Summary: Validating Arrays of simple Objects (was: [validator]
Validating Arrays of simple Objects)
Fix Version/s: Validator2
> Validating Arrays of simple Objects
> -----------------------------------
>
> Key: VALIDATOR-170
> URL: http://issues.apache.org/jira/browse/VALIDATOR-170
> Project: Commons Validator
> Issue Type: Improvement
> Components: Framework
> Affects Versions: 1.3.0 Release
> Environment: Operating System: Windows 2000
> Platform: PC
> Reporter: William Ferguson
> Priority: Minor
> Fix For: Validator2
>
>
> 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.
