I found that myComboBox is not initialized when onEditStateEnter() is
running, so I could use workaround like:
protected function onEditStateEnter() : void {
if (myComboBox.initialized) {
onEditStateInitialize();
} else {
myComboBox.addEventListener(FlexEvent.INITIALIZE, onEditStateInitialize);
}
}
Are there any better solutions? :)
