I just saw that Universal Mind Cairngorm extensions for Flex are now set up on RIAForge (thanks Andrew).

We have been using the UM Cairngorm Extensions at Straker Interactive (where I work) for ZoomFlex since about six months.

One of the features that I really like about the UM extensions is the ability to combine together event-business logic. Given that any real-life application (like ZoomFlex) has quite a few commands, having a separate Command class for each command can become quite overwhelming. The ability to aggregate command logic into context-specific command classes is very useful.

I recently wrote a sample Flex application -- a simple Flex RSS Reader -- using Cairngorm.

I find that learning Cairngorm is made easier by looking at simple applications like this one. And the one I wrote earlier -- a simple contact manager.

When one looks at how Cairngorm is implemented across multiple applications, one starts seeing common patterns. And that is exactly the point of a framework like Cairngorm. Learning the framework is made easier by the fact that there is a certain repeatability and consistency in the way a Cairngorm application is structured.

I've just setup a Google Code project for the sample contact manager application I had written a while back. The contact manager used Flex, Cairngorm framework and ColdFusion backend.

The original version of the application was based on Cairngorm .99. I've been working on upgrading the application to Cairngorm 2.2.

Today I was building an application using Cairngorm 2.2. All was going well and I was very happy with the progress I was making. But then, I started facing this error while compiling the application.

From the text of the error it appears that the locale-specific bundle for CairngormMessages is not available/visible.

I finally got around to blogging a simple Cairngorm application that I had written a few months back just after completing my Flex Trainers' training.

The application is a simple contact manager that allows for contacts to be listed, added, edited and searched. The backend uses ColdFusion to store information in memory. For the sake of simplicity of this application, I have deliberately not used a database and used session variables instead.

I wrote this app to get my head around key Cairngorm concepts. I found this really helped to understand the basics of the framework. This application uses Cairngorm 2.0.
