[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-4743) Bug in BooleanLiteralNode with CustomType

Bug in BooleanLiteralNode with CustomType ----------------------------------------- Key: HHH-4743 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4743 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Reporter: Jean-Francois Larouche Assignee: Steve Ebersole Priority: Minor Fix For: 3.5.0-Beta-3, 3.3.x Original Estimate: 5 minutes Time Spent: 15 minutes Remaining Estimate: 0 minutes We override a lot of our Hibernate types to support Dual databases. Ive come upon a bug with boolean Primitives types wich lead me to this part of code in BooleanLiteralNode. Why casting the type in this method to BooleanType instead of the interface LiteralType? Its used internally and for the objectToSQLString() method anyway, for getRenderText(). {code} public String getRenderText(SessionFactoryImplementor sessionFactory) { try { return getTypeInternal().objectToSQLString( getValue(), sessionFactory.getDialect() ); } catch( Throwable t ) { throw new QueryException( "Unable to render boolean literal value", t ); } } {code} This lead to a hidden ClassCastException because our boolean custom type inherits AbstractType and implements the interfaces. {code} public BooleanType getTypeInternal() { return ( BooleanType ) getDataType(); } {code} Looks like some more people loose time with this.
