This post is as promised an example how you can make a button build on the OpenFlux - framework. This example was build for Flex 3. We are going to build that little simple button which is used in the MAC - dashboard, see image. It represents show and close more options just by [...]
I've been doing some maintenance and code cleanup on my ColdFusion ISP List, and noticed that some entries have not been updated in years. If you know of any companies that are no longer in business, or who no longer offer ColdFusion hosting, or anything else I should be aware of, please let me know. Thanks.
Since yesterday, I’ve playing with OpenFlux, and I must say once you get through the code/classes, you will and can easily build components for Flex. Now I’ve been extending Flex components since the beginning, ok since 1.5, and the way they have separated the views and controllers  in OpenFlux, I love it. Now the challenge [...]
The one and only Duane Nickullhas a new series called Duane’s World showing on his blog under the Adobe TV family. The first show is up now which includes an interview with Andre Charland from Nitobi and is an excellent review of rich application technology and web data transfer protocols (web services). It also includes a [...]
Excellent! I just found out that Computer Arts magazine have posted the article I wrote for them online as a PDF. So you can learn how to make a particle class from scratch and using it to create basic particle effects such as sparks and smoke. Here’s the [...]
The new launch of Adobe Feeds (MXNA) has gone well, but there are two issues I'm seeing people report: Maybe people have been getting "Header Length Too Large" errors. Interestingly, this comes from cookie-related code that CF7 tolerated, but CF8...
I now cannot load Skype on my Mac book Pro. I get logged in, I see the friends list, then bam, it dies. I’ve reinstalled different versions deleted preferences and plist files removed application I had installed (battlefield 2142) just prior to it not working, but that didn’t help logged in as a new user on MBP logged into [...]
As most of us Flex or Flash developers are quite aware that the code we generate is often error prone; error handling is an issue that mandates serious consideration. While talking about errors we need to deal with compile time errors which are primarily due to syntax incorrectness along with run time errors that are [...]

After writing about Eclipse/FDT3/Papervision3D and my heavy usage of templates to speed up my workflow, the natural thing to do was to create a Papervision3D template to use in conjunction with FDT3. You can grab the template from the Downloads page at any time (if I update it in the future, the newest version [...]
Bellow you can find a list tags and their attributes that are supported by flash player (and also by flex framework). This list applies to TextArea, TextFields and other controls that are html enabled. Anchor tag (<a>) Creates a hypertext link. href target Bold tag (<b>) Renders text as bold. Break tag (<br>) Creates a line break in the text field. Font tag (<font>) Specifies [...]
Artima recently posted two interviews with me which relate to Flex. First is an interview about Adobe’s Open Screen Project. The second is called Rich-Client Misconceptions. Also Bruce Eckel recently posted a very interesting article on Artima called “Concurrency with Python, Twisted, and Flex“. Let me know what you think about [...]

So far, I've looked at two possible replacements for Cairngorm's use of the Singleton pattern in its ModelLocator. I want to briefly introduce a third alternative before concluding this long string of posts.

Apologies for no meeting last month. Unfortunely neither speaker I had arranged culd turn up and it was too late (and we were too busy) to get something together at short notice. I have to thank the 2 presenters from March’s meeting, Matt Biddulph and Alias Cummins (I promise to get the videos of their [...]
Yesterday I wasted an hour or so debugging a Flex itemRenderer that I was using to display an image instead of a value in a DataGrid column. The renderer had to simply pick one of six images based on the column value, and so it contained a single <mx:Image> tag and a function that set the Image source dynamically. And then I called that function on the renderer's creationComplete event. Simple enough. Except that the wrong images were sometimes being displayed, the column had the right data, but the code used to select the image seemed to sometimes pick the wrong image. And what it picked seem to change each time I scrolled the DataGrid up and down! I actually ran into a very similar issue with a TileList renderer a few weeks ago, but then I had no time to figure out the cause, and so I hacked a workaround. But this time, having been bitten by the same issue twice, I had to find out what was going on. And what I discovered (by using traces and alerts) is that the creationComplete event does not get fired as I had expected. Rather, it seemed to fire only occasionally, and not once per DataGrid row, and so my image selection function was not being executed as expected. Once I had figured out the problem I searched the docs for any info on renderers and creationComplete, and found this page. And sure enough, "Flex might reuse an instance of the item renderer or item editor, a reused instance of an item renderer or item editor does not redispatch the creationComplete event". Well, that explained it. The right way to do what I wanted is to trap the dataChange event instead of creationComplete, as "Flex dispatches the dataChange event every time the data property changes". And so I am posting this for my own future reference, just to make sure I don't run into it a third time.
