After refreshing a couple of expanded folders on dstore, ssh, or ftp I get a NPE error. Error Log: Unhandled event loop exception org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException) at org.eclipse.swt.SWT.error(SWT.java:3563) at org.eclipse.swt.SWT.error(SWT.java:3481) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:126) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3659) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3296) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2389) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2353) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2219) at org.eclipse.ui.internal.Workbench$4.run(Workbench.java:466) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:289) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:461) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:106) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:153) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:106) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:76) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:363) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:176) 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:504) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:443) at org.eclipse.equinox.launcher.Main.run(Main.java:1169) at org.eclipse.equinox.launcher.Main.main(Main.java:1144) Caused by: java.lang.NullPointerException at org.eclipse.rse.internal.ui.view.SystemViewLabelAndContentProvider.hasChildren(SystemViewLabelAndContentProvider.java:393) at org.eclipse.rse.internal.ui.view.SystemView.isExpandable(SystemView.java:5969) at org.eclipse.jface.viewers.AbstractTreeViewer.isExpandable(AbstractTreeViewer.java:2040) at org.eclipse.jface.viewers.AbstractTreeViewer.updateChildren(AbstractTreeViewer.java:2462) at org.eclipse.jface.viewers.AbstractTreeViewer.updateChildren(AbstractTreeViewer.java:2434) at org.eclipse.rse.internal.ui.view.SystemView.internalRSERefreshStruct(SystemView.java:3140) at org.eclipse.rse.internal.ui.view.SystemView.internalRSERefreshStruct(SystemView.java:3151) at org.eclipse.rse.internal.ui.view.SystemView.internalRefreshStruct(SystemView.java:3124) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh(AbstractTreeViewer.java:1797) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh(AbstractTreeViewer.java:1753) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh(AbstractTreeViewer.java:1739) at org.eclipse.rse.internal.ui.view.SystemView.doOurInternalRefresh(SystemView.java:3113) at org.eclipse.rse.internal.ui.view.SystemView.ourInternalRefresh(SystemView.java:3062) at org.eclipse.rse.internal.ui.view.SystemView.smartRefresh(SystemView.java:3426) at org.eclipse.rse.internal.ui.view.SystemView.smartRefresh(SystemView.java:3390) at org.eclipse.rse.internal.ui.view.SystemView.refreshRemoteObject(SystemView.java:2978) at org.eclipse.rse.internal.ui.view.SystemView$ResourceChangedJob.runInUIThread(SystemView.java:2207) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:94) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:123) ... 23 more -----------Enter bugs above this line----------- TM 2.0 Testing installation : eclipse-SDK-3.3 RSE install : RSE 2.0 java.runtime : Sun 1.5.0_11-b03 os.name: : Windows XP, Service Pack 2 ------------------------------------------------
*** Bug 197551 has been marked as a duplicate of this bug. ***
Created attachment 74402 [details] Patch fixing the NPE Problem was that with the fix for bug #197484, we were also wrapping the "Pending" node from the DeferredWorkbenchAdapter with a ContextObject. But that "Pending" node does not have an ISystemViewElementAdapter associated. Slightly changing the logic to unwrap the element in case no adapter is registered fixes the issue.
Patch committed and released for I20070723-1930: [197550] Fix NPE when refreshing Pending items SystemViewLabelAndContentProvider
Verified with I20070724-0735.
