Top Stories by Rob Rusher

Another quick post… I was stuck recently with a Flex component that had a List with an itemRenderer. The itemRenderer contained another List with an itemRenderer. Now the problem with this is that the data had unique counts and the lists had variable row heights (variableRowHeight = true). The result was that containers would not dynamically resize enough to display the whole List. In other words, the List was clipped and vertical scroll bars were displayed. After trying several ways to get it to resize correctly and failing miserably, I extended the List component. As I was doing this, I found another post about an AutoSizingAdvancedDataGrid by the guys at WorkDay in which they had similar issues with the AdvancedDataGrid. Since the AdvancedDataGrid is similar to the List, I only had to make a couple of changes to get it working with the List component. Once I get... (more)

Security Soapbox – Decompile Flash/Flex

Having built/architected/developed/consulted many Adobe Flex applications and being one of the first certified Flex instructors in the world, I’ve seen a lot of Flex applications. Some good, some bad. But no matter how many applications or who I’m talking to, I always stress the importance of securing proprietary information. By securing, I mean don’t put it in your application. Unless your are encrypting your application and decrypting at runtime, you are subject to a decompiler exposing your secrets. There are Flash decompilers that will take any SWF and give you the source: Tr... (more)

Adobe Flash and Flex Accessibility with Screen Readers

First, yes, screen readers can read Flex applications. And yes, its fairly easy. But, I’ll discuss how in a future post. But, if you’d rather send people to your old HTML version of your site when using a read, there is good news. Flash Player has the ability to detect if a screen reader is running on the client machine, even if JavaScript is disabled and/or the Flex application is not compiled as an “accessible swf”. This is possible with the Accessibility class. It is important to note that if the Flex application is compiled as an “accessible swf”, the screen reader will also ... (more)

No One is Moving from Flex to HTML5

The fear, uncertainty and doubt (FUD) is been slung around by profiteers like folding chairs at a WWE event. The haters are still being haters. Nothing new there. But now I see JavaScript companies’ desperate pleas for Flex developers to start using their HTML5 software. The context is all wrong here.  Very, very few Flex developers have shifted, moved, changed over, or whatever you want to call it… to HTML5 (or anything else JS-based.) There is not a move to HTML5 I will go as far as to say that there is not a move to HTML5. The simple fact is that, developers are being develop... (more)

Back and Forth

For over a decade now, we have been trained to use the "back" and "forward" buttons in our Web browser to review or backtrack previously viewed content. We are trained to the point that there are even keyboard shortcuts. Unfortunately, this can be a problem when browsing Flex applications. Being the well-trained users that we are, we often forget that we could cause the Flex application to reload unwittingly. Fortunately, there is a solution that is built into the Flex SDK and HTML templates that are generated in a Flex Builder project. By default, Flex enables history managemen... (more)
