Flex makes opening popup windows a very easy task, and generally speaking closing them is simple as long as you know what type of display element they are. However, let's assume you wanted to close all popups regardless of what they are. The only current example I could find on closing all popups in Flex assumed that every popup was of the same type (nonetheless, this post was extremely helpful to me in solving this problem).

I am building a proof-of-concept application using Flex and AIR. In this application I use the code for minimizing to the system tray whereby it asks if you want to close the application or minimize when you click on the close button. Unfortunately, if a modal popup was already open, the Alert would appear underneath it. What I wanted was simply to close any open windows and then open the Alert, and here's how I did it...(keep in mind I am still learning Flex so, you Flex gurus, feel free to suggest improvements)

This is a quick post on a simple problem in case anyone runs into this issue and can't determine the reason. I had existing AIR applications set up in my beta install of Flex 3. As recommended by the installer, I removed the beta before installing the final version of Flex 3 released yesterday. ObviouslyI open Flex 3 for the first time, my pre-existing projects are missing. To import them with the prior settings, you simply go to File > Import > Flex Project, choose the "Project Folder" option and browse to the project folder location.

The catch is that since I also updated my install of AIR to the final version I was finding that hitting "Run" had no result...nothing happened. Well, what I needed to do was open the AIR application's XML descriptor file and change the line that read:

<application xmlns="http://ns.adobe.com/air/application/1.0.M6">

...(for the last public AIR beta) to:

<application xmlns="http://ns.adobe.com/air/application/1.0">

...for the current 1.0 final release.

One new project and no less than eight updates this week. On another note, you heard it here first! Flex 3 and AIR were released today! Unfortunately, I cannot reveal the source of this highly sensitive leak, but never let it be said that this site doesn't keep you on the cutting edge.

My latest article has just been posted on Sitepoint. It covers my personal favorite new features in ColdFusion 8 (at least, those at the moment as this tends to change throughout the lifetime of a release). Most of my readers are probably familiar with these features, though if you haven't used ColdFusion 8 much yet, I do go into some brief examples of things like the Ajax integration and Multi-threading. Anyway, I am just grateful for the opportunity to evangelize a great product and a particularly excellent release.

ColdFusion 8: Believe The Hype

Five updates to existing projects this week. Generally speaking it was a quiet week. Maybe its the winter. I for one am already ready for this winter to be over. I think it has rained or snowed 90% of the time with the sun being only a distant memory at this point.
