Re: How to validate an entire object in a form (rather than a particular property of that object)
ok, thanks ... that worked. It threw up a different problem, but that'll be another post.

How to validate an entire object in a form (rather than a particular property of that object)
Another form-related question. I can see how to install a validator on a Form - Form#add(IFormValidator) - but it seems that AbstractFormValidator, the adapter, always requires a specific FormComponent to be specified in its error(...) method. How does one raise an error on the state of the form (and by implication, that of the underlying domain object) itself, without having to specify any form component? An example would be the classic fromDate endDate. A workaround would be to install the validator on - say - the endDate. But I'm after a general solution, rather than a solution for this particular example.

Hi Pedro, but my problem is that there is no form component to represent the form itself, is there? Any other thoughts?

you can override form.onvalidate() and do your validation there -igor On Mon, Apr 19, 2010 at 4:51 PM, Dan Haywood dkhayw...@gmail.com wrote: Hi Pedro, but my problem is that there is no form component to represent the form itself, is there?
