Dirty check fail for CharArrayType ---------------------------------- Key: HHH-4110 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4110 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Reporter: Maillefer Jean-David Entity fields of type char[] are mapped using class org.hibernate.typeAbstractCharArrayType. These fields are always marked dirty by the dirty check mechanism and thus are always updated to the database. The dirty check implementation uses inherited org.hibernate.type.NullableType#isEqual(Object, Object) which in turn call org.hibernate.util.EqualsHelper.equals(Object, Object) which does only a reference check for array, not a "deep" check similar to Arrays.equals(char[], char[]). I suggest overriding #isEqual(Object, Object) in AbstractCharArrayType with the following code (adapted from EqualsHelper) : public boolean isEqual(Object x, Object y) { return x==y || ( x instanceof char[] && y instanceof char[] && Arrays.equals((char[])x, (char[])y) ); } -- 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
