I now have a domain specific work item handler which is registered in eclipse and has a set of properties which a user can define.  These properties can be statically defined or they can use an expression based approach for example Name: ClassA(variableName defined in flow).elementName + ':'  + ClassA(variableName defined in flow).reference The idea is then to load ClassA id via variableName and then get the value of elementName and reference which are stored in ClassA object model. I have a small ANTLR program that parses the string and then looks up the data.  The ANTLR parser uses session.getProcessInstance(..) to load the relevant data and I was hoping to load the process and get the value out, although it probably is possible to pass the work item parameter mapping to my parser.      Hope this made sense!

You should use the Variable Persisntece Strategies to handle such situations. Are your expessions propietary? Do you need to do that kind of resolutions in runtime? or you can solve the same things with the current methods? If you create a variable persistence strategy for handling your classes that are being persisted externally,  you shouldn't use the process instance ID to restore the information. You should use your own/external persisters (the one that handles the Class A and B) to restore the information about those classes using the ID that you pass to the work item handler. Greetings. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/609228#609228] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
