Description Doc CLA 2010-10-02 17:38:30 EDT 
JPQL Query : SELECT f1, f2, (f1.intValue + f2.intValue) AS computedColumn FROM MyClass f1, MyClass f2 WHERE f1.joinColumn = f2.joinColumn ORDER BY computedColumn DESC

This query throw a ClassCastException when trying to cast PlusNode of the SelectExpression to AliaseableNode. (Node return true on isAliasable but PlusNode doesn't implement the AliaseableNode interface)

PlusNode should be aliaseable...? (it's the only way to reuse it in an ORDER BY expression)
