ok, i figured out a way to do what i want to accomplish - and i think i
mislead (myself included) the first time around (apologies).
I think this will work for what i want:
> <component id="boxesList" type="Foreach">
> <binding name="source" value="htmlBoxesAsStringsList" />
> <binding name="index" value="boxesIndex" />
> </component>
> .....
> .....
> <component id="textDisplayed" type="CustomComp">
> <binding name="customBinding" expression="method(boxesIndex)"
/>
> </component>
I never really wanted the value binding of the Foreach in the first place.
I'm simply going to try to wrap the CustomComp in the foreach.
Much simpler than i planned.....
thanks E,
marc

Foreach where value is another component(Document
link: Marc Smith)
e,
My aim is for something like this:
> <component id="textDisplayed" type="CustomComp">
> <binding name="customBinding" expression
="valueBasedOnIndex(components.foreach.index)" />
> </component>
I want each iteration to come up with a completely different component, and
extract from there.....
I'm not too bent on using the index, if i can do it another way.

Hahahah. Sorry dude. I totally misread your original post.
So, why do you need a different component for each index?
