List of complex statefull components : HELP!

[valkl <ma...@tapestryforums.com>]

I need to make a list of complex items. Each item contains 2 (two) PropertySelections (Master-detail) and some Input fields.

First time I think to make a component for item and reuse it in For cycle.

But I did not find a way to specify a List of components - only direct one.

Now I have only one idea how to assemble together List of components on one page - implicit component declaration like


    
    


but I have to transmit to each item component hudge data set: Item, selected Master value, list of detail objects to show in detail PropertySelection (later PS).
Also I have to make detection is Master PS value changed to change list of detail objects OUTSIDE the component - in a place where I have information of outer data. 

All this looks like a NON-object approach to me: elementary incapsulation is broken because we use ItemComponent as a stateless object

Can you give me a clue in DESIGN and implementation of such task cause I really like TS for property binding, but now for a simple problem I should begin a great investigation... It should be iniuitive... Even for JSP it's easy to understand how to do my task quickly...

Let me repeat: problem is to find a good OO-solution when a component :
1. transmit to outer component only information they should receive, NOT inner state info
2. Inner logic like master-detail operation and selection handling is processed INSIDE a component code.

So, outer code that use a component will see only a correct result of component work.

PLEASE help, I need a reliable and supportable solution soon and existance of a good solution is a matter of usage of TS in a great project.
I really like TS and want to use it, but using NON-OO aproach is a suiside.  :)

Do you need the For component maybe to iterate over a list and render in 
each iteration the component?
