Under catalog - manage categories section url key of category is not updating. Changing it and saving results in message that category has been saved successfully, but nothing changes.
There's a change in a catalog_category_entity_varchar however, but it doesn't affect anything.
Creating a new category and trying change its url key is working just fine, however.
Here are some questions - how to fix that? Or, if less specifically, how should it work and what controller(or observer) maintains url_key rewriting functionality?
UPD. Some data is inserted in catalog_category_entity_varchar table under certain value_id. But some stays the same. It somewhat seems that changes written and read from different places. Updating the not changing value_id seems to change url_key and even rewrites url_paths after saving it in the admin page. But I doubt that it should work that way.
