Peter Wharmby commented on FLEX-33600:
--------------------------------------
Hi
Yes, it looks very likely that this is the fix required.
The check for a null accessibilityProperties is there in two of the places.
In our code it is there in all four references just in case but I forget
which was the one that was causing the problem
I will try out the bulid to check if this works for us in practice but
it will be a couple of days to get hold of an offending PC (doesn't
happen with all of them).
Cheers
Peter
