EL expressions not evaluated in id attribute ?

[fdegrigny]

I have a JSF page with the following code :

<rich:dataTable value="#{pageCtrl.colsToDisplay}" var="col" >                                   
       <rich:column id="lab_#{col.propName}" >
             <h:outputLabel id="label_#{col.propName}" value="#{col.label} :" for="#{col.propName}_input" />
        </rich:column>
         <rich:column id="col_#{col.propName}">
                  <h:inputText id="#{col.propName}_input" value="#{pageCtrl.selectedBean[col.propName]}" />
         </rich:column>                      
</rich:dataTable>

But the #{col.propName} expression seems not to be evaluated in the IDs attributes. So I obtain the following error message in console :

"22 janv. 2010 08:47:39 com.sun.faces.renderkit.html_basic.HtmlBasicRenderer getForComponent
ATTENTION: Unable to find component with ID EAN_input in view."

But, if the expression is put directly in the page it is evaluated.

Is it a bug or I miss something important ?

Hi Frantz,

No, it's not a bug, but specific of UIData-based iteration components. Find out more by searching "ui:repeat vs c:forEach".

Ok, but how I can generate the correct "for" attribute value for the <label> tag inside a dataTable's row ?
