I'm not sure I totally get where what exactely your problem is. Is it just the GPD? Since complext structure like this should work in 3.2 engine, at least if the variable parent is of type org.dom4j.Element. You can read this in chapter 18.2.3.1 of the 3.2 docs and also have a look at the FieldInstantiatorTest.java in org.jbpm.instantiator package of the tests.
