So I am here struggling for hours (at least it looked like it was hours!) trying to figure out why my combo box wasnt working.
The Basic scenario is that I created a CB in a child movie for later being loaded to a parent movie.
->Parent
–>Child < -with Combo Box
Well, when you load the Child movie into the Parent movie you expect it to work whitout a problem right?… WRONG! some kind of bug or problem or whatever for some reason the Combo Box wont work, why? who knows.
Doing a light search I found out that in order for the Combo box to work on the Parent Movie you need to have a copy of the Combo Box component in the Parent movie even though you are not going to use it directly within the parent.
That’s a lie! you might think (or at least that is what I thought) but in reallity it works.. now this is my set up:
-> Parent < -copy of Combo Box Component not being used
–> Child < with Combo Box used
Weird.. but it works, just in case someone is looking for the answer

i followed the procedure. the combo box now shows in the parent but doesn’t allow me to choose items from the dropdown. do you have any solution to this?

No really, I would need to see your set up or at least see how you are linking to the CB

Amazing. I had a problem w/ the function: comboBox._focusrect=false, working in my child MC but then not working in my child after it was loaded into the parent. This was the only solution. Thanx

You need to create combobox with Actionscript if you want to let work it properly…
