Hi, Is there a way I can add a colum to a jbpm4.3 table (i.e. EXPIRE_DATE_ to  JBPM4_TASK or JBPM_HIST_PROCINST) and extend the impl class that manage it?

I would avoid to modify the class but just extend it (i.e. MyCustomTaskImpl or MyCustomProcessInstanceImpl) and make it to be used by jbpm..

thank you.
