LDEV-4184: "outer-join" attribute in hbm.xml files is deprecated and produces warnings on server start up. Remove entries with "auto" value. Entries with value "true" become fetch=join.
LDEV-3293: fix hibernate dtd declarations. Change 'hibernate.org' to 'www.hibernate.org'.In order for hibernate DTDEntityResolver not to load hibernate-mapping-3.0.dtd from internet (and use local one), namespace declaration of dtd must exactly match the namespace declared in DTDEntityResolver class.
LDEV-3293: Use Spring support for Hibernate 4 instead of 3 (session factory and filters). Use new path for Hibernate DTDs. Make XDoclet generate hbm.xml files with the correct path by providing it a new template.
LDEV-2374: Vote tool does not "freeze" nominations the moment the first Learner reaches the activity. Nomination list can be extended by further inputs from previous tools.
LDEV-2374: - Vote now accepts nominations created by Teacher as well as ones derived from input. - Teacher can now limit number of Learners contributing to Vote's nomination pool. - Each tool now declares which DataOutputDefinitions it can accept for Data Flow.
LDEV-1597: Added new advanced object ShowResults, which controls whether or not the full results are shown. The user can still see their votes in export portfolio and if they return to the voting screen.
