Build Identifier: 3.7.0 When using a htmlfield inside a tabbox a widget is disposed exception can occur. For some reason the component org.eclipse.swt.ole.win32.OleClientSite creates a TRAVERSE_TAB_NEXT event when its getting disposed. This leads to a SwtScoutTabItem#setUiFocus() call which generates the exception. org.eclipse.swt.SWTException: Failed to execute runnable (org.eclipse.swt.SWTException: Widget is disposed) at
