> 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
