Hi Thomas - Here's the problem code. The plain select works fine, but asking
for the count causes an error to be thrown if I use the non-hack method.
/**
* Get a List of the dogs that earned all of a list of titles in a given year
* @param titles array of titles to be searched.
* @param year four digit year to be searched
* @return a List of dogs that earned the titles
* @throws TorqueException if something goes wrong
*/
public static ListDog doFindDogsWithAllTitles( String[] titles, String
year ) throws TorqueException {
Criteria crit = getCriteriaDogsWithAllTitles( titles, year );
crit.addAscendingOrderByColumn( REG_NAME );
return doSelect( crit );
}
/**

year

throws TorqueException {
//TODO: Remove Hack once issue fixed

summary.addAggregate( count, new Count( DogPeer.DOG_ID ) );
ListListOrderedMapCI results = summary.summarize( crit );
return Integer.parseInt( results.get( 0 ).get( count ).toString() );
}
