Question about letting my old widget (2.3 versin) pointing to new flex API 2.4

LeiZhou — Mon, 12 Sep 2011 13:48:37 GMT

I tried to point my old widget (2.3 versin) to new flex API 2.4 --I add new swc file to the lib folder and delete the old one.

But it throws ActionScript errors as the following: I was wondering, is it possible to let 2.3 widgets pointing to Flex API 2.4? Thanks!

Steven,

No the NavigationWidget was updated to use Skins in 2.4 so it is not backwards compatible.

Thanks a lot! I find the NatigationSkin.mxml file, and change the <mx:VSlider> to <s:VSlider>, then it works.
