I started working on AT for Flex last month. As of now it is supported only Quick Test Professional from Mercury and for the IE browser on Windows.
A preview release happened yesterday.
I have been working on bug fixing for few weeks now and moving on to supporting nested apps/RSLs from today.
I am new to RIA, Flash and internet. So I need to understand how to build RSLs and use them before I can start implementing/testing support for them in AT.
I found some material on RSL written by Roger here . But it is for Flex 1.5 and I couldnot make much use of it except for the information and advantages of RSL.
So I started using the FlexBuilder Beta 2 to build the apps. After some initial hickups I was able to build a shared library and a mother app using the lib.
