After upgrading from grails1.0-RC1 to RC3 a problem occurred with dynamic scaffolding. To me it looks like the render-method has problems invoking a dynamic scaffolded view. In detail: For a given Domain class ----------------------------------------------------- class Shoe { String name static constraints = { name(blank:false) } } -------------------------------- Everythings works fine if I specify a controller for dynamic scaffolding in the standard way: -------------------------------- class ShoeController { def scaffold = Shoe } -------------------------------- If I try to create a record leaving the name field empty, the controller will display the create page again with the correct error message. When extending the controller by specifying an individual save-method like the following the problem occurs: ------------------------------------- class ShoeController { def scaffold = Shoe def save = { def shoe = new Shoe(params) // maybe some additional code here .... if(!shoe.hasErrors() && shoe.save()) { flash.message = "Shoe ${shoe.id} created" redirect(action:show,id:shoe.id) } else { render(view:'create',model:[shoe:shoe]) } } } --------------------------------------- In in case of an error (validation) there is no longer the create page displayed but a HTTP error 404 ------------------------------------------ HTTP ERROR: 404 /WEB-INF/grails-app/views/shoe/create.jsp RequestURI=/teststore/WEB-INF/grails-app/views/shoe/create.jsp ----------------------------------------- The save method I specified for demonstration is the original one generated by the generate-controller command. In the past (until RC1) the code above was working fine.
