many-to-one in a properties element causes strange PropertyValueException on flush ---------------------------------------------------------------------------------- Key: HHH-2075 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2075 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr4 Environment: HSQLDB Hibernate r10478 Reporter: Josh Moore Attachments: exception.txt, log.txt, properties.zip Full test directory zip (org/hibernate/test/properties) attached. But to summarize, the following test will fail on flush after a simple merge. The exception thrown says that Pixels.sizeC is null -- though it's clearly set in the test case. <code> Image i = new Image(); Pixels p = new Pixels(); p.setSizeC(new Integer(2)); p.setImage(i); // This calls i.getPixels().add(p) // i.setPixels(null); // This makes it work. Session s = openSession(); Transaction t = s.beginTransaction(); // s.merge(i); // This makes it work. p = (Pixels) s.merge(p); // This fails with the exception below. t.commit(); s.close(); </code> The properties element in question is: <code> <properties name="defaultPixelsTag"> <property name="defaultPixels" type="java.lang.Boolean"/> <many-to-one name="image" class="Image" column="image" not-null="true" unique="false" insert="true" update="true" cascade="lock,merge,persist,replicate,refresh,save-update" /> </properties> </code> The reverse side is: <code> <set name="pixels" lazy="true" inverse="true" cascade="lock,merge,persist,replicate,refresh,save-update"> <key column="image" not-null="false"/> <one-to-many class="Pixels"/> </set> </code> -- 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
