Instead of using 2 onActivate() methods, you may also make use of
EventContext. It's often less verbose and better to read:

--
Object onActivate(EventContext eventContext) {
  switch (eventContext.getCount()) {
  case 0:
return NoContextPage.class;
  case 1:
this.myparameterstring = eventContext.get(String.class, 1);
  break;
  }
}
--

Hi,

You can have multiple event handler for the same event:

  http://tapestry.apache.org/tapestry5/guide/event.html

The one with the same no. of arguments as the no. of context
parameters will get called, as well as the no-arg one. I figured that
out with my own experiment.

Hope that helps.

Kenneth

2009-12-26 Thread Alfonso Quiroga 
What do you mean with overloadable? something like...

a) void onActivate()
b) void onActivate(String param)

you mean that? I think the easier way is to do only one method:

onActivate(EventContext context), tapestry5 will hit it always.
