oookay. So I have setup a flash MovieClip with a scrollpane in it, and another MovieClip that run’s a FOR loop to create a list of buttons dynamically.

I have the script pull the dynamic MovieClip and load it as a source to the scrollPane but the scrollbars are not appearing. To make sure that the scrollpane was working, I added an event listener to the scrollpane that when I clicked it it will run scrollPane.invalidate() and the scrollbars will pop on.

So here’s my problem/question: If i’m dynamically adding a listMC to this scrollPaneMC, how do I get listMC to throw the invalidate() to the parent scrollPaneMC?

Here’s another way to look at it:

ROOT add’s a child scrollPaneMC. ScrollPaneMC uses listMC as a source from the library. listMC run’s its FOR loop and dynamically creates a list and appears in the scrollPaneMC, but no scrollbars.

I really hope I’m explaining this properly and I thank you for your time!
