GPD crashes if xmlbuddy plugin is installed ------------------------------------------- Key: JBPM-587 URL: http://jira.jboss.com/jira/browse/JBPM-587 Project: JBoss jBPM Issue Type: Bug Components: Graphical Process Designer Affects Versions: jBPM GPD 3.0.8 Environment: Gentoo Linux / Eclipse 3.1.2 Reporter: Matthias Germann Assigned To: Tom Baeyens If the Graphical Process Designer plugin and the XML Buddy Plugin are installed in the same eclipse installation, the GPD crases when opening a process definition file. The problem can be reproduced by unzipping the XML Buddy Free Edition ZIP File into the plugins directory of a eclipse installation with GPD installed. The GPD reports the following error when opening a jBPM process definition File: Unable to create this part due to an internal error. Reason for the failure: An unexpected exception was thrown.
