Build Identifier: 2.2.0

If an AggregateObjectMapping is part of the ReportQueryResult then ReportItem.resultIndex may be wrong. See Steps to Reproduce ...


Fix:
ExpressionQueryMechanism.java
replace: line 593
++itemOffset; //only a single attribute can be selected
by:

if (item.getMapping() instanceof AggregateObjectMapping) {
                        itemOffset += item.getMapping().getFields().size(); // Aggregate object may consist out of 1..n fields
                    } else {
                        ++itemOffset; //only a single attribute can be selected
                    }

Reproducible: Always

Steps to Reproduce:
Example:  

1. create @Embeddable class Money { String currency; BigDecimal value; }
2. create @Entity Item {Long id; Money money; String itemNumber; }
3. execute Query: select new QueryObject(i.id, i.money, i.itemNumber) from Items i

Error:
ReportItem.resultIndex = 2 for ResultItem i.itemNumber, should be 4 as Money has 2 fields
