In that case I would create a component that had two states, one radio and one button, and repeat that, passing in the entire currentItem in a setter function, and set the state based on the passed in data.
On the filter, are you asking for an e4x expression? One tip is that in an e4x expression, you can use a function in place of in-line expressions, pass a ref to the current node into the function, do whatever logic and return a Boolean if the node should be included. Are all the ids 1 or 2 chars only?

However, I'm trying to write a Filter function. This function will compare an ID and return a subset of IDs. For example, an ID of 1 will return IDs with 11, 12, 13; an ID of 2 will return IDs with 21, 22, 23, etc... How do I compare IDs as strings to return what I want? Any tip in the right direction is greatly appreciated. --- In flexcod...@yahoogro <mailto:flexcoders%40yahoogroups.com> ups.com, "fumeng5" <fume...@...> wrote: > > Hmmm...I didn't know about the Repeater component, that's quite useful.
