[FLEX-24788] Flex tree control (mx:tree) does not always see changes in selection

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: Adobe Flex SDK 4.0 (Release)
• Component/s: mx: Tree
• Environment: Affected OS(s): All OS Platforms; Affected OS(s): All OS Platforms; Browser: Firefox 3.x; Language Found: English

Description

Steps to reproduce:
1. Build the TreeExample code in mx:Tree
2. Select "Outbox"
3. Expand "Inbox"
4. Select "Marketing"

Actual Results:
"Marketing" is not selected and the "Selected Item" remains "Outbox"

Expected Results:
"Marketing" should be selected.

This works correctly in flex 3, but fails in flex 4.

Workaround (if any):
In flex 3, the openDuration parameter defaults to 250. In flex 4, it defaults to zero. The code to correct the indexing when a tree branch is opened is triggered when the tweening is complete. Because an openDuration of zero means there is no tweening, the re-indexing never occurs. To workaround the problem, set the openDuration to something non-zero. "1" works if you still want the impression of no tweening.
