360Flex E4X

Here are the materials for my session on introducing E4X at 360Flex 08 San Jose.  If you aren’t at 360Flex you are REALLY missing out, Tom and John really know how to put on a fun show.

360 Flex San Jose 08, E4X

Just got my confirmation to present at 360 Flex this August in San Jose. The sessions will focus on E4X, starting out fairly basic but hopefully moving very quickly to the more interesting advanced things that E4X lets you do in AS3. I normally run with a fairly fluid agenda so we can get conversations going during the session. So bring questions! We will be working through a ton of code samples as well.

Let me know if there are any specific areas of E4X that you find especially tricky (either to get working or even just remember) and I’ll see what I can do.

See you Tuesday Aug 19th @ 10am

In case you don’t know about the 360 Flex conferences it is an awesome conference designed to actually be affordable for developers. I’ve known the guys running the show for about 4 years now (before they were cool) and they really care about making the show something worth attending and it shows. So head on over and register now!

Fun with Canvas and DragDrop

So we were working on a simple little drag and drop interface for a project and ran into a weird bug that wouldn’t allow us to accept a drop onto a canvas no matter what we tried. Fortunately I remember running into the same problem with Flex 2 a couple years ago, unfortunately I couldn’t remember what I did to resolve it. I just don’t use drag/drop very often and didn’t remember the details.

So what is the issue? Here is the sample app:

Flex Builder Shortcuts

I’ve found that many developers don’t know some of the coolest time saving features available to them. This can be anything like patterns, frameworks, plugins, even databases. This post is focused on the one thing that most Flex developers use everyday, the IDE.   I know some of you out there are using Notepad (or more likely TextMate or VI), but this post is for the rest of us that choose to suffer through the slings and arrows of Flex Builder.

One of the great things about Flex Builder being built on the Eclipse Platform is getting most (unfortunately not all) the features Java (and other) developers have been used to for years.  This post focuses on the shortcuts I like to use nearly everyday.

ASyncToken and IResponder

So here is a weird little problem I ran into while using the generated webservice code in Flex 3. Basically if using the ASyncToken returned by the proxy class with an IResponder, the token never triggered any of the IResponder we never got a response. We tried to use the standard code like:


var service:MyWebService = new MyWebService();
var token:ASyncToken = service.myTestFunction();
token.addResponder(this);
