NPE thrown when trying to sort domain with composite ID
- Operating System: Windows 10
- GORM Version: 7.0.1 (
org.grails.plugins:hibernate5:7.0.1) - Grails Version (if using Grails): 4.0.0.RC2
- JDK Version: 8
Given the following domains:
class ExampleRole {
String name
static constraints = {
}
}
class ExampleUser {
String name
static constraints = {
}
class UserRole implements Serializable{
ExampleUser user
ExampleRole role
static mapping = {
id composite: ['user', 'role']
}
static constraints = {
}
}
If you attempt to call the following method, there will be a NullPointerException thrown
UserRole.list(sort: "role")
The code causing the issue is line 306 of GrailsHibernateQueryUtils:
if (sort.equalsIgnoreCase(entity.getIdentity().getName())) {

I investigated a bit further.
I made another domain which did not reference other domains and just had a composite key.
class Composite implements Serializable{
String field1
String field2
Integer sequence
static constraints = {
}
static mapping = {
id composite: ['field1', 'field2']
}
@Override
String toString(){
"$field1 $field2"
}
}
This domain exhibited the same behavior.
So, I started to experiment with the code myself. I did a null check on the line that was bombing and got a deeper Hibernate error.
I changed this line (line 306 in GrailsHibernateQueryUtils):
if (sort.equalsIgnoreCase(entity.getIdentity().getName())) {
to this:
if (entity.getIdentity() != null && sort.equalsIgnoreCase(entity.getIdentity().getName())) {
This actually does fix sorting on a non-identifier field, like if I change the composite domain in the original example to this:
class UserRole implements Serializable{
ExampleUser user
ExampleRole role
Integer sequence
static mapping = {
id composite: ['user', 'role']
}
static constraints = {
}
}
With the null check in place, UserRole.list(sort: "sequence") will work correctly, but UserRole.list(sort: "role") will still throw an exception, this time in Hibernate itself.

Were you able to resolve this?
I get a similar "IllegalArgumentException: Unable to locate Attribute with the the given name " when running the following query on UserRole
UserRole userRole = UserRole.createCriteria().get { user { eq("username", username) } role { eq("authority", Role.DEVELOPER) } }

No, we've managed to work around it for the sorting by doing things like UserRole.list().sort{it.role} which is obviously less than optimal.
That's interesting that createCriteria is triggering a similar issue. It appears that the way they map composite keys has changed but they didn't account for it in the hibernate translation layer.
I am also getting the IllegalArgumentException error. Attaching sample project that shows the problem in a test: Example project with test that shows the error
This affects any domain, that has a composite key and tries to use criteria. The workaround would be to implement the queries as HQL using executeQuery, findAll etc, but in unit tests you get "String-based queries like [executeQuery] are currently not supported in this implementation of GORM. Use criteria instead.", which can only be avoided by re-writing every affected unit test to use HibernateSpec and the BuildHibernateData trait, which is not a trivial exercise on any well-covered project. Thus this is blocker for anyone who has a composite key and is trying to upgrade to grails 4. Please prioritise this.
Note that the underlying error also appears, when using withCriteria:
UserRole.withCriteria {
user { // during runtime will give you the following exception
}
}
Caused by: java.lang.IllegalArgumentException: Unable to locate Attribute with the the given name [user] on this ManagedType [<yourpackage>.UserRole]
Somehow when the composite key is used, the elements of the composite key seem to be missing from here:
final Metamodel metamodel = sessionFactory.getMetamodel();
final EntityType<?> entityType = metamodel.entity("<yourpackage>.UserRole");
log.error("Registered attributes: " + entityType.getAttributes())
Will give you only the attributes, that are not part of the composite key. For me it looks like the underyling issue might be this one:
