You were right with your explanation.Groups and limitation is one area which we have jotted down for an enhancement.
So, just to restate... say I create a Yes/No node property named "Houston" and set a list of ten nodes to True. I also create an account limitation by the same name.
Then, I dynamically create a Group named Houston using the custom property in the query.
If I understand correctly, it is normal functionality, for now, that if I add the account limitation of Houston and the account limitation of a Single Group = Houston, that the Node tree and the Group Summary page will both show only nodes that are in Houston and the Houston group. Right?
In the future, we hope to be able to have the node limitation and the Group limitation act independently of each other.
Have I got that all right?
