[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-599) Hibernate cannot correctly load Locale in a @EmbeddedId key

Hibernate cannot correctly load Locale in a @EmbeddedId key ----------------------------------------------------------- Key: HSEARCH-599 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-599 Project: Hibernate Search Issue Type: Bug Components: engine Affects Versions: 3.2.1 Environment: hibernate-3.5.6 , hibernate-search-3.2.1 , lucene-2.9.3 , Spring-3.0.4 Reporter: Smallufo Huang Attachments: wrong.gif The whole description (with pretty code formatting) is in this thread : http://stackoverflow.com/questions/3825729/hibernate-search-unable-to-loa... To make it clear , I found an @EmbeddedId cannot correctly load Locale property! Suppose I have an @EmbeddedId with an integer and a locale , composing a composite primary key. And if the locale column in DB is storing "zh_TW" , it should build a Locale("zh" , "TW") object , with language=zh , country=Taiwan. But the loaded locale is language="zh_tw" , without country value! It will invalidate the equals()/hashCode() contract. And lucene will log "Object found in Search index but not in database" ! But if I remove the @EmbeddedId and use a surrogate key , the locale can be loaded correctly ! So it is a bug , but I am not sure it is from hibernate or hibernate-search.
