Description Claudio Guglielmo

2011-08-18 03:52:04 EDT

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.
