правило валидации очень простое - применяю к полю value2
и validation.xml выглядит так
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd">
<form-validation>
<global>
</global>
<formset>
<form name="calc">
<field property="value2" depends="required,validwhen">
<arg0 key="Zero divide1" resource="false" name="required"/>
<arg0 key="Zero divide2" resource="false" name="validwhen"/>
<var>
<var-name> test </var-name>
<var-value> ((operation != "div") or (*this* != 0)) </var-value>
</var>
</field>
</form>
</formset>
</form-validation>
проблема в том что валидатор выдает сообщение для required а не для validwhen. Не могу понять где ошибка
