Explicitly setting parent token label

I have a subflow activity where the Parent Label Access is set to Read. Thus the child token can not modify or create new labels on the parent token. However I am able to create a new label through custom code like this

token.parent.New_label = 356;

Is this supposed to be possible? and/or is this just simply left out in the documentation regarding parent/child relationships?

FlexSim 20.2.3

Yes, this is expected behavior. Setting the Parent Label Access is not really about encapsulation and preventing a child token from accessing things on the parent. It's more of an ease of use thing for determining what labels get accessed when you say token.MyLabel. On one end of the spectrum you give the token no access to parent labels so that all labels you read, write, or create using the token.LabelName syntax are on the child token. On the other end, the child token is just a proxy for the parent token and the token.LabelName syntax behaves exactly as if the child token were the parent token.

However, no matter what access you set, it's expected that if you explicitly access the parent token with token.parent then you have full access to the parent's labels.

Thanks! I’ve been struggling with some logic regarding split/join/batches and no preprogrammed activity settings seemed to suit my situation, i.e. until l found out that you can explicitly set parent token labels.
