Re: Validators of field
All fields in tapestry have a FieldValidator property @Parameter(defaultPrefix = BindingConstants.VALIDATE) private FieldValidatorObject validate; This will either be an instance of FieldValidatorImpl for a single validator or CompositeFieldValidator if there is more than one validator on a field. There is no public API to get the list of validators for a field and it will get messy if you try to inspect the FieldValidator using reflection. I would approach this by overriding or decorating the FieldValidatorSource service to store the information you want in the environment. Take a look at FieldValidatorSourceImpl for inspiration http://tapestry.apache.org/5.3/apidocs/src-html/org/apache/tapestry5/internal/services/FieldValidatorSourceImpl.html http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/services/Environment.html

So you can file a JIRA asking for the validators to add a CSS class automatically to both the field and label. Or, better yet, some new per-thread service that stores the validations applied to the fields. -- Thiago H. de Paula Figueiredo Independent Java, Apache Tapestry 5 and Hibernate consultant, developer, and instructor Owner, Ars Machina Tecnologia da Informação Ltda. http://www.arsmachina.com.br - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
