Just make the output match the input:
Here's your output:
@OnEvent(EventConstants.PASSIVATE)
Object[] passivate() {
return new Object[] { team, team.getId(), this };
}
and your input should be:
void onActivate(Object team, Long teamId, Object someInstance)
{
...
}
But, you don't need all this, because you don't understand something...
I have seen this months ago tryign to create CRUD pages.

You don't need it, just don't use @At here.
Use tapestry defaults (at least just for now until you get all your
application working and you will want to make your urls prettier with @At).

The above routing scheme gets me what I want...

Most of this URL is useless.
Look at this:
org.tynamo.examples.pphl.pages.RosterQuery$00401b6140d
this is a encoding result of calling this.toString() -- which as decoded
becomes:
org.tynamo.examples.pphl.pages.RosterQuery@1b6140d
Why do you need this in URL? You can't use this anyhow in java anyway.
What do you think tapestry should do with this?
The other two parameters are 2 and 2. Not sure how you get 2 from
the "team" instance, I believe this is the work of encoders.
And you will always have these two numbers the same here.
Why don't you just remove one from activation context?
So what we have at the end is:
@OnEvent(EventConstants.PASSIVATE)
Long passivate() {
return team.getId();
}
and your input should be:
void onActivate(Long teamId)
{
this.team = findTeamById(teamId);
// you're already in context of "this" instance, so you don't need to
pass "this" in onPassivate.
}
and that url gets me to stay on the same RosterQuery page that I intended

Again, what do you expect if you don't play the rules?
You can declare your onActivate like this:
void onActivate(EventContext context)
{
// and context will never be null in this case -- why didn't you use
this?
