Spent quite a lot of time getting Flex automation working with the RandomWalk example - there where several obstacles to recording but now playback is failing.

This is with the latest version of the flex SDK (flex sdk 4.1 – build 16076)

it gives the following error:

AutomationManager:pushMouseSimulator() – In Air we are not allowed to do this on the Window object. We need to settle this with AIR team
Error #1009: Cannot access a property or method of a null object reference.: TypeError: Error #1009: Cannot access a property or method of a null object reference.

This occurs for QTP, FlexMonkey and RiaTest
The same code works for sdk 3.5
I am using the version of RandomWalk with the patch from this flex automation experts blog – so I am 99% certain its the inside the AutomationManager or perhaps there is another patch required for RandomWalk code
