Caused by: com.haulmont.cuba.core.global.RemoteException: During synchronization a new object was found through a relationship that was not marked cascade PERSIST: com.haulmont.bpm.entity.ProcInstance-941cec4a-35f3-7317-2529-1189ff59213f [new,managed,detached].

i just dataManager.commit(entity);

i konw why, because the entity incloud the entity ProcInstance-941cec4a-35f3-7317-2529-1189ff59213f ,
but the ProcInstance entity is no PERSIST,
but why is no PERSIST?
