# Model methods that want to rollback transactions gracefully
# (i.e, returning the user back to the form from which the request was posted)
# should raise Instiki::ValidationError.
#
# E.g. if a model object does
# raise "Foo: '#{foo}' is not equal to Bar: '#{bar}'" if (foo != bar)
#
# then the operation is not committed; Rails returns the user to the page
# where s/he was entering foo and bar, and the error message will be displayed
# on the page
