I'm dipping my toes with the new Field Sets (FS) feature and I really like it. It will reduce administration coding tremendously if you are a heavy VF user.

My problem is that I want to display different field sets based on the rendered attribute. The idea is that you have a master FS and clone variations that allow for context treatment in a page. The help text for the <apex:repeat > component inidcates tha rendered is a supported attribute.

My tests suggest that it is not yet supported. I set up a test object to test the feature:

I setup 2 FS called FS1 and FS2 where FS2 is a clone of FS1 but with an extra field.

The first 2 page sections make sure both field sets display.

The next page sections (3) checks that they display if incuded in the same page section.

Page Section (4) is to base a rendered on a boolean

"Field Set FS2 only if Field 1 true"

The final Page Section is a straight forward test: 

rendered="false">

  </apex:pageBlock>

 In all cases the rendered attribute is ignored. Since it is a beta release I'm inclined to think it is a feature bug? Anyone else seen the same issue?
