I'm currently developping the blog system for Ametys, and the comments are stored as metadata for the content type "Post", as a repeater.

And the repeater currently presents a bug: when there is one instance in the form, there is no way to remove it, the button doesn't work and there seem to be no JS errors causing this (according to Firebug) . I removed the mandatory fields just in case, it didn't help.

Even if "initial-size" is set to "0", I still wind up with one empty comment I can't remove.
