It's really quite simple. What happens during a regular form
submission is that the browser includes a parameter based on the
button that was clicked. So if you have a button that looks like this
in HTML:
<input name="btnI" type="submit" value="I'm Feeling Lucky"/>
then when you click on it the browser will add the following to the
set of parameters posted:
btnI=I'm Feeling Lucky
Since Stripes knows ahead of time the set of events it can expect
(based on method names and @HandlesEvent annotations) it pokes into
the request and looks for any request parameters with a name that
matches one of the event names it knows about. When it finds one it
considers it a match and runs that event.
So to simulate it using a link you just add a parameter with the name
== eventName - the value doesn't matter. However, you shouldn't have
to concern yourself with this as you can just do:
<stripes:link beanclass="foo.bar" event="myEvent"/>

I think a literal explanation on how stripes is able to determine
which button has generated the event will come in handy. this is
because a lot of the times, i get into the situation where the
action i am expecting will have to come from a link, not a button on
a form. But i don't know how to make a link behave like a form post
with the action name in the right place
for stripes to pick up. I have had to resort to passing in a
parameter and letting the default handler handle the event and using
the parameter to tell which method to call.

Hi Cosmin,
A safer, more explicit, less 'hacky' way to do it is to use a hidden
input whose name is '_eventName' and value is the name of your event,
as in
<s:hidden name="_eventName" value="execute"/>
This would call public Resolution execute() on your action bean.
Cheers,
Freddy
