In your renderer, override set data(), set a "dirty" flag, and call invalidateProperties() then in an override to commitProperties, check the flag and perform your logic.
You cannot use creationComplete for item-dependent logic because renderers are recycled.

Item renderer basically consists of Image and Label component. Data provider is XML so Image and Label bindings are to da...@image and da...@desc which is displayed just fine. My question is, how can i check before item is rendered if da...@image is empty and if it is, set a custom image (like image_missing.jpg or smth) as Image component source? I mean, i know a logic to check that but not sure where to implement it? I tried in ItemRenderer when creationComplete event is fired but with no success so if someone could help me a bit with a simple example or smth i would really appreciate it.
