Issue TISTUD-5984: Studio: Debug perspective went blank with no views when switching to it
Allen saw an issue when switching between Studio and Debug perspectives where the debug perspective would go completely blank with no views, and in one instance Studio beachballed, although running jstack showed no blocking thread. The Studio log contains the following repeated exceptions: {code} !ENTRY org.eclipse.ui 4 0 2014-01-06 14:23:20.056 !MESSAGE Unhandled event loop exception !STACK 0 org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:4397) at org.eclipse.swt.SWT.error(SWT.java:4312) at org.eclipse.swt.SWT.error(SWT.java:4283) at org.eclipse.swt.widgets.Widget.error(Widget.java:783) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:573) at org.eclipse.swt.widgets.Control.getBounds(Control.java:1606) at com.appcelerator.titanium.ui.ide.tiappEditor.TiAppDeployTargetsSection$5.getDecorationRectangle(TiAppDeployTargetsSection.java:536) at org.eclipse.jface.fieldassist.ControlDecoration$5.paintControl(ControlDecoration.java:626) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:230) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4166) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1466) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1489) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1474) at org.eclipse.swt.widgets.Control.drawWidget(Control.java:1244) at org.eclipse.swt.widgets.Widget.drawRect(Widget.java:749) at org.eclipse.swt.widgets.Display.windowProc(Display.java:5534) at org.eclipse.swt.internal.cocoa.OS.objc_msgSendSuper(Native Method) at org.eclipse.swt.widgets.Display.applicationNextEventMatchingMask(Display.java:4918) at org.eclipse.swt.widgets.Display.applicationProc(Display.java:5296) at org.eclipse.swt.internal.cocoa.OS.objc_msgSend(Native Method) at org.eclipse.swt.internal.cocoa.NSApplication.nextEventMatchingMask(NSApplication.java:94) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3645) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:1113) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:997) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:138) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:610) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:567) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) at com.appcelerator.titanium.rcp.IDEApplication.start(IDEApplication.java:125) 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:354) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:181) 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:636) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:591) at org.eclipse.equinox.launcher.Main.run(Main.java:1450) {code}
