Hello.
my problem I think is related as the suggestion here, I am unable to create a custom variable:
I edited the jbpm.variable.types.xml and added my class (basically just pointed the serializable line to my class which is a exact copy of the BlobVariable)

But even so it says:

org.hibernate.HibernateException: instance not of expected entity type: org.jbpm.pvm.internal.type.variable.Blob64Variable is not a: org.jbpm.pvm.internal.type.Variable

Iam using v4.3, If I made exact copy of the BlobVariable, how come it does not work?
(I also teste extending BlobVariable instead of directly Variable, but still no success)
