I tried to submit this to https://issues.jboss.org/secure/, but my password reset, while successful doesn't let me in to submit a JIRA. On the stable (M1?) version of 5.2 I encounter the following exception. - Create a BPMN2 diagram with a nest subprocess that has a rule task with ruleflow-group specified (or not) - Save it - Reopen it Dialog box in Eclipse: Could not read RuleFlow file An exception occurred while reading in the RuleFlow XML: the prefix "G" for attribute "g:ruleFlowGroup" associated with the element type "businessRuleTask" is not bound. See the error log for more details. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Attempted-JIRA-on-BPM...
