From the branch dialog I selected delete to remove an old branch (which was actually the same commit as my current branch) and the 'Widget is disposed error' occurred. The history view was on screen so perhaps it was the branch tag widget? The history was showing the branch however after the delete operation its no longer visible in history even though its visible in the Branch list dialog. Using latest nightly build.
Same thing here. Here is the exception: org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:4083) at org.eclipse.swt.SWT.error(SWT.java:3998) at org.eclipse.swt.SWT.error(SWT.java:3969) at org.eclipse.swt.widgets.Widget.error(Widget.java:466) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:403) at org.eclipse.swt.widgets.Tree.getSelection(Tree.java:1708) at org.eclipse.jface.viewers.TreeViewer.getSelection(TreeViewer.java:256) at org.eclipse.jface.viewers.TreeViewer.setSelection(TreeViewer.java:344) at org.eclipse.jface.viewers.AbstractTreeViewer.setSelectionToWidget(AbstractTreeViewer.java:2480) at org.eclipse.jface.viewers.AbstractTreeViewer.setSelectionToWidget(AbstractTreeViewer.java:2903) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1429) at org.eclipse.jface.viewers.TreeViewer.preservingSelection(TreeViewer.java:403) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1383) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:1485) at org.eclipse.jface.viewers.ColumnViewer.refresh(ColumnViewer.java:537) at org.eclipse.ui.dialogs.FilteredTree$NotifyingTreeViewer.refresh(FilteredTree.java:1208) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:1444) at org.eclipse.ui.dialogs.FilteredTree$NotifyingTreeViewer.refresh(FilteredTree.java:1198) at org.eclipse.egit.ui.internal.dialogs.BranchSelectionDialog$3$1.postExecuteSuccess(BranchSelectionDialog.java:188) at org.eclipse.core.commands.Command.firePostExecuteSuccess(Command.java:641) at org.eclipse.core.commands.Command.executeWithChecks(Command.java:477) at org.eclipse.egit.ui.internal.dialogs.BranchSelectionDialog$3.widgetSelected(BranchSelectionDialog.java:202) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:234) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1258) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3540) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3161) at org.eclipse.jface.window.Window.runEventLoop(Window.java:825) at org.eclipse.jface.window.Window.open(Window.java:801) at org.eclipse.egit.ui.internal.branch.BranchOperationUI.start(BranchOperationUI.java:92) at org.eclipse.egit.ui.internal.actions.BranchActionHandler.execute(BranchActionHandler.java:29) at org.eclipse.egit.ui.internal.actions.RepositoryAction.run(RepositoryAction.java:85) at org.eclipse.ui.internal.PluginAction.runWithEvent(PluginAction.java:251) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:584) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:501) at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributionItem.java:411) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1258) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3540) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3161) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:369) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407)
I think this is due to an execution listener not being cleaned up and refreshing a branch tree from a previous invocation of the branch selection dialog.
