João,
Thank you so much for the quick reply. This binding thing takes some
getting use to.

> Anyway, I'm fairly new to Flex and am working on a project using the
Cairngorm framework. In the project I have a form that is bounded to
a sharedObject in order to save the user's responses in case they do
not complete the form in one sitting. When the user returns to the
form, I reload the fields with the values stored in the sharedObject.
> All works fine with text fields and check boxes. The problem comes
with a couple drop-down fields. Basically, when the form is loaded I
call back to the CF server to retrieve a list of values to populate
the drop-down, and set an array variable in my ModelLocator, which is
bound as the data provider to the drop-down. The problem I have is
that I can't figure out how to set the selectedItem after the
drop-down is populated. I tried to create a function that accepted
the ModelLocator Array and set it then, but that does not seem to
work. Anyone else have any suggestions?
