The WebWork "bang" notation for calling methods doesn't support per-method validations.
However, the Struts-style wildcards do support per-method validations. Validations can be specified just as if the method name had been hardcoded in the configuration. The syntax is "ActionClass-actionName-validation.xml. In the case of a create method of a Course class that was invoked with the name Course!create.action, the validation configuration would be Course-Course!create-validation.xml. Note that it is the action name not the method name. (Though, I often wonder if the method name would make more sense.) The MailReader application for Struts 2 uses wildcards as well as per-method validation. HTH, Ted <http://www.husted.com/ted/blog/> On 4/5/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote:
Ted -- This is a great explanation! Can you add to this how Validator naming works with respect to wildcard methods? For instance: CourseAction list() create() Course-validation.xml and supposedly support for something like Course-create-validation.xml I think I remember reading something about this support at some point?
