The Tutorial has been updated for Torque-3.1!
If you find any problems with the Tutorial you can list them below.
The example at the bottom of the Peers Howto (On Criterion) should probably read like this:
<code>
Criteria crit = new Criteria();
Criteria.Criterion a1 = crit.getNewCriterion(ABC.A, new Integer(1), Criteria.LESS_THAN);
Criteria.Criterion b2 = crit.getNewCriterion(ABC.B, new Integer(2), Criteria.GREATER_THAN);
Criteria.Criterion a5 = crit.getNewCriterion(ABC.A, new Integer(5), Criteria.GREATER_THAN);
Criteria.Criterion b3 = crit.getNewCriterion(ABC.B, new Integer(3), Criteria.LESS_THAN);
crit.add(a1.and(b2).or(a5.and(b3)));
</code>
Note the conversion from int to Object in the Criterion. - JR (my first edit!)
