Is there a way to change/debug theJBPM process modeler standalone because trying to do this as an iframe inside the JBPM GWT framework is very challenging.
best to use gwt hosted mode, then you can define all server side and gwt client side parts. Though not much of debugging of java script in regular sense. Firebug or similar might help with that.
To debug designer standalone in hosted mode go into jbpm-designer-standalone project and start it with: mvn gwt:debug
