Yeah, it wasn't personal Alex. I guess I just felt like giving some commentary/feedback from the developer point of view. Sorry if it was taken the wrong way.

I say this only to point out the different perspectives between a flex framework engineer and an average or beginner flex developer. Sure, the power of flex is that you can always roll your own; when necessary. All for that!!! The problem though, is that this may be too much to ask from a developer with a deadline. Before flex, I came from the Microsoft camp. I absolutely appreciate the freedom that flex affords, to extend the framework and/or create components from scratch. But, the built-in properties and styles that flex offers is not quite as comprehensive as what I was previously used to. That being said, I'd love to see the best of both worlds in the next generation of! flex. I guess it boils down to the budget and scope of each release of flex. Of course, the framework can't account for every possible use-case. However, there are quite a few common functions and styles, that could be considered to be included. I've had to do something like "all" or "none" many times with a ComboBox. For a cleanly coded application, I'd much rather just be able to set a property, like prompt (but more like reset), instead of adding a sub classed control or hacking a solution through the dataProvider. Just .02 and a pseudo rant. :) > > -TH > > --- In [email protected], Alex Harui aharui@ wrote: > > > > An example of such on my blog > > > > From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Tim Hoff > > Sent: Monday, November 03, 2008 2:08 PM > > To: [email protected] > > Subject: [flexcoders] Re: adding (none) option to comboboxes > > > > > > Hi Derrick, > > > > The ComboBox prompt will not solve your problem here.
