validating nested lists in validation.xml - struts

[Krikor Krumlian]

Hello All
I'm using validation.xml to validate some properties in beans so to do a simple validate we do :

<form name="someForm">
<field property="knumber" depends="required">
<arg0 key="someForm.knumber.label"/>
</field>
</form>

that's straight forward , Now if we have a list as one of the properties then
we do this

<field property="nestedprop" indexedListProperty="programs" depends="required">
<arg0 key="someForm.knumber.label"/>
</field>

Now that works too , The question what if we have a nested list in the above list what do we do ? Any ideas ? thank you
