Justin Mclean commented on FLEX-35312:
--------------------------------------

Patch looks fine but I don't see that ClearCache is being called by anything?

 A minor thing functions usually start with a lower case letter.

> The Spark GridViewLayout uses strong dictionaries for caching itemrenderers, often leading
to a situation where those itemrenderers are never released to the garbage collector.
> The proposed patched changes GridViewLayout to use weak reference dictionaries and additionally
adds a public method to Grid to allow the client to explicitly flush the item renderer cache.
