JV,
From what I understand, setting component ids dynamically through EL is
disallowed.
There has been discussion of this, which can be found in the archives.
Here is one example, see [1](tiny url) or [2](full url).

Regards to all,
I haven’t been able to establish different id’s for a HTMLCommandLink
components inside a list.
I have tried the following 2 scenarios with the respective result:
1. <ui:repeat
value="#{toolTabBean.toolbarElementList}" var="toolbarElement">
<td>
<t:commandLink
id="#{toolbarElement.id}" forceId="true"
action="#{toolTabBean.toolbarElementActionDelegate}" styleClass="link">
<h:graphicImage
value="#{toolbarElement.imagePath}" alt="#{toolbarElement.altText}"
title="#{toolbarElement.toolTipText}" styleClass="borderLessImage"/>
<h:outputText
value=" " />
<f:param
name="toolElementId" value="#{toolbarElement.id}" />
</t:commandLink>
</td>
</ui:repeat>
RESULT: I get the exception: java.lang.IllegalArgumentException: component
identifier must not be a zero-length String
at
javax.faces.component.UIComponentBase.isIdValid(UIComponentBase.java:1034)
at
javax.faces.component.UIComponentBase.setId(UIComponentBase.java:274)
………etc…..

2. <ui:repeat
value="#{toolTabBean.toolbarElementList}" var="toolbarElement">
<td>
<t:commandLink
id="#{toolbarElement eq null ? 'trialId' : toolbarElement.id}"
forceId="true" action="#{toolTabBean.toolbarElementActionDelegate}"
styleClass="link">
<h:graphicImage
value="#{toolbarElement.imagePath}" alt="#{toolbarElement.altText}"
title="#{toolbarElement.toolTipText}" styleClass="borderLessImage"/>
<h:outputText
value=" " />
<f:param
name="toolElementId" value="#{toolbarElement.id}" />
</t:commandLink>
</td>
</ui:repeat>
RESULT: All the rendered anchor (<a>) elements in html end up having the
same id: trialId

I need to be able to have each commandLink rendered with a specific Id as in
specific situations I reference certain commands through javascript
code…making use of their ids.
Any idea on how can I accomplish this?
Thanks and regards,
JV
