ComboBox acting funny between keyframes

Question

There are two keyframes, "A" and "B", in
my movie. A ComboBox is present on both
keyframes with the same instance name.
Items are populated on Keyframe "A". Then I do
a gotoAndStop("B"). If the position of the
ComboBox is shifted, then none of the items would
show when the ComboBox is open. However, these
items are still there when I check them by getItemAt()
method.
If the position of this ComboBox is not moved,
then I could see all the previous items in it.
What's going on, and how could I fix this problem?

Answer 1

I wouldn't have two keyframes with the combobox in it. I
think that will be trying to replace the existing instance from
frame A in frame B.
I would have the second frame as a frame, but not a keyframe.
If you want to move the combobox in frame B from frame A,
just do it by code:
if the name of your comboBox is myCombobox...put the
following code on frame B (after making frame B just a regular
frame and not a new copy/instance of the combobox).
myCombobox.x +=100;
myCombobox.y +=100;
Try doing it like that, see if it makes a difference. (I
don't use the timeline much so this is just a guess at what might
work)
