What's the purpose of the Closable and CloseAction property on a Portlet? Setting Closable = true does not automatically add a close tool to the Portlet. There's no Portlet.close() clientside function. Only Portlet.hide(). If I want to close a portlet and destroy it completely, how do I do that? Portlet.hide(); Portlet.destroy(); ? Will that clean up ALL child controls inside the Portlet?
