There are a variety of things you can do.
You can:
1) Put validation annotations on the bean properties that tapestry
will pick up
2) Put validation information in the property catalogs that
tapestry will pick up
3) Write and contribute your own constraint generator. For
example, in the tapestry5-cayenne integration module, there is a
CayenneConstraintGenerator that builds constraints based on metadata
available from the cayenne mapping.
For AppFuse, I would recommend #2 because it's non-intrusive (nothing
in the POJO) and it allows you to use the BeanEditForm, and it allows
you to easily modify (w/out compilation) the validation constraints.
Cheers,
Robert

Thanks for the pointer. I guess for something like AppFuse, using the
BeanEditForm (esp. with code generation) is probably not a good
idea. I'll
change things to generate the individual field elements so users can
more
easily modify the generated template.

I don't exactly get what you mean. You can validate for example
textfield
by passing a validator to
the validate parameter of some of the components. For example
<t:textfield
value="someProperty"
validate="required /> would make sure that someProperty actually
has a
value. See

Is it possible to do validation declaratively, or rather - only at
the
web
tier? AFAIK, I can only do validation with 1) annotations on the
model
object or 2) manually with if (blank) logic in my Page.
Thanks,
Matt
