Can somebody tell me what this console message means and why it's
happening?
"Unable to create AX specifier for element:"
What are you using to exercise the accessibility - Accessibility
Inspector ?
It could be the UIElementRef your trying to use is for a UI Element
that has been
destroyed. Is the hierarchy changing while you navigate it?
If it's not that, then it most likely it means an asymmetry in the
parent-child hierarchy.
The problematic UI Element is being (unsuccessfully) looked for in
the children list
of its parent (whatever UI Element it reports as the value of its
parent attribute).
The failure to find it could be due to any number of reasons. E.g.
- the parent doesn't report the correct list of children
- the child isn't isEqual to its corresponding entry in parent list
(i.e. isEqual will need to be overridden if it's not pointer equal)

This is Cocoa accessibility code that I'm trying to get working.
The message
occurs when I have NSAccessibilityDebugLogLevel set to 3.
3? Why 3. I don't suggest using anything but 1.
-ME
It happens after
accessibilityHitTest and some navigation up & down the hierarchy with
accessibilityAttributeValue. Shortly thereafter I get an access
violation in
AppKit (next time through the event loop).
Hints? Ideas?
Thanks
