Struts Form Validation
I'm letting the user of my form build up entry fields as they need them - ie :
<logic:iterate id="trade" name="requestForm" property="tradeColl"
indexId="ctr" >
<html-el:text property="tradeQuantity[${trade}]" />
</logic:iterate>
giving form fields .......
<input type=text name=tradeQuantity[0]>
<input type=text name=tradeQuantity[1]>
<input type=text name=tradeQuantity[2]>
etc ...
How can I use validation.xml to validate these fields when I don't know if a
field exists on a page ?
<field property="tradeQuantity[0]" depends="integer" page="3">
<arg0 key="request.tradequantity.displayname"/>
</field>
--- repeated for each field - but I don't know how many the user will
select --------
Maybe I should use the validate method inside the ActionForm and handle these
fields manually ?
Thanks for any help.

You can specify a "indexedListProperty" in the validation.xml
<field property="tradeQuantity" indexedListProperty="myCollection"
depends="integer" page="3">
<arg0 key="request.tradequantity.displayname"/>
</field>
