We have a big Flex 3 project with 30 developers. I need to present benefits/costs of upgrading from Flex 3 to Flex 4 and I can't seem to find existing data on Google. I assume I am not the first to do this. Our application is RIA app so it's not a video/custom component heavy.
I have these benefits:
1) Right to left native support
2) Smooth Scrolling
3) Two way binding
4) FXG
5) Better state model
I need more data about the following:
1) Spark - What are the actual benefit from Spark components? Are they faster? How much faster compared to halo? easier to use?
2) It mentions Here and in many articles that Flex 4 has compile speed improvements. Are there any benchmarks?
I see Here a 60% increase, but not sure if it's the SDK version with Flex 3 compatibility or not.
If anyone here already wrote a report like this, or has upgraded and can report real benefits or other ideas, please share them.
It depends on the nature of your project.
Do you need better data validation / custom formatters?
Do you update your design often?
Are you in need of not trivial layouts?
Would you like to use Globalization API introduced in Flash Player 10.1?
Are you ready to acknowledge that nobody will ever fix existing open issues at Halo mx components set?
