We're looking for a few good people to participate in a study on AIR and the Flex SDK. If you are comfortable with ActionScript 3.0 and Flex, but have yet to build an AIR application, you may be eligible to participate. Even if you have already built an AIR application, you may still qualify if you've never built an AIR application that is tied to a database.

The study, which includes observations and conversations, should take about an hour of your time, and will be conducted online, so you can participate from anywhere with an adequate internet connection. Here's the kicker: those who are chosen to participate will receive a $100 Amazon gift certificate. For more information, check out the details on the Adobe Flash Platform Runtime Documentation blog.

Yesterday I heard about the new Blueprint Eclipse plug-in from the announcement on the Flex Doc Team's blog. I was intrigued by the convenience it promises, so I installed it and gave it a spin. The idea of having code samples just a click or key-press away got me pretty excited, because for me at least, seeing actual code is a critical step for me in learning how to use a particular class or interface.

Installation was pretty straightforward. It's been a while since I've installed an Eclipse plug-in, so I followed the Blueprint installation instructions pretty carefully.

You may have heard of the new Text Layout Framework, an ActionScript 3.0 component library that is based on the flash.text.engine package available in Flash Player 10. It first appeared on Adobe Labs last November.

At that time, we posted an overview of the framework that described the library as it existed last fall. Well the engineers have been hard at work improving the framework and have made quite a few changes to it. In fact, there have been enough changes that a new overview would be in order. As it turns out, I've been working on updating the overview, and have a draft of it ready for review. As it is a draft, I'm giving it an expiration date a week out from now, and will replace it with a new draft at that point if there are enough comments and suggestions to warrant a new version.

I'm back. I won't bore you with my personal travails, but will instead skip right to what I've been working on lately. Most recently, I've been documenting the new Text Layout Framework, which provides an easy way to take advantage of the immense power of the flash.text.engine package available in Flash Player 10.

Going forward, I'll be splitting my time between the Text Layout Framework and the creation of an updated version of the ActionScript 3.0 Language Specification.

Colin Moock blogged today about an interesting little ActionScript 3.0 string concatentation gotcha. I'll try to summarize what he said, but I encourage you to read his post and come back for my explanation.

The issue is that the following code:

generates the following error message:

Colin calls the error message misleading, and I can see why it seems so, but I'm going to argue that the message is accurate, even if it is obscure.
