Re: DynaValidatorForm and nested tags.

Thanks. I sure can see the difference.

can we use a DynaValidatorForm as an attribute in another DynaValidatorForm?
Thanks.

You don't have to use them, but they make things easier/cleaner when you
need to display fields that are updatable that are nested. For example here
are two ways.. one with JSTL and one with nested (I think you'd agree the
second syntax is easier to read).

<c:forEach items="${yourForm.listOf_A_Beans}" var="beanA"
varStatus="beanAlistStatus">
    <html:text 
property="listOf_A_Beans[${beanAlistStatus.index}].someProperty"
value="${beanA.someProperty}" /><br>
    <c:forEach items="${beanA.listOf_B_Beans}" var="beanB"
varStatus="beanBlistStatus">
       <html:text property="listOf_A_Beans[${beanAlistStatus.index
}].listOf_B_Beans[${beanBlistStatus.index}].name" value="${
beanB.someProperty}" /><br>
    </c:forEach>
</c:forEach>

<nested:iterate property="listOf_A_Beans">
    <nested:text property="someProperty" /><br>
    <nested:iterate property="listOf_B_Beans">
       <nested:text property="someProperty" /><br>
    </nested:iterate>
</nested:iterate>
