I think the refresh btn should be disabled when the connection is off. java.lang.NullPointerException at org.eclipse.jpt.jpa.ui.internal.wizards.gen.TablesSelectorWizardPage.refreshTa bles(TablesSelectorWizardPage.java:278) at org.eclipse.jpt.jpa.ui.internal.wizards.gen.TablesSelectorWizardPage.access$12 (TablesSelectorWizardPage.java:277) at org.eclipse.jpt.jpa.ui.internal.wizards.gen.TablesSelectorWizardPage$8.widgetS elected(TablesSelectorWizardPage.java:395) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:240) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1053) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:4165) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3754) at org.eclipse.jface.window.Window.runEventLoop(Window.java:825) at org.eclipse.jface.window.Window.open(Window.java:801) at org.eclipse.ui.internal.navigator.wizards.WizardShortcutAction.run(WizardShort cutAction.java:98) at org.eclipse.jface.action.Action.runWithEvent(Action.java:498) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionCo ntributionItem.java:584) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionIte m.java:501) at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributi onItem.java:411) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1053) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:4165) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3754) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2696) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2660) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2494) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:674) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:667) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.ja va:123) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:19 6) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(Ec lipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppL auncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) 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.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386)
Fixed in head.
Verified in Build I-3.4.0-20120104005037 Verified when you click on the refresh button no errors appear if the button is enabled. Also verified that if you are connected to a DB that is not connected to the DB at this time the buttons are disabled. See the link to view test steps for verification. http://wiki.eclipse.org/Dali_3.2_M5 However if you have more then one DB connection set-up and some of them are connected to their DB's and some are not if you go from one that is connected to one that is not connected the buttons stay enabled. This is now Bug 367884
