Re: [flexcoders] Combobox and XML and label functions I cannot seem to get labels to show up!!

[Mike South]

Joe:

Here is a complete mxml file using your code (I don't know if it will
display correctly, I'm using gmail's "plain text"--apologies in
advance if it's mangled).  It works fine--the combo box shows the demo
and demo2, and after the change it shows post_change_demo and
post_change_demo2 (for that you need the Bindable--otherwise the combo
box won't see changes to dataSetColl.

Maybe you can give us more detail about how you have it set up?  I
don't think the problem is with the code, but maybe stuff is outside
the package, or you don't actually have the value assigned to
dataSetColl that you think you do?
