Role Changeability what is it?

[Paolo F Cantoni]

There's an item on the association Role Dialog marked Changeable.  The only help I can find for it is for

IsChangeable: Read/Write. Flag indicating this end is changeable or not.

 

Anyone know what exactly the three enumerates mean?
none
frozen
addOnly

As far as I can see the conceptual meaning should be something like:

Add,Shift,Delete       (Full)
Add,Shift                  (NoDelete)
Add                          (AddOnly)

Where shift means reconnect to another target.

It would appear you can't get at them through the CTF.

Cheerz,
Paolo

This looks like a variant. If the role can change you have to do prechecks which role is the current. Just a guess - I'm not a modeller...
