The line is this:

object createdDate extends DateField(this)

and I haven't DateField imported so I get the option to import "net.liftweb.mongodb.record.field.DateField" in the quick fix context menu.

I think this probably isn't enough to recreate the issue though since it most often works. But maybe the stack trace can give some indication what's wrong?

Thanks,
Viktor

Status changed from Accepted to Fixed

I couldn't reproduce it, but you were right that the stack trace indicated a problem.. the fix will be in the next nightly build. If the error still happens, please reopen.
