Can you clarify what this part of the documentation means? anonymous wrote : maps. In this case, each element of the field-element is expected to have one subelement key and one element value. The key and element are both parsed using the conversion rules recursively. Just the same as with collections, a conversion to java.lang.String is assumed if no type attribute is specified. (from http://docs.jboss.org/jbpm/v3/userguide/jpdl.html#configtypefield) I would have figured that parsing the elements recursively meant that the elements could any type, and that they'd be parsed like a base element. Maybe I'm misinterpreting what the docs are saying? Thanks again.... View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4233723#...
