Flex sdk 4 , spark components

[sims11tz]

Hey , when do you think it would be smart to develop with the 4.0 sdk and using the spark components in Flex. I'm pretty sure that the publicly released flash player 10.0.32.18 can handle a sdk4 compiled .swf My boss really wants to port our player 9 flex apps to player 10 and it is surprisingly hard to find data on actually coding for player 10. There are a ton of sites that say what is new in player 10 but very few that actually talk about the code.

Thanks for any thoughts!!!

FP10 penetration rates are high enough to warrent it being a release target.

Flex 4 sdk - including spark and related aspects - is not so different that someone comfortable with <4 will have a big problem re-orienting themselves. Besides, support for mxml 2006 is built-in - you can port something very quickly, and look to incrementally revise your code base.

The SDK obviously has bugs, but Beta 2 is stable enough and does look it going to require fundamental rewrites come the final release. Again, if you are confident with the framework, Gumbo is well past the point of regular fire fighting - in my experience at least.

There is some information out there on using Gumbo, but as you say not a whole load; livedocs for Gumbo is a little sparse, there are some blog entries, etc. Still, if you have any specific issues, post here...

One other thing - all the spark and older halo components are not actually built into flash player, they are MXML/AS classes that get compiled in to your SWF and run by Flash Player (which is why Flex SWFs are usually so large as the entire UI handling system is added to your SWF). Unless the spark components use any FP10 specific stuff (admittedly I don't know the answer to that!) there's no reason the spark stuff won't run on FP9.

You might patch the gumbo framework to run on FP9, and you might extract parts of it and add them to sdk 3, but these are not casual adventures, and do not have any real benefit...
