ValueExpressions in id attribute return null

[ziphyre]

Hi,

I'm using seam 2.0.2 with facelets 1.1.14 and richafeces 3.2.1. My problem is I can't generate dynamic ids with EL.
For example:

<s:link id="message#{msg.id}" styleClass="message#{msg.Id}" />

results in:

<a id="message" class="message45" />

As you can seen #{msg.id} is not null, since it evaluates to 45 in styleClass attribute.

Some people have reported that they can and do generate dynamic ids with facelest 1.1.14 and JSF1.2

I don't know how to troubleshoot this, since there is no error.
Any help would be much appreciated...

Thanks

Hi Marco,
i have a similar problem. What i wanna do is generate an input field with dynamic id, but:

<h:outputText value="#{obj.id}"/>            <- correctly rendered, e.g. 'DE'
<h:inputText id="input_#{obj.id}" .../>      <- just rendered as 'input_', not 'input_DE'

I know it's been a long time ago, but can you remember what was the solution?
Maybe it isn't possible at all cos the id is rendered while rebuilding the component tree, and the object is not available that early?!?

Another topic
http://www.seamframework.org/Community/CreatingDynamicId
also says dynamic ids are not possible, but if you say it is, did you find out how the guys managed it?

Thanks a lot, best regards
Flo

Hi Flo,

Unfortunately I don't have any solution for this, but also it's been a long time I quit working with Seam. Maybe some other people can answer your question.

The JSF specification doesn't allow dynamic id's of the components. With id as EL you can break the view.
