[jira] [Commented] (MYFACES-4006) EL in Composite Component Attribut gets no access to bound params from

["Leonardo Uribe (JIRA)" <de...@myfaces.apache.org>]

    [ https://issues.apache.org/jira/browse/MYFACES-4006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14743902#comment-14743902 ] 

Leonardo Uribe commented on MYFACES-4006:
-----------------------------------------

The reason why this happens is ui:param relies on serialization to pass the right value. Since ui:param is evaluated at build-time, the value is serialized so it can be later user in render-time and keep things consistent. If the object does not implement Serializable, no value is stored in the state and the result is the method is called with null.

>From algorithm perspective there is nothing else we can do, so I'll close this one as not a problem.

>          Issue Type: Bug

>         Environment: Fedora 22, TomEE 1.7.2

> I have a facelets snippet that uses a composite component:
> >>> index.xhtml
> <ui:include src="foo.xhtml">
>   <ui:param name="bar" value="baz" />
> </ui:include>
> >>> foo.xhtml
> #{myBean.someMethod(bar)} calls someMethod with "baz"
> <sc:someComponent someattribute="#{myBean.someMethod(bar)}" /> calls someMethod with null
> I guess that the EL in composites is evalutated too early or the binding is not submitted correctly.
