[Pellet-users] addInverseProperty() exception

[Tiziano Furlan]

Here is the code I'm using:

kb.addProperty(ATermUtils.makeTermAppl(pName.toString()));
Role r = kb.getRBox().getRole(ATermUtils.makeTermAppl(pName.toString()));
r.setType(Role.OBJECT);

done for both properties. After that I search for p1 and p2 ciclying on 
kb.getProperties() and then

kb.addInverseProperty(p1, p2);

that gives the exception.
