Hello !
Here's the use case i have to show when event attribute maybe requred.
>>Maybe it seems a bit weird but in my practice I often need to submit
>>"empty" form synchronously.
>>So i have invisible form without submit button and on user action (usually
>>click on link),
>>I need to submit that form to server with complete reload of page.
>>But unfortunately s:form tag doesn't not have attribute to assign event
>>without s:button/s:submit/s:image.
>>Sure, there're few workarounds, e.g. s:image with 1x1 px backgtound or
>>s:hidden with exact resolution name or _eventName, etc.
>>But i think it's more convenient to add event attribute to s:form, similar
>>to s:link.
Event attribute should be really optional. And be used for such weird cases,
when no submit button is available on form.
Or if you ain't gonna fix it anyway,such case should be described in docs to
supply best way of handling similar situations.
Thnx

> Now that Stripes supports a hidden field / request parameter called

> appropriate to use that mechanism for situations like:
> <s:form event="save">
> That will ensure that save is called, but still allows it to be overridden by
> buttons if that is desirable.
