Velocity Binding Examples

[todds]

Hi,
I'm wondering if someone can provide me with some examples of how to do form binding and validation using velocity.

Thanks.

there's info on form binding in the ref docs at http://www.springframework.org/docs/...velocity-forms

Is there something specific you need?

Regards,

Yes, that's what I'm reading, but I'm getting this error, and I don't know how my classes should be set up.

at the moment your Controller is failing to be instantiated because you're trying to set a String property where a java.lang.Class is required as shown by the message;

Failed to convert
property value of type [java.lang.String] to required type [java.lang.Class]
for property 'commandClass'

Try setting the command class in your controller's constructor instead:

public LoginFormController() {
  setCommandClass(com.me.domain.Login.class);
}

alternatively, override formBackingObject() in your controller to provide a new or pre-populated command object for the form..
