Holger Bach ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=642158a... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiN2VkMmYzMDc5... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16379?atlOrigin=eyJpIjoiN2VkMm... ) HHH-16379 ( https://hibernate.atlassian.net/browse/HHH-16379?atlOrigin=eyJpIjoiN2VkMm... ) @DynamicUpdate and 'enableDirtyTracking=true' leads to wrong update statement ( https://hibernate.atlassian.net/browse/HHH-16379?atlOrigin=eyJpIjoiN2VkMm... ) Change By: Holger Bach ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=642158a... ) When updating an derived entity containing several field, not all changed fields will be updated Having a base entity containing two fields named *checksum* and *variantName* and a derived entity containing one field named *fileSize*. Create an database entry, {noformat}FileVersion version = new FileVersion(); version.setId("1"); version.setFileSize(100L); version.setCheckSumMD5("ABCDEF"); version.setVariantName("A");{noformat} change all fields of the existing database entry (see testcase *testWithDynamicUpdate*) {noformat}version.setCheckSumMD5("XXXXXXXX"); version.setVariantName("B"); version.setFileSize(200L);{noformat} The following update statement will be created {noformat}Hibernate: update Versionen set CHECKSUM=?, FILESIZE=? where VERS_NUMMER=?{noformat} Only *checksum* and *fileSize* will be updated, but not the field *variantName*. Problem occurs in file *AbstractEntityPersister* in function *resolveDirtyAttributeIndexes*. ch The dirty fields will be sorted bei name {noformat}Arrays.sort( attributeNames ); attributeName = {checkSum, fileSize, variantName}{noformat} In the for loop the fields in *attributeNames* will be compared to the array *attributeMappings*, which contains the mapping informations according to the annotations. *attributeMappings* has the following order: {noformat}attributeMappings = {AbstarctVersion.checksum, AbstractVersion.variantName, FileVersion.fileSize}{noformat} The for loop does only recognize the fields *checksum* and *fileSize. variantName* will not be processed.
