[jbpm-users] Context Variable Mappings

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> <matcher> <bean class="com.erudine.MyMatcher" /> </matcher> <converter class="com.erudine.MyConvertor" /> <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. ___________________________ Andrew Norman Developer www.erudine.com <http://www.erudine.com/> T: +44 (0) 1423 522 336 M: +44 (0) 7824 310 089 This email and any files transmitted with it are confidential and solely for the use of the intended recipient.
