[jboss-user] [JBoss Seam] - Re: count(*) and group by

JPA QL allows a COUNT expression in a query, even though it's not legal (or portable) to write COUNT(*). See BNF grammar above taken from the JPA spec. So you could easily provide a custom JPA QL count query. The reason why in Seam the count query gets generated obviously has to do with the fact that the Seam framework supports the XML-based declaration of EntityQuery objects and query restriction fragments, without the developer being required to write any Java code.
