ok, thanks ... that worked.  It threw up a different problem, but 
that'll be another post.

FeedbackMessages API, is expection an Component object as

will make sense:

formComponent.getForm().error(

An example would be the classic fromDate < endDate.  A

solution for this particular example.

How to validate an entire object in a form (rather than a particular property of that object)

2010-04-19 Thread Dan Haywood 

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.


Thanks
Dan
