This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Steps to reproduce: - create a sync process - add a correlation set without any properties to the process - add this correlation set to the receive activity - select the correlation set in the Navigator and click Edit in context menu - Correlation set property editor will be opened. Change set name and click OK button. Exception will be thrown: java.lang.ClassCastException: org.openide.nodes.Children$Empty at org.netbeans.modules.bpel.nodes.CorrelationSetNode.reload(CorrelationSetNode.java:72) at
