I have following 2 entities
{quote}
{{ @Entity
public class Module {
@Id
Integer id;
String moduleName;
...
@OneToMany(mappedBy = "module")
List<Version> versions;
...
}
@Entity
public class Version {
...
@ManyToOne
@JoinColumn(name = "moduleName", referencedColumnName="moduleName")
Module module;
...
}
{quote } }
TransientPropertyValueException is thrown when I save instance of Version entity as follows:
{quote}
Module m = new Module(); // id is unknown!
m.setModuleName("core");
Version v = new Version();
v.setModule(m);
{quote}
TransientPropertyValueException message:
{quote}org.hibernate.TransientPropertyValueException: object references an unsaved transient instance - save the transient instance beforeQuery flushing : com.example.Version.module -> com.example.Module{quote}
This module "core" is already in database.
I think, it should check by referenced column when it is referenced by custom column
Detail of stack tracle:
