    [ https://jira.jboss.org/jira/browse/JBSEAM-4641?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12527374#action_12527374 ] 

Steve Wells commented on JBSEAM-4641:
-------------------------------------

One other observation - when hardwiring the ID's i.e. "id="xyz" the IDs are still tied to JSF generated IDs in the generated HTML:

id="j_id138:0:xyz" name="j_id138:0:xyz"

>             Project: Seam
>          Issue Type: Bug
>          Components: EL, JSF Integration
>    Affects Versions: 2.2.1.CR1
>         Environment: Linux Server Side, Windows + IE 8 Client Side
>            Reporter: Steve Wells

> When specifying an ID for a control (seems to affect all / near all) using an EL expression, it doesn't matter what the EL expression method returns, the following exception is generated.
> EXAMPLE
> <h:outputLink value="http://www.jboss.org" id="#{x.id}">LINK</h:outputLink>  <!-- the x.id() method returns "123", etc. -->
> <h:outputLink value="http://www.jboss.org" id="XXXX#{x.id}">LINK</h:outputLink> <!-- the XXXX prefix doesn't even get it to pass -->
