Lists, ItemRenderers, and Styles….oh, and Garbage Collections
So, as I continue my trek in Flex Builder Profiler land I discovered a interesting one. Say you have a List used in some component and this List uses a custom itemRenderer and this fancy custom itemRenderer you cooked up uses a inline Style. You crank your application up and with that silly attempt at a sly smile, pat yourself on your back. Then you click that button you have in your app that removes a instance of this component from the display list, yeah, you are working on a pod-like system here, eh? Thinking nothing of it you continue along the trail of happy codeness, that is until you start profiling that app in your most favorite FB Profiler tool. WTF? Your List is never GC’d? I can add 10 of these in the UI as a result of mashing this fancy ‘add new pod’ button and even though that fancy ‘delete me now’ icon, which calls removeChild(), is mashed 10 times, the 10 pods are still hanging out in memory? Yup, shocked me too, actually a good shock as I was falling asleep in front of these memory graphs…hehe.
Assuming my coffee is not laced with the usual ‘make me stupid’ sauce, I filed a bug. Check it out here https://bugs.adobe.com/jira/browse/SDK-15861
