Subject RE: Access to variable ends in selection failure
Date Tue, 15 Jan 2008 14:42:38 GMT
Hi!
Does the declaration of the prefix for xsd:faultString from the xpath
match the declaration of the prefix types: from <xsd:element ref="types:faultString"/>?
-Doug.

Subject: Access to variable ends in selection failure



Hello,

I try to get an access to a fault which is thrown by a service and catched
by a faulthandler inside a process.

I tried to access the variable faultString inside the faulthandler

<bpws:copy><bpws:from
xmlns:bpws="http://schemas.xmlsoap.org/ws/2004/03/business-process/"><![CDATA[$cisLogFault.logFaultException/xsd:faultString]]></bpws:from>
                            <bpws:to
xmlns:bpws="http://schemas.xmlsoap.org/ws/2004/03/business-process/"><![CDATA[$output.payload/tns:result]]></bpws:to>
                        </bpws:copy>

and get this error message:

13:52:44,529 ERROR [ASSIGN] Assignment Fault:
{http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure,lineNo=66,faultExplanation=No
results for expression: {OXPath10Expression /xsd:faultString}


cisLogFault is specified as:

<wsdl:message name="logFaultException">
		<wsdl:part name="logFaultException" element="types:LogFault">
		</wsdl:part>
</wsdl:message>

 <xsd:element name="LogFault">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element ref="types:faultCode"/>
                <xsd:element ref="types:faultString"/>
                <xsd:element ref="types:faultActor"/>
                <xsd:element ref="types:faultDetail"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>

The elements faultCode etc. are specified as built-in Strings.

log-file with the fault response of the service and the selection failure:

What´s the problem? Has anybody an idea?
