I have a form where the user will peform a simple calculation in order to
prevent spam (1 + 10 = 11). As a result, I would like to use the 'validwhen'
validation step to handle this. I am overlooking something I believe.
I have created the following:
1) Field Definition In validation.xml
<field
property="answer"
depends="validwhen">
<msg name="validwhen" key="errors.easy.math"/>
<arg position = "0" key="display.answer"/>
<var>
<var-name>test</var-name>
<var-value>(*this* = (firstArgument + secondArgument))</var-value>
</var>
</field>
2) Configure 'validwhen' validator in validation-rules.xml
<validator name="validwhen"
classname="org.apache.struts.validator.validwhen.ValidWhen"
method="validateValidWhen"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
msg="errors.required">
</validator>
3) Setup DynaValidatorActionForm
<form-bean name="contactInfoForm"
type="org.apache.struts.validator.DynaValidatorActionForm">
..
..
..
<form-property name="firstArgument" type="java.lang.String"/>
<form-property name="secondArgument" type="java.lang.String"/>
<form-property name="answer" type="java.lang.String"/>
..
..
..
</form>
I am not sure why this is not working. The DynaValidatorActionForm is setup
with all fields as strings - this is a bean so this is fine. I know that the
'validwhen' validator is setup properly because I am using it to validate two
email addresses. Since I am relatively new to Struts, is there a problem since
the types are not Integers? Where is this conversion taking place? I am
having a hard time with this. Please advise.
Thanks,
J.W.
