Mihai Chira commented on FLEX-28291:
------------------------------------
I attached a project which can reproduce a version of this bug (error pasted
below). I know for sure that it can be reproduced through normal interaction
with the ComboBox (and probably very unlikely timings of collection refresh()
calls) because we got it as a bug report from two of our users. But this is the
only way I could find to reproduce it in a test project in a way that's vaguely
realistic (i.e. it's very unlikely that the user will type exactly in the right
frame, and that the developer will have a listener to UPDATE_COMPLETE on the
ComboBox).
