Hello everybody,
I have a newbie question concerning XPath in a BPEL while construct:
The condition of the following while always evaluates to 'true':
<while> <condition>
$processState_internal != 'empty_before_FAILURE' and
$processState_internal != 'empty_before_SUCCESS'
</condition>
<sequence>
...
<assign>
<copy>
<from>
<literal>
<wsdlDoc:state_InternalType>empty_before_SUCCESS</wsdlDoc:state_InternalType>
</literal>
</from>
<to>
$processState_internal
</to>
</copy>
</assign>
</while>
Does anybody know why? If the XPath expression is wrong, what would be
the correct one?
The following while loop terminates as desired:
<while> <condition>
$processState_internal != 'empty_before_SUCCESS'
</condition>
<sequence>
...
<assign>
<copy>
<from>
<literal>
<wsdlDoc:state_InternalType>empty_before_SUCCESS</wsdlDoc:state_InternalType>
</literal>
</from>
<to>
$processState_internal
</to>
</copy>
</assign>
</while>
Any hint is greatly appreciated!
Regards,
Christoph
