Issues with perform action line in 10.10

[cashxx]

I keep getting an error under OS X 10.10 with this line:
perform action "AXShowMenu" of toolbar 1 of menu bar item "View" of window 1

Error:
System Events got an error: Can't get group 2 of window 1 of application process "Safari". Invalid index.

Know why?

Which applescript are you referring to? I have a lot of them that use "AXShowMenu" here.
