Bug 94304 [code manipulation] Fails to create a class in enum
With Eclipse I20050506-1600, I run a problem to create a inner class in enum: 1. select an enum in the package explorer 2. call new wizard to create a inner class 3. check the "Enclosing type" 4. Put a name in the "Name:" Field 5. Click the button "OK". I got the following exception: Caused by: java.lang.IllegalArgumentException: Node does not exist at org.eclipse.jdt.core.dom.rewrite.ListRewrite.insertBefore (ListRewrite.java:205) at org.eclipse.jdt.internal.core.CreateElementInCUOperation.insertASTNode (CreateElementInCUOperation.java:249) at org.eclipse.jdt.internal.core.CreateElementInCUOperation.generateNewCompilation UnitAST(CreateElementInCUOperation.java:184) at org.eclipse.jdt.internal.core.CreateElementInCUOperation.executeOperation (CreateElementInCUOperation.java:137) at org.eclipse.jdt.internal.core.JavaModelOperation.run (JavaModelOperation.java:718) at org.eclipse.core.internal.resources.Workspace.run (Workspace.java:1716) at org.eclipse.jdt.internal.core.JavaModelOperation.runOperation (JavaModelOperation.java:782) at org.eclipse.jdt.internal.core.SourceType.createType (SourceType.java:153) at org.eclipse.jdt.ui.wizards.NewTypeWizardPage.createType (NewTypeWizardPage.java:1808) at org.eclipse.jdt.internal.ui.wizards.NewClassCreationWizard.finishPage (NewClassCreationWizard.java:55) at org.eclipse.jdt.internal.ui.wizards.NewElementWizard$2.run (NewElementWizard.java:114) at org.eclipse.jdt.internal.core.BatchOperation.executeOperation (BatchOperation.java:39) at org.eclipse.jdt.internal.core.JavaModelOperation.run (JavaModelOperation.java:718) at org.eclipse.core.internal.resources.Workspace.run (Workspace.java:1716) at org.eclipse.jdt.core.JavaCore.run(JavaCore.java:3654) at org.eclipse.jdt.internal.ui.actions.WorkbenchRunnableAdapter.run (WorkbenchRunnableAdapter.java:87) at org.eclipse.jface.operation.ModalContext.runInCurrentThread (ModalContext.java:346) The samething can be done in Java editor.
