Add Dynamic Content to ScrollPane

Question

I have created a Address Class that uses Remote Hosting to
get addresses for site locations and creates the appropriate
listings in a MovieClip.
I am trying to use this class as the source for a scroll pane
inside another movie clip.
I get the site locations to show up in the scrollPane but
they will not scroll.
I believe I need to pause some how in the constructor until I
have all the site addresses created.
Anyone know how I would do that or know how to get the
scrollpane to scroll.
Thanks
Adam
Here are some snippets

scrollPane.scrollDrag = true;

scrollPane.y = -180;
scrollPane.source = new AL_Addresses;
addChild(scrollPane);
stop();

I don't see it in your code anywhere, but maybe you removed
it (or I'm just not seeing it). You should update it only after you
have filled the scrollpane, not when you add the scrollpane to the
stage. It is not likely the scrollpane is filled by the time these
two lines are processed, especially if you are loading content from
a server...
scrollPane.source = new AL_Addresses;
addChild(scrollPane);
