Does your renderer use any event listeners? This is often a source of unsuspected references.

Hello, I am trying for days to figure out why the GC does not do it's work when my plain mx:DataGrid uses a custom item renderer in one of it's columns (plain mx:DataGridColumn object) that represents a plain mx:Image image. When the DataGrid is removed from the display list, Flex Profiler reports it is still lives in memory, along with all item renderer instances, the columns (all the datagrid classes are still alive) , and including the Image instances etc. IF I REMOVE the Image column from the DataGrid in source code and try again, everything is been garbage collected. So it clearly has to do with that column and in particular with the Image. Any ideas? I tried already tons of things, with no success, including doing image.source = null, or image.load(null) in an "remove" event handler in item renderer code etc. Please help!
