The event handler has to be defined within a sub scope after the correlation
has been initiated.
{code:xml}
<bpel:invoke name="Invoke" partnerLink="bpelProcessPartner"
operation="initiate" portType="ns0:echoAsynchProcess"
inputVariable="bpelProcessPartnerRequest1">
<bpel:correlations>
<bpel:correlation set="CorrelationSet"
initiate="join"></bpel:correlation>
</bpel:correlations>
</bpel:invoke>
<bpel:scope name="raiseFault">
<bpel:eventHandlers>
<bpel:onEvent partnerLink="callback"
operation="callback"
variable="callbackRequest"
messageType="ns0:echoAsynchProcessResponseMessage">
<bpel:correlations>
<bpel:correlation
set="CorrelationSet" initiate="join"></bpel:correlation>

> Hi,
> I got a very simple test:
> On computer A a BPEL process invokes an asynchronous call to computer B.
> Afterwards it waits for 15 seconds. Furthermore an eventHandler is launched
> waiting for the response from B and throw an exception when activated.
> B is an echo service which simply returns the string it gets.
> Additionally I watch the network traffic using wireshark.
> Because the computer standing next to each other there are no high reponse
> times. Therefore 15 seconds should be enough to receive the reply. I'd
> expected getting an exception everytime I call the BPEL process. But very
> often this doesn't happen. But everytime I get the answer from B (wireshark
> tells me).
> So I guess there is a bug with the eventHandler?
