[jsf][gravel][facelets][tobago] How can we define a comp id namespace?

[Zied Hamdi <ja...@gmail.com>]

Hi,

I have a problem with reusability of components: I have many jsf template
pages that I use everywhere throughout my app. The problem is that when
I define explicitely the ids of my UIComps, name collisions occur.

The question is: is there a way to define a sort of "namespace component
holder" so that my components have ids of type *page:namespace1:namespace2
:realComponentId*
this whould be the id of a component like this:
<tc:page id="*page*">
   <f:namespace id="*namespace1*">
     <f:namespace id="*namespace2*">
      <tc:out id="*realComponentId*"/>
    </f:namespace>
  </f:namespace>
</tc:page>

To be more explicit about the problem: Today I'm passing in every include a
parameter (idSuffix) that I append to the id:

*clientPage.xhtml*
<ui:include src="compPage.xhtml">
  <ui:param name="idSuffix" value="clientPage">
</ui:include>

*compPage.xhtml*
<tc:in id="personsTree#{idSuffix}" />

what is even more tedious is when I use another template in the included
template itself. I must pass idSuffix through :
  <ui:param name="idSuffix" value="#{idSuffix}">


So does a namespace feature exist in standard JSF maybe tobago, or
maybe gravel?

Thank you Simon,

I'll remove all my ugly code with id construction :-).

Yes, it's called f:subview. Just wrap that around every include
statement.

Interestingly, I thought that facelets did this automatically, and that
f:subview was only needed for jsp includes. But obviously I'm wrong..
