<div class="jive-rendered-content"><p>Hi Mauricio,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks for your reply.  I'll give more info behind what I am trying to do.  I have an object model which looks something like this:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Class A</p><p>   String id</p><p>  Set<ClassB> data --> ClassB String name, String value</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>In my flow we create Class A and a collection of ClassB but in the process variable we store the reference as opposed to the serialised version of ClassA (there is already persistence behind ClassA).</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Name: ClassA(variableName defined in flow).elementName + ':'  + ClassA(variableName defined in flow).reference</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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.      </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Hope this made sense!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Cheers</p></div>
