bpel:condition seems to incorrectly return false on some xpath expressions
--------------------------------------------------------------------------
Key: ODE-178
URL: https://issues.apache.org/jira/browse/ODE-178
Project: ODE
Issue Type: Bug
Components: BPEL Runtime
Affects Versions: 1.1
Environment: unix/windows
Reporter: jan cwik
I'm trying to do copying based on the node existance. That is first I want to
find out if xpath query returns any value. Then I'm going to copy this value to
the variable. The following is the bpel snippet that does it. This is the
simplified version of the larger project. I managed to reproduce this issue on
the modified loan-broker sample.
It looks like the "boolean($request.body/hello:hello)" returns false since the
copying of the request to response is never done. However, when I removed the
"bpel:if" statement the copying is performed successfully. I have tested both
exists and boolean functions.
I increased the logging level in ServiceMix (orga.apache.ode=DEBUG), but I saw
no entry in the logs that indicates that the "bpel:condition" was processed or
not, there was no warning or error present.
<bpel:if>
<bpel:condition
expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">boolean($request.body/hello:hello)</bpel:condition>
<bpel:copy>
<bpel:from>$request.body/hello:hello</bpel:from>
<bpel:to>$response.body/hello:hello</bpel:to>
</bpel:copy>
</bpel:if>
Please take a look at attached modified loan-broker sample. In the wsdl there
is schema for the very simple request, in the bpel there is bpel:condition
statement and in the JMSClient there is requests that is sent to ODE (command
line: ant run)
