Ernest Monklitch commented on TAPESTRY-2109:
--------------------------------------------
The ability to submit the form WITHOUT validation is really important. For an
example I have a list of tu -objects and user can add as many as he/she likes.
I have all kinds of other data in the form, and the add tu button must send
all that other data to server while at the same time so that no data is lost
during the tu addition. Hence actionlink cannot be used.
And this must not initiate client side nor server side validation, user can add
as many tu:s as she/he likes before entering any other data. That other data is
not needed until save operation that happens when user SAVES the form.

> There is a need for more submit types...
> although <input type="submit"> and <input type="reset"> are trivial even
> without a component,
> there is a problem when a type="cancel" is needed.
> The issue here is that in case of cancel client validation must be skipped,
> and that is not possible with current
> Submit component.
> I don't know how submit type=cancel works for T4 so I've implemented it how
> it seemed right for me.
> extract from javadoc for the "type" parameter

> * Determines the button behavior, <b>"submit"</b> - a normal form
> button, <b>"reset"</b> - reset form (locally),
> * "cancel" - works like an actionlink, generates a "cancel" event
> instead of "selected" and the form is not submitted
> * (if javascript is disabled form will be submitted, and "cancel" event
> fired as well),
> * <b>"submitcancel"</b> - works like "cancel" but behaves consistently
> with and without javascript
> * submission (this is usually desirable).
>
> input type=cancel uses javascript to redirect to an action link url, thus
> avoiding form submission,
> so I've added type=submitcancel which still submits the form but avoids
> client validation.
> both generate "cancel" event which is different from the "selected" event
> on top of all that the type=forced could be easily added to call "selected"
> event while skipping client side validation
