[FLEX-23888] Scrolling list with custom item renderer causes incorrect rendering

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: Adobe Flex SDK 3.5 (Release)
• Component/s: mx: List
• Environment: Affected OS(s): Mac; Affected OS(s): Mac OS 10.6; Language Found: English

Description

Steps to reproduce:
1. Create a List or DataGrid component (seems to be anything that extends ListBase)
2. Create a custom component to act as item renderer
3. Assign renderer to the list using the itemRenderer property
4. Enter enough data into list to require scrolling
5. Scroll list

Actual Results:
Contents of list will jumble and sometimes duplicate. (Same with Flex 4 SDK)

Expected Results:
Items in list should maintain their correct order and values

Workaround (if any):
override updateDisplayList and reassign all values within the custom item renderer and then call super.updateDisplayList(). Values for the custom renderer appear to need to be stored on the renderer's data object, storing as class variables seems to have no effect.
