NullPointerException when trying to rename method ------------------------------------------------- Key: JBIDE-6054 URL: https://jira.jboss.org/jira/browse/JBIDE-6054 Project: Tools (JBoss Tools) Issue Type: Bug Affects Versions: 3.1.0.GA Reporter: Vadim Berezniker I have a seam-gen ant based project. When I attempt to rename a method, the refactoring process sits there for a bit in "Checking preconditions" state and then I get an error dialog that says "The participant '<method name>' caused an internal error and has been disabled for refactoring." The following exception is seen in the Eclipse log right after the message: !ENTRY org.eclipse.ltk.core.refactoring 4 10000 2010-03-13 00:18:41.025 !MESSAGE Internal Error !STACK 0 java.lang.NullPointerException at org.jboss.tools.common.el.core.ca.AbstractELCompletionEngine.resolveELOperand(AbstractELCompletionEngine.java:256) at org.jboss.tools.common.el.core.ca.AbstractELCompletionEngine.resolve(AbstractELCompletionEngine.java:131) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.searchInCach(RefactorSearcher.java:210) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.scan(RefactorSearcher.java:188) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.scan(RefactorSearcher.java:148) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.scan(RefactorSearcher.java:146) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.scan(RefactorSearcher.java:146) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.scan(RefactorSearcher.java:146) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.scan(RefactorSearcher.java:146) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.scan(RefactorSearcher.java:146) at org.jboss.tools.jsf.el.refactoring.RefactorSearcher.findELReferences(RefactorSearcher.java:114) at org.jboss.tools.jsf.ui.el.refactoring.RenameMethodParticipant.checkConditions(RenameMethodParticipant.java:70) at org.eclipse.ltk.core.refactoring.participants.ProcessorBasedRefactoring.checkFinalConditions(ProcessorBasedRefactoring.java:257) at org.eclipse.ltk.core.refactoring.CheckConditionsOperation.run(CheckConditionsOperation.java:85) at org.eclipse.ltk.core.refactoring.CreateChangeOperation.run(CreateChangeOperation.java:121) at org.eclipse.ltk.core.refactoring.PerformChangeOperation.run(PerformChangeOperation.java:211) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1800) at org.eclipse.ltk.internal.ui.refactoring.WorkbenchRunnableAdapter.run(WorkbenchRunnableAdapter.java:87) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) I recently updated to 3.1 -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
