Error when executing the testCAforIncludeTaglibInInenerNodes VPE JUnit test --------------------------------------------------------------------------- Key: JBIDE-2128 URL: http://jira.jboss.com/jira/browse/JBIDE-2128 Project: Tools (JBoss Tools) Issue Type: Bug Components: Visual Page Editor Affects Versions: 2.1.0.beta1 Reporter: Snjezana Peco Assigned To: Snjezana Peco Priority: Minor Sometimes, the VpeController.notifyChanged method is called when the VPE is disposed. This causes NPE. The solution is to check if the editor is disposed and, if it is,.not to execute the method. This error occurs randomly.
