Flex: force focus on parent change

I was trying to solve a problem of resetting a focus if the parent changes. I had different buttons that show the same .mxml-form but with different data. The problem was that I needed the focus to be on the first date-field whenever the form is shown so that the user can begin typing data right away.

Flex dynamic ComboBox

I’ve recently¬† come to an issue where I needed a ComboBox in Flex with dynamic dataProvider and couldn’t work it around for a while. There is a bug in SDK 3.5 so that a dropdown list in a combobox shows old values after change of dataProvider. To overcome a problem you need to bind the dataProvider.
