Reduce the size of a Flex 3 application avoiding unnecessary references with the getQualifiedClassName() method

04/23/2008 06:54 pm by Marco Casario | RIAvolutionize the web in Flex

There are many ways you can use to control and optimize the performance of your Flex applications acting both on the server as well as on the client side. The first optimization you can implement is by reducing the time tha application takes to start. Externalizing assets and searching for linker dependencies are simple approaches that can save the end user a lot of time in loading te Flex application. It's common for developers that at the end of a Flex application they are inadvertently linking in some classes that they never use. I've found that another common error is to let the compiler to include classes that the application won't use for its entire life. That's a shame ! So an important step to check before compiling and deploying a Flex app is to check that you're not including unused classes

Host A Flex Camp

04/23/2008 04:45 pm by Ben Forta's Blog in Flex

I've been blogging Flex Camp announcements for a while, and have spoken at many too (the next one I plan on attending is May 15th in Toronto). Flex Camps are fun, informative, educational, and great networking tools, too. If you're interested in hosting your own Flex Camp, visit this Flex Camp page at flex.org and download the Host Your Own Flex Camp Guide. You'll find all the details you need, as well as information on how Adobe may be able to help fund your event. Oh, and then don't forget to invite me! ;-)

Sending extra data in Java Exceptions to Flex Clients

04/22/2008 03:05 pm by Adrian Aioanei in Flex

When building Java services there is always need for handling exceptions thrown by all kind of sources. Wether those are ConstraintViolationException thrown by wrong database queries, NullPointerException thrown by wrong data manipulations or any other exceptions, all of them should end up handled in the Flex application calling the services. One wrong usage of data transfer [...]

Exctract and learn from the Flex 3 data visualization source code (the charting controls, the AdvancedDataGrid classes, the OLAP classes, and the automation classes)

04/22/2008 02:54 pm by Marco Casario | RIAvolutionize the web in Flex

Each time I tell that Flex 3 is open source, during my Flex 3 courses and sessions, people don't believe it. So I copy the entire Flex 3 SDK libraries into a new Flex 3 project and show them the actionscript classes fo the SDK. Then I go ahead and tell that not only the standard Flex 3 SDK is open source, but also the charting controls, the AdvancedDataGrid classes and all the stuff that come with the Professional version of Flex Builder 3 are open source. In order to open the data visualization source code we must have these two requirements

Why you should consider Spring in your Flex, BlazeDS and Livecycle DS scenarios

04/22/2008 12:05 pm by Marco Casario | RIAvolutionize the web in Flex

Today during a presentation about the use of Flex in enterprise scenarios, while I was illustrating the benefits of using the factory mechanism of BlazeDS to integrate it with Spring, a developer asked me why use Spring for Flex development (I guess he does not come from the Java world). I think that the answer could be obvious to most of you but I want to share my thoughts with you about that topic.

Improving Cairngorm’s ModelLocator Part 3 - Hiding the singleton II

04/21/2008 05:34 pm by Big Room in Flex

In the previous post in this series, I showed how we can use a second class to access the ModelLocator singleton. This enables instances of this second class to be created, modified, bound to and disposed of as often as one wishes while maintaining the integrity of the data in the core singleton. Each instance of the second class mirrors the data in the singleton, modifying the data in an instance modifies the singleton, and modifications to the singleton are immediately reflected back out to every instance of the second class...

ColdFusion 8 and Flex 3… The best thing since sliced bread!

04/20/2008 10:40 pm by Dylan DePass in Flex

Over the last few months I’ve been learning ColdFusion and the more I learn the more I’m amazed at how powerful and easy it is to use. I used to use php for server side code but after reading so many articles on how Flex and ColdFusion works so well together I had to see [...]

04/16/2008 06:57 pm in Flex

This afternoon I stumbled across Kaushik Datta’s blog post ‘Toyota’s Model Selector in Flex‘ where he mentions a new Flex site for Toyota. So I thought I’d take a look. Initially it looks very nice, but after a short play with the sliders my Firefox browser crashed and displayed a weird error message. It was not [...]

ImageCropper may be configured to constrain the cropping to an aspect ratio. For example, defining a cropping rectangle with a width of 200 pixels and [...]

Flex 3 Skin Transitions with Degrafa and AnimateColor

04/15/2008 04:54 pm by James Ward - RIA Cowboy in Flex

It is always fun when you discover new product features that you never knew existed. This happened to me last week as I was looking into Flex 3 skinning. It turns out that not only can you use a single class with states to define component skin states (like “up”, “down”, and “over” [...]
