Datatable and ExtendedDatatable evaluate value attribute even if rendered=false
-------------------------------------------------------------------------------

                 Key: RF-11382
                 URL: https://issues.jboss.org/browse/RF-11382
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-tables
    Affects Versions: 4.0.0.Final, 4.1.0.Milestone2
         Environment: Fedora 15, Glassfish 3.1.1, CDI (Weld)
            Reporter: Frederick Kämpfer


In Richfaces 4 both datatable and extendedDatatable evaluate the value attribute even when rendered is set to false, even though it is not necessary. This makes it hard to achieve performance by trimming parts of the view tree. The built-in h:dataTable behaves correctly in that case.

To reproduce simply try this snipplet:
{code:xml}
<h:form>
     <rich:dataTable value="#{myBean.property}" rendered="false">
      </rich:dataTable>
</h:form>
{code}

Side note: The reason I'm posting this is, that i want to embed a rich:dataTable in a ajax loaded rich:togglePanelItem which is loaded on demand. Probably fixing the "render" problem will also make the dataTable lazy-loadable when switching to the corresponding togglePanelItem.

I hope this is no duplicate, I only found RichFaces 3 issues mentioning this problem.
