Hi all,
even after scanning the doco, examples, source code and previous posts I
still can't get validation to happen for an indexed field in my Struts
(1.2.4) application working. I would really appreciate some help crafting
the appropriate validation definition.
My form is defined as
<form name="/cart/updateItems">
<field property="quantity" indexedListProperty="quantityArray"
depends="required, integer">
</field>
</form>
A 'quantityArray' parameter is supplied with the Request and is an array of
Integer like Strings.
The Struts ActionForm has the following methods:
public Integer getQuantity(int index);
/*
* NB it is not expected that this method will ever be called,
* but I think it is needed so that the commons-validator recognises
'quantity' as a property.
*/
public void setQuantity(int index, Integer quantity);
public Integer[] getQuantityArray();
public void setQuantityArray(Integer[] quantity);
But this combination causes the following Exception to be thrown during
validation:
24734 ERROR org.apache.commons.validator.util.ValidatorUtils - Unknown
property 'quantity'
java.lang.NoSuchMethodException: Unknown property 'quantity'

I tried dozens of different combos with no luck.
What do I need to do to validate a collection of properties of unknown size
using the commons-validator?
NB crossposting to both commons and struts lists.
