Hi Philipp, right, I get the same error. If I add org.eclipse.jface.text in the Dependencies section of the plugin.xml editor (jface.text was clearly missing), add dom4j-1.4.jar under Java Build Path / Libraries / Add Jars / org.jbpm.gd.bpel/lib, reorganize the imports (Ctrl + Shift + O), add org.dom4j.Element, I still get a single compile error "The method getAttribute(String) is undefined for the type Element" in JpdlContentProvider.java. Strange. Karl View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125892#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
