Hi, I am using coarse grained action forms that are re-used by various action classes. Each of these action classes serve a different page and retrieves information from the backend so that the jsp page can show it. Now because I am using coarse grained forms, I have now way of knowing which fields to validate because the same form serve multiple actions. Also, if I use the ActionForm class to validate the client data, the ActionForm has to be responsible for re-initializing that page with backend information if validation fails. Therefore, even if I change to very fine-grained DynaForms and use the validation framework so that each action maps to one form, I will probably have to figure some way of fetching backend information if validation fails.
Currently, I am doing all the client input validation in the action classes because it seems to be the most simple solution; however, it has the caveat that the action class is now responsible for both validation and backend service delegation. I am just wondering if there is a more elegant solution using the action forms as the validator. Any help is greatly appreciated.
