Validator Framework problem
Hi,
since I added a constraint for the length with minlength, I have the
following errror :
28-nov.-2006 21:31:33 org.apache.struts.validator.DynaValidatorForm validate

<validator name="minlength"

org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
depends="required"
msg="errors.minlength"/>
[...]
<form name="loginForm">
<field property="login" depends="required,minlength">
<arg key="required.login"/>
<arg name="minlength" key="${var:minlength}"
resource="false"/>
<var>

The method signature in your validation class (i.e. StrutsValidator)
doesn't match up with what you have defined in the "methodParams"
element for your minlength validator.

It will use the value in the "minlength" <var> element (which is "2"
in your case) as the second argument for your minlength message - what
it will display will depend on the message you've set up in the
resource bundle for the minlength message (key errors.minlength in
your case).
