I appreciate your effort for answering me,,, I checked the the node type in 9.3.7,,, but my case is that i want to add a custom attributes to the class node itself,, in other words,, node class contains id as long,, and i want to add a type of node that contain myId as int,, and get its value from the processdefinition.xml,, i.e: <process-definition name="simple"> <custom-node myId="5"> ...... </custom-node> </process-definition> is there any solution,, or i have to rebuild the jpdl in order to do that??
