[jboss-user] [JBoss jBPM] - Context Variable Mappings

[AndrewNorman]

I am trying to get a non serialisable object to be stored in the context of a workflow process. 

I have updated the jbpm.cfg.xml file to point to my modiffed varmapping file, I then added the following XML snippet into jbpm.varmapping.xml file.

    <jbpm-type> 
                 
                         
                 
                 
                <variable-instance class="org.jbpm.context.exe.variableinstance.StringInstance" /> 
    </jbpm-type> 

I have written a Junit test case to verify that the number of types returned by the call JbpmType.getJbpmTypes() matches the number the is declared in the modified mapping file.

MyMatcher class just contains a "return obj instanceof MyClass" in it and the convertor object just returns a constant test string as the conversion to and from the database.

If I step through the list of the JbpmTypes from the object factory calling match() with an instant of MyClass I get a null pointer from the JbpmType that I think corresponds to the one I have written.

If I run a workflow ProcessInstance containing an action handler that attempts to store an instance of MyClass I get an hibernate exception complaining that I was attempting to put a non persistent variable into a persistent store.

Any suggestions would be helpful, I am at my wits end trying to get this fixed … I expect I have missed a simple step somewhere.
