As I discussed previously, caching can have it’s advantages. It makes referencing objects and binding much more straight forward. Unfortunately, it comes at a performance cost. Since I’ve been using caching, there are some important things to keep in mind when you use caching to make sure your data sticks around and your performance doesn’t [...]
Some thoughts on caching objects in Flex
Category: Flex, PerformanceThe project I’ve been working on for a while now uses caching. This means that the application will store the objects returned from the server in a DataCache and anytime objects are returned from the server, they are synced with the DataCache.
ArrayCollection contains() uses your sort!
Category: Flex4Here’s another gotcha that took me a while to realize what was wrong. I was using an ArrayCollection to hold a collection of items. I had a custom sort applied since the items were typed objects that needed to be sorted according to certain, out-of-the-ordinary fields. In the sort method, I was comparing values and [...]
Don’t forget the down state

Runaway ArrayCollections

It took me a while to find the reason, so to help someone else with the same problem, I decided to write about it. Background I had an ArrayCollection of custom classes called Build. Those Build [...]

Chat widget
Category: RandomThe little “Chat with Marty” module on the left side of my website is a cool little widget I got from Google.

The thought process [...]
