The hidden field generated by g:checkBox places the underscore at the beginning of the checkBox's name even if the name has periods (dots) in it, so that it's not included when binding a "sub-hash" of params to a domain object. For example, if the Book class has a paperback boolean, then a checkbox declared as:

<g:checkBox name="book.paperback" />

and bound in the controller with:

new Book(params['book'])

or:

book.properties = params['book']

will not set the paperback property to false if the checkbox is unchecked. This is because the hidden field generated by the g:checkBox tag has the name _book.paperback. Changing this (for example, by using straight HTML instead of the g:checkBox tag) to book._paperback seems to fix the problem, which suggests that the g:checkBox tag should prepend the _ to the last component of the dotted name, rather than to the name as a whole.
