Thanx alot for your reply! I tried that and the dynamicId tag works as long it
has no child elements. But when I try this:
<jsfutils:dynamicId value="#{field.id}">
<tr:form>
<tr:selectOneChoice
required="#{field.required}"
value="#{genericFormBean.formDesc.modelMap[field.id]}"
<f:selectItems
value="#{genericFormBean.selectItemMap[field.itemList]}"
/>
</tr:selectOneChoice>
</tr:form>
</jsfutils:dynamicId>
I am getting this Exception:
java.lang.NullPointerException

and the DynamicIdRenderer is never called.
I am using Trinidad 1.0.11 (JSF 1.1). We have no option to switch to JSF 1.2
since we stick on JBoss 4.0.5 :-(
Best Regards,

Betreff: RE: Component id doesn't support EL?
Not really, I believe it's in the JSF specification that the ID is not allowed
to be dynamic. I actually wrote about this on my blog (which is not very
popular since I don't really promote it much), but you can check it out
http://rossner.wordpress.com , I think it's actually the most recent one (which
is quite old), it's blocked from my office so I can't even check it (damn
websense), but I do have a "sort of" workaround for this, it won't work in all
cases but maybe it will help you.

Subject: Component id doesn't support EL?
Hello,
I tried to use the EL to set an id on a <tr:selectOneChoice> component:
<tr:selectOneChoice
id="#{field.id}"
required="#{field.required}"
value="#{genericFormBean.formDesc.modelMap[field.id]}"
<f:selectItems
value="#{genericFormBean.selectItemMap[field.itemList]}"
/>
</tr:selectOneChoice>
But I keep getting an IllegalArgumentException. So it seems like EL is not
supported for an ID, event the documentation says so.
Is there a workaround for that?
