deadlock question

Fri Sep 4 00:08:30 PDT 2015

 Hi ! I have a deadlock question to ask you.  I hope you can help me, thank
you!
I am trying to program a ContextMenuInterceptor by C++ in Secondary
development. but when I program in notifyContextMenuExecute method like ：

class ContextMenuInterceptor : public
WeakImplHelper1<XContextMenuInterceptor>
{
    virtual ContextMenuInterceptorAction SAL_CALL notifyContextMenuExecute(
const ContextMenuExecuteEvent& aEvent )
       throw (::css::uno::RuntimeException, ::std::exception);
}

ContextMenuInterceptorAction
ContextMenuInterceptor::notifyContextMenuExecute( const
ContextMenuExecuteEvent& aEvent )
{
 Reference<XSelectionSupplier> xSupplier = aEvent.Selection;
 Any any = xSupplier->getSelection();
}

It leads to deadlock.
