Subject Re: Display tobago selectable tree
Date Wed, 20 Dec 2006 13:25:28 GMT
the getter of the TreeState is imho the wrong place to capture the selection.

this should be done in the action method werd the result is stored.

the way you do this is ok, but you will get the selection before
rendering, not the one after submitting the page.
