Subject Re: Proposal for contributing code from GraniteDS
Date Mon, 24 Sep 2012 13:46:20 GMT
Hi Franck,

I think it would be great. I was in the way to make some
implementation some time ago since flex view validation is problematic
when you try to use MVC but I never get to far. In flex the problem is
that validation and view controls are dependent and it would be great
to have bean validation in order to validate data and have real
separation from the view. This brings the problem on how to show the
errors in controls to let the user now about a failed validation. I
suppose that is solved in GDS.

So I think bean validation would be a great improvement in flex SDK
and annotations would make it more usable.

For BigDecimal and others classes could be great as well, but I don't
have clear how could be donate to sdk...maybe it could go to an
extension package or something like that and get some externalization
base implementation...
