Naming of templates and controllers with AJAX

[rothen]

I just stumbled across an ugly little technicality of grails: Don't give a template in the layout directory the same name as a controller, especially if you work with AJAX calls that render only a part of a page. It seems that every action in a controller loads a template with the same name if it finds one. With an AJAX request this just doubles your template elements. It seems that this feature is intentional, it is called layout-by-convention.

It is intentional.  In section 6.2.4 of The User Guide
(http://grails.org/doc/latest/) under the "Layout by Convention"
heading...

"You can create a layout called grails-app/views/layouts/customer.gsp
which will be applied to all views that the BookController delegates
to."
