Hello,
wenn I try to align several controls via action tool bar (e.g. "Align left edges"), an error occurrs and the error page is shown with the following stack trace:
java.lang.ClassCastException: org.eclipse.wb.internal.xwt.model.widgets.CompositeInfo cannot be cast to org.eclipse.wb.internal.swt.model.widgets.CompositeInfo
at org.eclipse.wb.internal.swt.model.layout.absolute.SelectionActionsSupport.isValidObjectOnRootPath(SelectionActionsSupport.java:54)

at org.eclipse.wb.internal.core.gef.policy.layout.absolute.actions.AbstractAlignmentActionsSupport$SelectionAction.run(AbstractAlignmentActionsSupport.java:272)
....
Is it a bug or I use it wrong? If it is a known bug, is it planned to fix it?
Thank you.
Elena
