#error-message

Here's a way to get data from UI compoments, assign them to a Grails domain class and save. If there's an error the first error message will be displayed by the notification block. $('#save').on('click', { def product = new Product( name: $('#name' ).val(), category: $('#category').val(), unit: $('#unit' ).val() ) if(product.save(flush: true)) { notify("New Product ${product.name}: ${product.id} Saved") $('#name, #category, #unit').val(null) $('#name').focus() } else { def e = product.errors.allErrors[0] def comp = $("#${e.field}") notify(message(error:e), comp) comp.focus() } })
