Flex and its schizo ComboBox

Posted by Shane O'Sullivan on February 1, 2009

I’ve been working on Adobe Flex quite a lot recently (not by choice – those who keep my bank account from emptying told me to), and while some features are quite nice, the one thing that drove me absolutely crazy was the ComboBox.

It picks strangely arbitrary times to lose its value, changes the data that it is bound to on a whim, and generally makes your application about as predictable as a ferret with rabies.

Of course we were able to fix many of the problems by sub classing and overriding many of the functions, but this should not be necessary.

Does anyone know of a good open source implementation of a Flex ComboBox?  If so, please Please PLEASE leave a comment pointing to it.

    We’re also having some issues with the Flex ComboBox (mainly performance issues). Can you post your subclassed combobox by any chance? We’d love to compare it and see if it changes our performance issues.

  2. Sorry, that code belongs to my company and is not open source, so I can’t post it.
