> All,

**Update:  I sent this to the wrong list earlier.  I currently have a work around, \
however, not as elegant as I would like. The problem persists.

> I am getting the error: java.lang.RuntimeException: Could not resolve the node to a \
> handle The error is very odd as it runs the first node successfully but throws an \
> exception on the second node, regardless of which node is executed ( I moved the \
> xml nodes around in the XML file).   
> Basically the program is parsing 2 files.  I file is the xml client data (No \
> problems even though I traverse the tree up and down) and the other is an xml \
> config file with xpath expressions in it.  An example of the xml I am trying to run \
> is (this is the xml config file): <!-- Runs fine -->
> <FieldMapping identifier="1.SubmissionType" xpath="SubmissionTypeCode/text()" \
> converter="com.infoterra.grantium.service.integration.datamapper.converters.impl.LookupConverter">
>   <ConverterAdditionalMapping>
> 		<LookUpInfo constant="SF424_SUBMISSION_TYPE/>
> 	</ConverterAdditionalMapping>
> </FieldMapping>
> 		
> <!-- exception is thrown -->		
> <FieldMapping identifier="2.ApplicationType" xpath="ApplicationTypeCode/text()" \
> converter="com.infoterra.grantium.service.integration.datamapper.converters.impl.LookupConverter">
>   <ConverterAdditionalMapping>
> 		<LookUpInfo constant="SF424_APPLICANT_TYPE"/>
> 	</ConverterAdditionalMapping>
> </FieldMapping>

> The java code that is calling the xpath is:
> //Note that this is recreated for every node.  Is this part of the problem?????
> XPathFactory xpathfactory= XPathFactory.newInstance();
> 
> XPath xpath  = xpathfactory.newXPath();
> 
> //converterAdditionalMappingNode is the <ConverterAdditionalMapping> node
> String lookupConstant = (String)xpath.evaluate("LookUpInfo/@constant", \
> converterAdditionalMappingNode, XPathConstants.STRING);  
> 
> Note that I have XMLBean'ed the config file so that I can traverse it with objects, \
> however the <ConverterAdditionalMapping> node is supposed to be client specific and \
> therefore cannot be XMLBean'ed.
