validation

[Mike Dewhirst <De...@UCLES.org.uk>]

What about adding some functionality to the ActionForm.validate() method,
which would validate formatting, i.e. if a form contains a Data JavaBean
with int's, Date's, etc. ActionForm.validate() would try to populate those
(like it does at the moment), but if it failed, it would automatically (set
with a true/false parameter) add an error to the ActionForm.errors object...

What do you people think?

Seems a lot of people are running into this limitation (not being able to
distinguish between formatting errors or invalid input or valid input),
resolving which would take struts a level up...

I would like to maybe even try adding this functionality in myself, but I'm
not sure how I'd go about that under the open source conditions..

Thanks,

Mike
