Re: [validator] conversion error while validating listbox component's value

i have implemented a workaround for this serverside required problem...
shortly: if validatorscript sets the required attribute, as you say, JSF
won't call my serverside validator when that field's value is empty... to
overcome this, i've commented the validatorscript's required attribute
setting code.. this means JSF can't see that field as required and not call
any required validator for that field... So, how can we call serverside
required validators? I've implemented an
idea<http://wiki.apache.org/myfaces/OptionalValidationFramework>from
myfaces wiki..

Implementation in short; i have developed an
RequiredValidatorChecker component.. it traverses all the component tree and
calls validate methods for found required validators...
i have entered a
blog<http://www.jroller.com/page/hasant?entry=jsf_bypassable_client_and_server>about
this solution...

So, you can think that serverside required validations are being called when
needed...

In fact, the problem is ConverterHelper can not handle array/list types in
current situation... although i can't think of any such scenario, somehow a
validation may be necessary to validate an array/list value.. so, how should
it work in this case? (May be such a scenario is not possible ;) )
