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.
