Simon, The PD is xml, it is fairly easy to retrieve, make a Document out of it and retrieve e.g. via xpath the required fields. The change you want will most likely not be done before jBPM 4. npe: in that case the other solution will indeed not work. Generating xml from the PD object is not supported anymore (jpdlxmlwriter is deprecated) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110820#...
