I have a couple of controls that are validated via a remote option. The 'success' function calls validator.prepareElement(element), which clears the error list.

I've tracked this bug down by changing a line in jquery.validate.js:918 (the start of the 'remote' function). When I return 'true' there, all the local errors show up. When I let the remote function do its job, the error list gets erased, and then the form is declared 'valid'.
