Component within component in Flash Catalyst?

Hello All,

I am creating an interactive timeline in Flash Catalyst. One feature is to have boxes of text become visible after clicking on a button.

One of the boxes of text is pretty long and I want to have it be scrollable text. I have created a scroll panel within a toggle button, but the text region, when visible, acts the same as the underlying button.

Can Flash Catalyst CS5 handle components within components?

If so, can anyone help me to find a solution to the above-described issue?

Thank you for any suggestions,
