 How to correctly use alternate messages in the Struts validation framework.
  Based on the following information from Programming Jakarta Struts Chapter
11 The Validator Framework
http://books.google.com/books?id=E874l0jaUGQC&pg=PA260&lpg=PA260&dq=change+the+key+values+in+the+validation-rules.xml+if+you+plan+to+use+alternative+messages&source=bl&ots=t5zzY8fSs4&sig=wEOspEiq8XsU2su4yD1WlCz8H6w&hl=en&sa=X&ei=8_ZLT6TOHoPi0QGB4YiTDg&ved=0CCIQ6AEwAA#v=onepage&q=change%20the%20key%20values%20in%20the%20validation-rules.xml%20if%20you%20plan%20to%20use%20alternative%20messages&f=false






“You should add these to your application’s resource bundle, or change the
key values in the validation-rules.xml if you plan to use alternative
messages.”



I have the following code in validator-rules.xml file.



<validator   name="required"

            classname="StrutsValidators"

               method="validateRequired"

         methodParams="java.lang.Object,

                       org.apache.commons.validator.ValidatorAction,

                       org.apache.commons.validator.Field,

                       org.apache.struts.action.ActionMessages,

                       javax.servlet.http.HttpServletRequest"

*                  msg="errors.required.new"/>*



            <validator   name="mask"

            classname=" StrutsValidators"

               method="validateMask"

         methodParams="java.lang.Object,

                       org.apache.commons.validator.ValidatorAction,

                       org.apache.commons.validator.Field,

                       org.apache.struts.action.ActionMessages,

                       javax.servlet.http.HttpServletRequest"

              depends=""

*                  msg="errors.invalid.new"/>                  *





I added the following string to the properties file.



errors.required.new={0} is required NEW!!!

errors.invalid.new={0} is not valid NEW!!!.





My validation.xml file looks like this:



<field property="attribute(Number)"
depends="required,mask,maxbytelength,nonce">

*                                                <msg name="required"
key="errors.required" /> *

                                                <msg name="maxbytelength"
key="errors.maxlength" />

                                                <var>


<var-name>maxbytelength</var-name>


<var-value>32</var-value>

                                                </var>

                                                <var>


<var-name>form</var-name>


<var-value>Info</var-value>

                                                </var>

*                                                <msg name="mask"
bundle="mytest"key="errors.invalid" /> *

                                                <arg0 key="label.Number" />

                                                <var>


<var-name>mask</var-name>


<var-value>^[0-9\-() ]*$</var-value>

                                                </var>

                                    </field>



I still see the standard error messages such as the ones listed below
displayed on the UI.

errors.required.new={0} is required.

errors.invalid.new={0} is not valid.



Is this a Struts bug?  If not, what is the right way to use alternate
validation message in this case?



Thanks a lot.
