Understanding the Flex Component Lifecycle
UPDATE: I gave a talk on the Lifecycle of a Component in Flex 4 first at Bangalore Flex User Group and then at FlexMania conference, check out the video recording, slides and code.
Someone recently asked me how to go about understanding the Flex Component Lifecycle .. my usual answer to this is to go read the documentation, then the source of UIComponent and a few basic components like Label, Button etc. .. I also sometimes point people to the Building A Flex Component [PDF] presentation from Ely Greenfield which I’ve found useful in the past … this time though, I was also reminded of some recent presentations I had seen on the subject and found interesting .. so I thought I’ll share them here as well ..
Diving Deep With the Flex Component Lifecycle,
presented by Brad Umbaugh and RJ Owen at 360 | Flex, San Jose.
Creating New Components in Flex 3,
presented by Deapa Subramaniam at MAX 2008
Also, while we’re on the subject, if you’re in Bangalore you should consider attending this Friday’s Bangalore Flex User Group meeting where Chetan Sachdev will be presenting a talk on Custom Components and the Component Lifecycle.

Hey Mrinal,
Nice work!!
Its what I read somewhere that if an Object is set to null
and if some eventlisteners are added to it, its not garbage collected.

Hi Hissam,
EventListeners can hold weak and strong references to an object … checkout the useWeakReference parameter in the addEventListener method http://livedocs.adobe.com/flex/3/langref/index.html
If an event listener holds a strong reference (which is the default behavior) an object will not get garbage collected unless the listener is removed.
