Subject [jira] Updated: (ODE-498) XPath variables used in predicates (e.g. element[$index]) cause bpel:selectionFailure
Date Fri, 23 Jan 2009 22:23:59 GMT

     [ https://issues.apache.org/jira/browse/ODE-498?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Karthick Sankarachary updated ODE-498:
--------------------------------------

    Attachment: evaluate-embedded-variable-reference.patch

The root cause of this issue was a failure by the BPEL compiler, under certain circumstances,
to properly evaluate XPath expressions containing variable references. In particular, if the
compiler runs into a function reference in the XPath, it summarily short circuits the evaluation
of the XPath, thereby ignoring any subsequent variable references. This leads the runtime
to believe that that variable is undefined, hence the selection failure.

> As reported on the mailing list,
>  I found another BUG-like problem in  ODE 2.0 Build #87 (2009-1-8 2:25:04). That is:
the counterName variable can't be used in the position expression of XPath as normal variables
are. For example, the following BPEL piece
>          <forEach counterName="i" parallel="no">
>                  <startCounterValue>1</startCounterValue>
>                  <finalCounterValue>2</finalCounterValue>
>                  <scope>
>                    <assign>
>                      <copy>
>                        <from>$i</from>
>                        <to>$output0.body/xsd0:field1[position()=$i]</to>
    <!-- note this line -->
>                      </copy>
>                    </assign>
>                  </scope>
>                </forEach>
> will incur such ERROR in ODE:
> ERROR - GeronimoLog.error(104) | Assignment Fault: {http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure,lineNo=149,faultExplanation={http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure:
