Description

Steps to reproduce:
1. load the attached swf
2. click the TestList button
3. flash goes into an infinite loop

Actual Results:
infinite loop / interface crashes

Expected Results:
no crash

Description:
According to the IList interface a length of -1 is valid (and needed) if the length is unknown. Spark DataGroup crashes in this case. I've attached a patch to fix this problem.

All this is with Flex SDK 4.1.0.14345
