Cannot remove all taxonomy terms from a post

[johnbillion]

Forgive the quick report but I'm filing this before I have to run out the door.

Situation: Standard list of term checkboxes for a custom taxonomy on the post editing screen. Once you've checked some boxes and saved the post it's impossible to then remove all the terms by unchecking all the checkboxes and saving the post. The previous selection of terms remains when the post gets saved. Off the top of my head I should think that the taxonomy doesn't get updated if the tax_input array for that taxonomy is empty.

Maybe I'm not doing something you are, but cannot reproduce on either trunk or 3.0.1

Are you using Quick Edit by any chance?

My first thought. But we fixed that too: [14117]

This seems to be a local issue. I'll test and update accordingly.

The site is using a custom meta box for the taxonomy and it turns out it didn't include the hidden tax_input[my_tax][] field. Adding the hidden field in fixes the problem.
