[attr]_changed? always nil in "should_generate_new_friendly_id?" method

[anthony-robin]

I am using friendly_id and friendly_id-globalize gems in my Rails project.

Every time I update an article, the method title_changed? is always nil even if I change it in the form which make slug never being updated.
It might be a gem bug.

For more details, I opened a StackOverflow post.

Did you try attribute_changed?('title')?
