[richfaces-issues] [JBoss JIRA] (RF-12564) rich:tree throws js error in combination with c:if in IE9

Brian Leathem resolved RF-12564.
--------------------------------

    Resolution: Rejected


Unfortunately ajax updates are not compatible with the c:if tag, as the c:if tag will prevent the component from populating the initial component tree, and so the subsequent ajax update will fail.  Doing a full page load works, as the component tree is re-built on the full-page load.

Rather, use the _rendered_ attribute of the tree, with your ajax update targeting a JSF panel wrapping the tree to conditionally render your tree in an ajax update.

> I use a rich:tree inside a c:if tag.
> A js error occurs if the tree is rendered via ajax the first time.
> It works fine if the complete view is reloaded afterwards or if there is no c:if tag around.
> I tested with with Internet Explorer Version 9.0.8112.16241, Update versions 9.0.10
> Workarounds:
> - add a dummy rich:tree tag to the page. e.g:
>   <rich:tree id="dummyTree" rendered="false" toggleType="client"/>
> - remove c:if (which is no alternative in my case)
