I agree that the candidateCollectionExpression description is a bit
cryptic.
Boy, it's been a long time since I thought about subqueries. Can we
also provide single-string versions of the examples? That would be
helpful.

Hi Craig,
the examples are very informative. I must say that I find the
description
for candidateCollectionExpression
"The candidateCollectionExpression is the expression using tokens from
this query that represent the candidates over which the subquery is
evaluated. "
a little bit cryptic (I actually find the paramater name more
descriptive
than the description). Especially "tokens from this query" (is
tokens a
common word for this and may be it should be stressed that this
query is the
outer query?) and "over which the subquery is evaluated", but may
be this is
needed for the spec.
Anyway, do I understand it correctly that it is the same as:
....
sub.setFilter(":departmentEmployees.contains(this)");
Query q = pm.newQuery(Employee.class);
q.setFilter("this.weeklyHours > averageWeeklyhours");
q.addSubquery(sub, "double averageWeeklyhours", null,
"this.department.employees");
kind regards,
Christiaan
