[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4966) Entity Manager bug with ParameterExpressionImpl

Entity Manager bug with ParameterExpressionImpl ----------------------------------------------- Key: HHH-4966 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4966 Project: Hibernate Core Issue Type: Bug Components: entity-manager Affects Versions: 3.5.0-CR-1, 3.5.1 Reporter: jean-claude cote Assignee: Steve Ebersole Fix For: 3.5.2, 3.6 Time Spent: 2h 34m Remaining Estimate: 0h Emmanuel There seems to be a bug with the ParameterExpressionImpl class when rendering. If you create a criteria query using a ParameterExpression instance in multiple places in your query the rendering of this query will produce multiple pram0, param1, param2 for the same ParameterExpression instance. We fixed this bug by augmenting the RenderingContext interface with generateParameterName(Expression<?> exp). With this information the rendering context can give back the same jpaqlParameterName for the same ParameterExpression instance. All it has to do is do a lookup in its explicitParamtermapping map. Thanks Jean-Claude
