Binding to Container children in Flex

Posted by Jacob Wright in ActionScript 3, FlexDec 29th, 2007 | 2 Comments I guess this week is my week for creating AS3/Flex hacks. I created an XML encoder/decoder that will accept a class-map and create your model from your XML and visa-versa. As part of that I have display objects as part of the model that needs saving out. I suppose you could liken it to MXML. In order for the XML encoder to work with DisplayObjectContainers I had to give it a way to work with an ArrayCollection to add or remove the children. So I subclassed LayoutContainer and gave it a property called "children" which is an ArrayCollection. Then I set up as a listener to it and every time something...

Automatic Casting Using XML

Posted by Jacob Wright in ActionScript 3, FlexDec 28th, 2007 | 1 Comment I am loving the E4X stuff in ActionScript 3. Once you get your mind wrapped around it and if you don't have to deal with namespaces it is very nice. Namespaces can be useful too, I just wish you could turn a namespace-agnostic-mode on and off. I just discovered a cool trick I thought I'd share with you. I found it when I was iterating through the properties of two objects to test if they were equal. The properties of one object were all Strings because it was parsed from a comma-delimited file. So, some Booleans or Numbers were strings of "true" or "10.5" while their counter-parts I was testing...

AIR Active Record

Posted by Jacob Wright in AIR, ActionScript 3, FlexDec 19th, 2007 | 17 Comments I've been working with AIR quite a bit since my side project is in AIR. I thought it would be pretty cool to create an active record implementation in AIR since I've got one on the server side. I have to use synchronous database connections for it so that everytime I access an object's related properties I don't have to use a callback, though it could be refactored to do that. Not my idea of fun though, and after an excellent presentation by Jason Williams, "Working with Persistent Data in AIR," where he showed how fast it was to retrieve data from an AIR database I figured it would be just fine. Currently...
