(eclipse 3.1.RC1, ajdt dev 1.2.0.20050525133001) When attempting to open the JavaBuildPath project properties page an error dialog is displayed "The currently displayed page constains invalid values" and the following error is produced in the log. This /only/ occurs with 3.1.RC1. With 3.1.M7 this does not occur. java.lang.NoSuchMethodError: org.eclipse.jdt.internal.ui.wizards.buildpaths.ProjectsWorkbookPage.<init>(Lorg/eclipse/jdt/internal/ui/wizards/dialogfields/ListDialogField;)V at org.eclipse.ajdt.buildconfigurator.propertypage.BuildPathsBlock.createControl(BuildPathsBlock.java:241) at org.eclipse.ajdt.buildconfigurator.propertypage.BCPropertyPage.createWithJava(BCPropertyPage.java:131) at org.eclipse.ajdt.buildconfigurator.propertypage.BCPropertyPage.createContents(BCPropertyPage.java:67) at org.eclipse.jface.preference.PreferencePage.createControl(PreferencePage.java:232) at org.eclipse.ajdt.buildconfigurator.propertypage.BCPropertyPage.createControl(BCPropertyPage.java:77) at org.eclipse.jface.preference.PreferenceDialog.createPageControl(PreferenceDialog.java:1376) at org.eclipse.jface.preference.PreferenceDialog$12.run(PreferenceDialog.java:1139) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1038) at org.eclipse.core.runtime.Platform.run(Platform.java:775) at org.eclipse.ui.internal.JFaceUtil$1.run(JFaceUtil.java:44) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:148) at org.eclipse.jface.preference.PreferenceDialog.showPage(PreferenceDialog.java:1133) at org.eclipse.ui.internal.dialogs.FilteredPreferenceDialog.showPage(FilteredPreferenceDialog.java:351) at org.eclipse.jface.preference.PreferenceDialog$8.selectionChanged(PreferenceDialog.java:639) at org.eclipse.jface.viewers.StructuredViewer$3.run(StructuredViewer.java:763) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1038) at org.eclipse.core.runtime.Platform.run(Platform.java:775) at org.eclipse.ui.internal.JFaceUtil$1.run(JFaceUtil.java:44) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:148) at org.eclipse.jface.viewers.StructuredViewer.firePostSelectionChanged(StructuredViewer.java:761) at org.eclipse.jface.viewers.StructuredViewer.handlePostSelect(StructuredViewer.java:1042) at org.eclipse.jface.viewers.StructuredViewer$5.widgetSelected(StructuredViewer.java:1062) at org.eclipse.jface.util.OpenStrategy.firePostSelectionEvent(OpenStrategy.java:231) at org.eclipse.jface.util.OpenStrategy.access$4(OpenStrategy.java:226) at org.eclipse.jface.util.OpenStrategy$3.run(OpenStrategy.java:392) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:118) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:2906) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2565) at org.eclipse.jface.window.Window.runEventLoop(Window.java:809) at org.eclipse.jface.window.Window.open(Window.java:787) at org.eclipse.ui.dialogs.PropertyDialogAction.run(PropertyDialogAction.java:157) at org.eclipse.jface.action.Action.runWithEvent(Action.java:996) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:538) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:488) at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributionItem.java:400) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:844) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:2929) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2562) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1694) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1658) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:366) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:143) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:103) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:226) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:375) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:162) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:334) at org.eclipse.core.launcher.Main.basicRun(Main.java:278) at org.eclipse.core.launcher.Main.run(Main.java:973) at org.eclipse.core.launcher.Main.main(Main.java:948)
This is fixed and will be available in the next AJDT build which supports Eclispe 3.1 M7 (hopefully due out sometime today). The problem was that the Eclipse implementation changed between 3.1M7 and 3.1RC1.
