Invalid SQL syntax for count() query with Entity which have Identity composite key

Reported by Cyrille37 | April 9th, 2011 @ 02:34 PM | in 1.2.2

Playframework 1.1.1

Summary

When counting Entity which have Identity composite key, the method count() throw an SQLGrammarException but the count("") works.

Detailled

@Entity
public class Order extends GenericModel {
 @Id
 public int clientId ;
 @Id
 public int productId ;
}

Then :
Order.count() throw an org.hibernate.exception.SQLGrammarException but
Order.count("") works fine.

Here is the JPA error :

  14:33:47,627 WARN  ~ SQL Error: -11, SQLState: 37000
  14:33:47,627 ERROR ~ Unexpected token: , in statement [
   /* select count(e) from models.Order e */
   select top ? count((order0_."clientId", order0_."productId")) as col_0_0_ from "Order" order0_
  ]

The generated SQL is false, because it put all identity keys as SQL count() operand parameters ; but the SQL count() operand accept only one Column.

Try similar query in mysql :

  select count( (clientId,productId) ) from Order ;

generate a error :

  Error Code: 1241
  Operand should contain 1 column(s)
