-----------------------------------------
Hello,
Just wanted to say that I have worked on this issue and resolved some of the
problems that I mentioned. I also made form.js and core.js compatible with
dojo 1.1. I will post some patches soon.
Regards,
Numa

> Hello,
> After looking carefully at form.js and core.js. There are problems with the
> skeleton concerning form validation :
> - There is no way to override or intercept a form submit event if the form is
> submitted asynchronously, same for refresh or cancel ....
> this is very much needed if you want a function to be notified when one of
> this event happens
> WETHER by tapestry.form.onsubmit("myForm", myFunction) OR
> tapestry.connect("myForm", "onsubmit", myFunction)
> - There is no standard way to append a validation message to the stack of
> validation messages created from the form profile.
> One should be able to call tapestry.invalid_field('The field blah is
> invalid', isMissing ) And this should be appended to normal validation
> - Validation profiles are rather not clear, complicated and considered as
> instable in the dojo tree, all the validation should not depend only on this
> mechanism...
> - tapestry.connect assumes you connect a function in the tapestry namespace
> !? that's wrong, it should be :
> For 3 args : search for the function in the tapestry namespace and global
> namespace
> For 4 args : search for the function in the given namespace
> - validation using tapestry should not impose its method to show JS
> validation messages... Actually it is a a dialog widget from dojo. But it
> should be made simple to override that with your own presentation function :
> ex: tapestry.form.summarizeErrors(form, messages)
