Hello!
Tapestry offers a couple of methods for validating form fields.
Version 4 is pretty great
and the new features are really helpful. Congratulations to the new
release!
My question now is focussing on validating complex objects. And I
think that I don't get
the big picture yet. Each of the complex objects propertys is bound
to form fields and each
of these fields has its own validation rules. Custom validators for
each field will do the
job just fine.
But there is one rule that must be applied for the whole object, when
each of the objects
properties has been set. At which point can I execute that rule? Is
there any "established"
best practice, some - in the spirit of Tapestry - fast and easy
solution?
I can - of course - use the listener method of the submitted form.
That would be a simple and
easy solution. But I would like to decouple the listener method from
validating these objects.
How would I accomplish that?
Thanks for any hint or recommendation!
Christian
P.S. I hope I was able to explain my "problem".
