I want a argument in my xml field-element, for the max and min lenght validation. i done it based on the dtd file bot it dont works. the validator doesnt get the value. an so ich have an nullpointer exception.
how must i write the argument in the field element?
<field property="name"
depends="required,minlength,maxlength">
<arg0 key="register.validate.name"/>
<arg1 name="minlength"
key="${var:minlength}"
resource="false"/>
<arg1 name="maxlength"
key="${var:maxlength}"
resource="false"/>
<var>
<var-name>minlength</var-name>
<var-value>1</var-value>
</var>
<var>
<var-name>maxlength</var-name>
<var-value>255</var-value>
</var>
</field>
Arg0 is the argument for all 3 rules - required, min & max len. Arg1 name="minlength" is used by minlength Arg1 name="maxlength" is used by maxlength
