Generating Dynamic IDs

Question

Hello All,
I need to generate dynamic ids on the <h:commandLink.
However if i put something like
<h:dataTable id="items" value="#{FormBean.resultList}" var="listItem" >
  <h:commandLink id="#{listItem.recordId}" action="some.page" actionListener="#{someFormBean.someMethod}">
  </h:commandLink>
</h:dataTable>it throws
java.lang.IllegalArgumentException: #{listItem.recordId}
        at javax.faces.component.UIComponentBase.validateId(UIComponentBase.java:454)Basically, i need to generate a list of results and each row in the list should have a hyperlink which will open the row details. I was hoping to get the rowid in the actionListener method by using event.getComponent().getId().
Any help is appreciated
Thanks

Thanks for the reply. I tried doing that and couldn't get it to work. I looked at the requestMap and it shows something like the following
subview1:subview2:_id15:_idcl=subview1:subview2:_id15:items:0:_id18
So it does have the correct row number and items is the "id" of the datatable, however how do i get that row number using the "var" name as you suggested ?
Moreever the component which maintains the row number --> record id mapping may be different from the component which handles the event. So i may have to add some extra logic in the event handling component to retreive the recordid, based on the row number.
Another alternative which worked fine , was to include a param tag (containing the recordid) inside the command tag. So the event handling component can retrieve that param directly without relying on any other component. I am not sure if this is the recommended way.
