Steve,
Do me a favor and test something out. Make the items Array an
ArrayCollection on your own.
Here is the gist: When you pass an Array to either ComboBox or List it
makes an ArrayCollection out of it for the purposes of binding. List
does something slightly different in that it stops listening to the
existing collection first. This may mean nothing at all.
However, I am concerned that you are getting lucky on the timing of
the ComboBox. This is just a guess, but try it and post back some code
if it does not work, I will be glad to look at it.
