[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2900) Autodiscovery results ignored by scroll()

Autodiscovery results ignored by scroll() ----------------------------------------- Key: HHH-2900 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2900 Project: Hibernate3 Issue Type: Bug Components: query-hql, query-sql Affects Versions: 3.2.4.sp1 Reporter: Sergey Koshcheyev Priority: Minor Running this piece of code: session.createSQLQuery("create table tab(col integer)").executeUpdate(); session.createSQLQuery("insert into tab values (1)").executeUpdate(); ScrollableResults sr = session .createSQLQuery("select col from tab") .addScalar("col") .scroll(ScrollMode.FORWARD_ONLY); sr.next(); sr.getInteger(0); produces java.lang.NullPointerException at org.hibernate.impl.AbstractScrollableResults.getFinal(AbstractScrollableResults.java:126) at org.hibernate.impl.AbstractScrollableResults.getInteger(AbstractScrollableResults.java:208) The problem seems to be Loader.scroll() is using its returnTypes parameter when instantiating ScrollableResultsImpl instead of letting CustomLoader use its autodiscovered resultTypes array. A workaround seems to be to use ScrollableResults.get(int) since it doesn't rely on type information. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
