Validation BEFORE submit
Hi
Our project requires multiple stages of validation of data editable in a
form.
At first there is a draft stage - all submitted fields should be validated
but not all required fields have to be filled in - all submitted fields must
be persisted to database.
Second stage requires more in depth validation and even more so during third
stage. The required validation stage change does not coincide with form
submission but is process driven - the user is required to subsequently
update/adjust form data to comply to finer grain validations.
It seems not a problem to dynamically change validators and validation code
based on state.
What I would like to do is to after state changes from say stage 2 to 3 and
more validation errors would occur on submission of form is to start the
editing of data in a form with these validation errors/messages already
showing - in other words I want to call the validation framework of the
page/form before doing the submit but already on the initial rendering of
the page+form and have the validationdelegate do rendering of error messages
and fields in error.
Is this possible?

I have written an integration between tapestry and fvalidate - amazingly
called tapestryfvalidate. You can download the jar file at:
https://tapestryfvalidate.dev.java.net/servlets/ProjectDocumentList
It's not documented though...
There is documentation on fvalidate at:
http://www.phil-taylor.com/fvalidate/
fvalidate is a really good javascript validation library, providing
loads of flexible validators.

It looks like something many tapestry developpers could use... Is there
a
possibility of seeing the code/putting in the wiki ?
Thanks in advance

We did something similar by wrapping @Form with a component that can
provided multiple levels of validation. For instance, the page can
easily provide it's own validation that is not easily doable with normal
validators (eg making sure 2 password fields are equal). This has worked
well for us as a flexible way of creating custom validation without
having to create validators (since most of the custom validation is only
used in one page/component anyway).
