Original Reporter: wdong18 Environment: Not Specified Version: 1.0.0.RC5 Migrated From: http://jira.grails.org/browse/GPMONGODB-220 Suppose Student domain is like: [classcode:01,studentcode:0101], [classcode:01,studentcode:0102], [classcode:02:studentcode:0201] and I want to get only classcodes like this: def c = Student.createCriteria(); def stList = c.list { projections{ property("classcode") } } and stList.size() is 2 instead of 3. The result is [10,20], not [10,10,20]
