[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-2295) entity-name attribute's syntax not clearly documented

entity-name attribute's syntax not clearly documented ----------------------------------------------------- Key: HHH-2295 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2295 Project: Hibernate3 Issue Type: Bug Components: core, documentation Affects Versions: 3.2.1 Environment: Windows XP/JDK 1.5/HypersonicSQL Reporter: Jeremy Michael Crosbie Priority: Minor Attachments: Group.hbm.xml Setting entity-name to a value containing a hyphen, in my case 'lender-group' causes odd behaviors seemingly only when calling get() or load(). Also in my case I am mapping a class to two different tables (attached). The first mapping has an entity name with a hyphen, the other does not. When I call load *after committing a transaction where a new entity is persisted* I get an exception (see below). The exception complains of a column called "LENDER" not existing. But once I change the entity-name to something like 'lendergroup' the problem goes away. Interestingly, the missing column complained about is the text before the hyphen, so if I name the entity 'lndr-group' it complains of a column name 'LNDR' not existing. It almost appears if this format is assuming some sort of discriminator, but the online docs are terse when it comes to describing the entity-name field.
