Hello, I'm wondering how Struts users handle the problem of separating business validation from page validation. By page validation, I mean things that can be accomplished with the Struts Validator, such as checking field lengths. And by business validation, I mean things that the business layer should decide, like whether certain combinations of fields are allowed, depending on various conditions.
The problem I have is that, in order to return the business errors back to the page, some knowledge of the page layer is necessary. For example, if a business error refers to a certain form field, you may want to highlight that field on the page. To do so, you'll need to know the name of the field (e.g. to add it to ActionErrors). But if the two layers are supposed to be separate, how do you communicate this information from the business layer to the page layer? Am I making any sense?
