[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3090) Error when executing polymorphic queries with limits

Error when executing polymorphic queries with limits ---------------------------------------------------- Key: HHH-3090 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3090 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5, any database Reporter: Jaime Porras Attachments: HQLQueryPlan.diff, test-polymorphic.tar.gz Original Estimate: 10 minutes Remaining Estimate: 10 minutes When a polymorphic search is performed HQLQueryPlan.performList() never return any results because there is a mistake in this code: for ( int x = 0; x < size; x++ ) { final Object result = tmp.get( x ); if ( distinction.add( result ) ) { continue; } includedCount++; if ( includedCount < first ) { continue; } combinedResults.add( result ); if ( max >= 0 && includedCount > max ) { // break the outer loop !!! break translator_loop; } } The call to distinction.add( result ) returns true when the result is added and false when the result is already in the set. So the if code should be: if ( !distinction.add( result ) ) { continue; }
