Looks like I can get past that error and still use pagination:
with="&@categories" Don't know why hobo does not pick up the context.
The form works fine when I don't use ajax, but something goes wrong
when the controller is called with Ajax and part is used.
What does this error mean?
NoMethodError: You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.empty?
