[jboss-user] [jBPM] - Invalid JPA definition for ProcessInstanceLog v5.4.0, leads to Hibernate exception

I see that the ProcessInstanceLog class has been modified between 5.3.0 and 5.4.0. The following persistent properties have been added: @Column(nullable=true)private int status;@Column(nullable=true)private long parentProcessInstanceId;@Column(nullable=true)private String outcome; However, I think having a nullable property with a primitive type is not going to work when loading data with the "parentProcessInstanceId" or "status" having null values (which happens in my case). Hibernate complains: Caused by: java.lang.IllegalArgumentException: *Can not set long field org.jbpm.process.audit.ProcessInstanceLog.parentProcessInstanceId to null value*     at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146)     at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:150)     at sun.reflect.UnsafeLongFieldAccessorImpl.set(UnsafeLongFieldAccessorImpl.java:62)     at java.lang.reflect.Field.set(Field.java:657)     at *org.hibernate.property.DirectPropertyAccessor$DirectSetter*.set(DirectPropertyAccessor.java:139) I think a simple fix would be to substitute int with Integer, long with Long, and modifiy the setter/getter methods accordingly. Am i the only one with the problem? Should I open an issue on Jira? Thanks for your help. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/795008#795008] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
