[FLEX-23677] TileList Renderers Remain in Memory

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: Adobe Flex SDK 3.5 (Release)
• Component/s: mx: TileList
• Environment: Affected OS(s): All OS Platforms; Browser: Firefox 3.x; Language Found: English

Description

Steps to reproduce:
1. Create a view with a TileList control
2. Use a custom renderer
3. Populate the control with data
4. Remove the control from the view / stage (while profiling)

Actual Results: item renderers used by the TileList remain in memory

Expected Results: any/all item renderer instances should be collected

Workaround (if any): pull TileBase.as from the 3.5 SDK into your project and change measuringObjects to public. Before removing the TileList control from a view clear selectedIndex, itemRenderer, set tileList.measuringObjects = new Dictionary(true), clear the data provider, and schedule the control to be removed in the next frame via callLater.
