ComboBox problems when in a MovieClip loaded at runtime

Question

Hello,
I hope someone out there can help me with this problem: I
have a ScrollPane that contains a MovieClip that to which I attach
several other MovieClips at runtime in response to user inputs
using attachMoveClip() (both MCs are in my library and set to
export for actionscrip in first frame). Each of those MovieClips
contains a ComboBox.
At runtime, I attach the MovieClip containing the ComboBox,
then I set the dataProvider property for the ComboBox to a list
(Array) of data/label value pairs. I then try to set the text
property of the ComboBox to a "Please select a value" message and
then I add a couple of listeners.
Setting the dataProvider property sort of works: the ComboBox
displays the proper dropdown list when clicked, but nothing happens
when I select an item from the dropdown list - i.e., the selected
value doesn't display in the ComboBox's TextField.
Setting the text property doesn't seem to work: the value
doesn't display in the ComboBox's TextField, but oddly, if I trace
the ComboBox's text property, it outputs the correct message.
Also, none of the event handlers work at all.
I tried all of the same code on a ComboBox that isn't created
dynamically, and it all works.
Here's the code. The first set of code is the part I need to
get working. It sets up the ComboBox after the MovieClip it is
contained in is attached to the parent MovieClip. The second set of
code was my test code to see if this worked on a ComboBox that
isn't created at runtime. It all works properly.

Most likely the Combobox isn't fully loaded yet. In your code
check if a property of the cb is undefined using an interval and
proceed with the code when the property is defined.
