Great news to the Flex community that Cairngorm is now open-sourced. I can only hope for more great things to come. Having completed my first project using Cairngorm, i would certainly recommend it to anyone who is using Flex in their projects.

Here’s a video about customising your own skin for your Flex controls. Simply cool! This feature is certainly something i am looking forward to.

I have two different Flex apps, one compiled with Flex3(i call this F1) and the other compiled with Flex2(call this F2). Both are accessing the same endpoint.

Everything works fine when you access in the order of F2 and F1. Hell breaks loose when i access F1 followed by F2. I noticed that F1 creates a JSESSIONID cookie on my browser and deleting it allows my F2 to work.

My guess is that a bug was fixed between Flex3 and Flex2. Now i have to push up the schedule for a version upgrade for F2 app.
