UIPanelMenu selectedName property read-only?

[dumbuzz]

I have a UIPanelMenu (HtmlPanelMenu) component in session bean.
When I select some menu item, the selectedName takes some value.
Then I live page.
And when I come to this page I see the same node expanded (though I programmatically cleared selectedChild property and recursive collapse all childs of my menu).
During debuggung I see that all nested groups have expand = false, selectedChild = "", but selectedName != "", so I think during renderResponce UIPanelMenu watches, that selectedName != null and expand appropriate MenuGroup again.

Why this property doesn't have setter method??

Nobody faced this problem so far??

Well, just ask me a question, how to programmatically collapse all nested groups of HtmlPanelMenu component, that stored in session scope.
