fetch="select" doesn't work when there are no mapped columns in joined except <key ---------------------------------------------------------------------------------- Key: HHH-2546 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2546 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.3 Environment: Windows XP Pro Reporter: Derar Bakr java.lang.StringIndexOutOfBoundsException: String index out of range: -2 at java.lang.String.substring(String.java:1768) at java.lang.String.substring(String.java:1735) at org.hibernate.persister.entity.AbstractEntityPersister.renderSelect(AbstractEntityPersister.java:2899) at org.hibernate.persister.entity.SingleTableEntityPersister.generateSequentialSelect(SingleTableEntityPersister.java:647) at org.hibernate.persister.entity.SingleTableEntityPersister.postInstantiate(SingleTableEntityPersister.java:696) .... Everything is very simple. There is stupid code in SelectFragment class, method toFragmentString, line 94. String that is being created there, contains list of fields, like a "f1, f2, f3, ..., fn". ", " is being added in every iteration, without check for it is first iteration. And in class AbstractEntityPersister., method renderSelect, line 2899, where that method is called, this first ", " is deleted using substring(2). So no check for empty string. I suggest to add check :))) I just create dynamic mappings programmatically, so create empty join subclass mappings - and in created table there are no fields by default except foreing key. -- 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
