After pressing "ok" in the property dialog the widget is going to be moved to
the other package, which is handled in 

>	umbrello.exe!UMLListView::moveObject(std::basic_string<char,std::char_traits<char>,std::allocator<char> > srcId, 

In fact a new widget is created and the old one deleted  

    case UMLListViewItem::lvt_Datatype:
        if (newParentType == UMLListViewItem::lvt_Logical_Folder ||
                newParentType == UMLListViewItem::lvt_Datatype_Folder ||
                newParentType == UMLListViewItem::lvt_Logical_View ||
                newParentType == UMLListViewItem::lvt_Class ||
                newParentType == UMLListViewItem::lvt_Interface ||
                newParentType == UMLListViewItem::lvt_Package) {
            newItem = move->deepCopy(newParent);
            if (m_doc->loading())         // deletion is not safe while loading
                move->setVisible(false);  // (the <listview> XMI may be
corrupted)
            else
!               delete move;

which means that 'temp' the current list view item is destroyed.
