Issue Type: Bug Affects Versions: 6.0.2, 6.1.7 Assignee: Unassigned Components: hibernate-orm-modules Created: 27/Mar/2023 03:28 AM Environment: Java 17 Priority: Major Reporter: 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,
FileVersion version = new FileVersion();
version.setId("1");
version.setFileSize(100L);
version.setCheckSumMD5("ABCDEF");
version.setVariantName("A");
change all fields of the existing database entry (see testcase *testWithDynamicUpdate* )
version.setCheckSumMD5("XXXXXXXX");
version.setVariantName("B");
version.setFileSize(200L);
The following update statement will be created
Hibernate: update Versionen set CHECKSUM=?, FILESIZE=? where VERS_NUMMER=?
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
Arrays.sort( attributeNames );
attributeName = {checkSum, fileSize, variantName}
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:
attributeMappings = {AbstarctVersion.checksum, AbstractVersion.variantName, FileVersion.fileSize}
The for loop does only recognize the fields *checksum* and *fileSize. variantName* will not be processed.
