RE: hasErrors question

Never mind, I'm an idiot.  I put the SaveUserCommand.groovy file in the wrong project.  Doh!

Thanks anyways.

Hi,  folks.  I ended up using the Command object because the field was not a field in my class (ie confirmation password).

The documentation says that command objects can be in the controllers directory, so I put mine there.  However, the compiler tells me it can't find the object.  Is there something I'm doing wrong?

Code:
def save = { SaveUserCommand cmd ->
        if(cmd.hasErrors()){
                redirect(action:'create')
        }


Error:
[groovyc] Compiling 2 source files to C:\Documents and Settings\hbsuser\.grails\1.0.2\projects\simpleSecurity\classes
Compilation error: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, C:\code\simpleSecurity\grails-app\controllers\JsecUserController.groovy: 112: unable to resolve class SaveCommand

 @ line 113, column 9.
        if(cmd.hasErrors()){

Thanks!

That's exactly what I was looking for.  The Command object looks promising, too - that's the first time I've heard of it, but it looks designed for exactly what I'm doing.

Thanks!

See the "reject()" and "rejectValue()" methods in the Errors interface:

  http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/validation/Errors.html

"rejectValue()" is probably the one you want.

Cheers,
