A long awaiting post, Yahoo! Open Hack Day 2010, Bengaluru. This happens to be my longest stint with coding. For those of you who dont’ know, Open Hack Day is 24 hrs – to build an innovative application on-spot, overnight, with unlimited caffeine and Red Bull’s and glowing laptop’s all around – Not to mention the smell of Geek Air :). Thanks to Twitter, I managed to make it to the 13th Open Hack Day.
If you are wondering why am I bragging about ‘Hacking’, your probably mistaken.
Here is a small piece of code I wrote to demonstrate Interacting with a Command, through an Event while using a Cairngorm Framework.
The application connects to a WSDL webservice via Flash Builder 4 Data/Services to validate an Email address against the Email Server. Doesn’t work well with domains with a ‘Catch-All’ email address though !

But isn’t all this going against the very purpose of using the Cairngorm architecture?
Why not have parameters passed to a Cairngorm Event every time its dispatched, and stay away from mixing C with M and V in a MVC Framework?
This post explains how you pass parameters to a Cairngorm command at runtime, via a Cairngorm Event.
