This happens because the changesets feature type has not been registered as a public one in geoserver.
I've added better error reporting, not sure I can make it work without having that feature type registered thought.

Can we have the feature type automatically register in some way? Maybe when people enable versioning?

Not easily.
In a perfect world, I would have a configuration subsystem that would throw events when stuff gets added, this way I could register a listener so that when that datastore gets added the changesets type would get configured. I would also have a config system that would guarantee me the availability of certain basic styles.

With current config subsystem I have to make the data module directly depend on the versioning datastore to do so (and using the single listener that Justin added some weeks ago to flush the feature type schema cache)... moreover, I have no guarantee I can find a style that's compatible with changesets, for what I know the user may have only styles that do depend on certain attributes being available. So I would need to scan the styles looking for one that I can use, and inject on the fly one if I don't find it.

Ok. I guess we just need to be sure to add good documentation that says the featureType must be enabled.
