/*
 There are 4 modes that this form can be in: 
  1.  Add, there is a subject and a predicate but no position and nothing else. 
        
  2. normal edit where everything should already be filled out.  There is a subject, a object and an individual on
     the other end of the object's core:personInOrganization stmt. 
  
  3. Repair a bad role node.  There is a subject, prediate and object but there is no individual on the 
     other end of the object's core:personInOrganization stmt.  This should be similar to an add but the form should be expanded.
     
  4. Really bad node. multiple core:personInOrganization statements.
