I wonder if this might somehow be related. item was a UIData interator var.

I made a new test JSF application to try to recreate the problem, in order to
publish on this forum. Instead, I got to carefully review all the pieces and
in the process solved it.
I needed to add the class (representing a row) as a managed bean in
faces-config.xml with scope of "none":
<managed-bean>
<managed-bean-name>item</managed-bean-name>
<managed-bean-class>whatever.the.class.is.called</managed-bean-class>
<managed-bean-scope>none</managed-bean-scope>
</managed-bean>
Without this, you get the "Base is null" error.

Yes, I do have two different beans, but the code inside the 'rendered' block
is getting evaluated even when the condition is false.
To dynamically change the component tree based on internal structures, it
appears that constructs like <ui:repeat> / "rendered" / <c:forEach> are not
working too well. I am having better success by binding a h:panelGroup to my
Java code, and from Java code, programmatically manipulate the tree.
However, it is not as convenient as scripting.

Hi Venkat!
If you have two pulic classes then there must be
two different beans in your xml file, say circle and
rectangle. In first panelGroup use
rendered="#{circle.objType == 'circle'}" and in second
one use rendered="#{rectangle.objType ==
'rectangle'}". It seems as if in your code rendered
property is working as expected.
