After installing the Web Tools Platform from the Eclipse.org Update Site the graphical xdoclect component ceases to work -------------------------------------------------------------------------------------------------------------------------- Key: JBIDE-242 URL: http://jira.jboss.com/jira/browse/JBIDE-242 Project: JBoss Tools Issue Type: Bug Environment: Version: 3.1.0 Build id: I20050627-1435 Reporter: Ricardo C?mara The Web Tool Platform, when installed from the eclipse.org update site allows the automatic installation of several upgrades and/or used projects that allow it to display graphical XSD diagrams. Once I installed the Web Tool Platform, JBoss IDE seems unable to display the contents of the .xdoclet file (via the [Right Click on project]->properties->XDoclet Configuration. ) Eclipse displays a dialog box "The currently displayed page contains invalid values" and the error log displays the following stack trace: java.lang.NoClassDefFoundError: org/eclipse/ui/internal/dialogs/ListContentProvider at org.jboss.ide.eclipse.xdoclet.run.ui.ConfigurationListViewer.<init>(ConfigurationListViewer.java:90) at org.jboss.ide.eclipse.xdoclet.run.ui.properties.ConfigurationPropertyPage.createContents(ConfigurationPropertyPage.java:275) at org.eclipse.jface.preference.PreferencePage.createControl(PreferencePage.java:232) at org.eclipse.jface.preference.PreferenceDialog.createPageControl(PreferenceDialog.java:1371) at org.eclipse.jface.preference.PreferenceDialog$12.run(PreferenceDialog.java:1138) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1044) at org.eclipse.core.runtime.Platform.run(Platform.java:783) 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:1132) at org.eclipse.ui.internal.dialogs.FilteredPreferenceDialog.showPage(FilteredPreferenceDialog.java:351) at org.eclipse.jface.preference.PreferenceDialog$8.selectionChanged(PreferenceDialog.java:638) at org.eclipse.jface.viewers.StructuredViewer$3.run(StructuredViewer.java:763) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1044) at org.eclipse.core.runtime.Platform.run(Platform.java:783) 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:123) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3057) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2716) 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) While I was testing this problem, I also tried to install the 1.5 Milestone 3 and, though I was able to see the XDoclet properties again, I was unable to either view the graphical representation of an XSD or to revert my installation to a stable configuration.
