Subject [jira] [Commented] (MYFACES-3168) Bound attribute values resolve to NULL during PreRenderViewEvent for nested composite components
Date Thu, 14 Jul 2011 12:33:00 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-3168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13065209#comment-13065209

Kennard Consulting commented on MYFACES-3168:
---------------------------------------------

Hi guys,

I have stumbled across something very similar to this issue, and have slightly modified Matt's
jsf-testing.zip to demonstrate.

Basically Matt was using his own composite component as the 'outer' component. If he added
pushComponentToEL to it, as Leonardo suggested, he could fix his issue. But what if the 'outer'
component is out of your control? In my case it is an h:column. There is no opportunity to
call pushComponentToEL on the h:column, and calling it on the 'inner' component has no effect
(as is to be expected). Is there a workaround for this case?

Regards,

Richard.

> When nesting custom composite components, any data bound attributes (eg #{someValueExpression}
) will resolve to null during the PreRenderViewEvent. This only occurs on the second level
or deeper nested component (the top-level component in the page works fine).
> This same issue occurs on JSF RI 2.0.4, 2.1.x, 2.2.x
> I have an eclipse project for upload that reproduces the problem.
> I have no cause for the issue at this time.
> Cheers,
> Matt
