to be).

> <html:option value="1">should work</html:option> 
> <html:option value="2">should work as well</html:option> 
> <html:option value="blah">this will fail validation</html:option> 
> </html:select>

> public class PropertyFilter implements Serializable

> Even if all values are integer, it will fail validation regardless. According to http://www.strutskickstart.com/IndexedPropertiesandValidation.ppt#18
I should 
> do something like: 
>     
> <field property="types" indexedListProperty="types" depends="integer"> 
> <arg0 key="text.validation.type"/> 
> </field> 
>     
> This time, it does indeed check all the values are of type integer, however, 
> if you do not select anything (the field is not required) the result is: 
>     
> java.lang.NullPointerException 
> org.apache.commons.validator.Field.getIndexedProperty(Field.java:796) 
> org.apache.commons.validator.Field.validate(Field.java:891) 
>   .. 
> Also having scoured all documentation in current and future builds and there is no example
of validating an integer array.
