Minor Description
The Validator needs the ability to validate an array of simple Objects such as
Strings. Ie it should be possible to define a bean like:
class foo {
public String getBar();
public void setBar(String[] values);
}
and have the values of Bar validated.
Currently (validator 1.1.3 as ships with Struts 1.2.8, and looks same in 1.1.4),
to validate an array of properties you need to specify
property='somePropertyName'
indexedListProperty='propertyAtWhichCollectionIsFound'
This will iterate through the collection found at
'propertyAtWhichCollectionisFound',
and will validate the 'somePropertyName' property on each element.
But if it is a collection of Strings then there is no valid property name to define.
Ie you don't seem to be able to validate a collection of Strings.
To fix it, either 'property' needs to be optional (not recommended), or a new
approach to indexed properties needs to be taken. Perhaps by allowing 'property'
to define where the array of values can be found as well as any property to
validate on the elements (using dot notation), and having the Validator
introspect the values at each step and determine whether ot needs to iterate
over a collection. This would also solve some of the enhancements requests
that have been made for the Validator.
