Subject Re: fetch group question
Date Mon, 15 Oct 2007 02:43:47 GMT
Sorry,

The code should read as:
Query query = pm.newQuery(Person.class);
FetchGroup criteria = new FetchGroup(Person.class);
// or I could also do
// FetchGroup criteria = new FetchGroup(query);

criteria.add("firstName").add("lastName");
query.getFetchPlan().clearGroups().addGroup(criteria);
