<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Fix: This patch sets the focus to helpLabel before the object is deleted. It does this by calling modeWidgetDestroyed(), which calls objectDestroyed() before the focus changing event will be invalid. </p></pre>
