Xml-persisted empty string are interpreted as null value -------------------------------------------------------- Key: HHH-2370 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2370 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.2 Environment: All hibernate version, on all platform. Reporter: Daniele Castagna Priority: Minor Attachments: HEmptyString.tar.gz NullableType.Object fromXMLString(String xml, Mapping factory) method returns null if the string is an empty string (string with a length of 0). This creates some problems when you use xml persistence to export or import empty string property with the not-null costraint. Look at the attachment simple project (or here: http://forum.hibernate.org/viewtopic.php?t=969755 ) for an example that will throw an unexpected exception. This problem could be easily fixed removing the "|| xml.length()==0" boolean expression from the fromXMLString method. I think that it would be better not only with strings but even with other types; for example an xml tag that should be interpreted as an Integer and contains an empty string should throw an exception, and should not return a null value. The null value is already represented by the absence of the xml tag. -- 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
