The index is generated when a component is assigning children. The index is
just incremented for each child. It's not related to the renderId property.
The renderId property for HTML views is generated and you don't have control.
The significance of the renderId in in defining a complex component in the XML.
The renderId defines the sequence and the signature for inheritance.
<component jsfid="mypanel" extends="gridPanel">
<attributes>
<set name="columns" value="2"/>
</attributes>
<element renderId="0" jsfid="space"/>
<element renderId="1" jsfid="city"/>
</component>
<component jsfid="anotherpanel" extends="mypanel">
<element renderId="0" jsfid="cityLabel"/>
</component>
The index int is used because when a view is restored, components that were
marked as transient are created where other components are just restored.
Transient components makes a difference when using client side state saving.
In html views, tokens that are not directly bound to a jsfid or implied mapping
(form, a, input, select...) are inserted into the component tree as "verbatim"
components. This translates into a outputText with the isTransient attribute
set to "true".

I think the problem is that you have two jsfid attributes (second overrides the
first). Try using the "clayJsfid". This is a new feature added a few weeks
ago. Otherwise, I don't see the problem but I only got half your mail due to
my webmail interface not escaping.
If that doesn't fix the problem, please create a buzilla ticket and attach your
html view.
