The graphValidator is working well for me when I need to validate composite data such as address, credit card info, etc. The related fields have to be present in the same bean, and the bean is validated during the JSF processUpdates phase.
Is there any way that I can trigger the validation on an ajax event such as the 'onblur' event of one of the controls placed inside the graphValidator tags. For example when a zip code UI component is exited, and the zip code along with street address and city components are all placed inside the graphValidator tags.
Have you tried adding a4j:support for these inputs to initiate AJAX request?
