Have you tried it with Flash CS3 (version 9) ?
May be it is because the components of version 8 are using some code that Flex doesn’t like.

@Alejandro, True, but Apollo must work with all prior versions of Flash. I’m sure this is just an Alpha bug. I just wanted to draw attention to it. As new Apollo versions come out I’ll test to see if this works.

Combo box behaves differently when it is in an SWF embedded in another SWF, much of that has to do with focus management. Have you tried to embed your SWF in another SWF 8 or SWF 9 movie (other than Apollo)?

When I was working in the similar scenario, I have tried the following code

this._lockroot = true;
_level0.focusManager = false;

in the first frame of the movie where a combo box would be placed, and it seems to work fine. I don’t know if this would help solve Apollo’s quirk you mentioned.

@Tangent, That was an excellent suggestion. Unfortunately it didn’t work. Fortunately I don’t need this to work. It was an ancillary deliverable for a usability test that’s already completed now.

Thanks for the suggestion. I’ll be sure to post if the next release of Apollo fixes this.

Try to put id attribute in the same line that you opened the tag. It is a reccomendation from Adobe.
