Child node types restriction settings?

[polymed]

Hi guys,

Is it possible to limit which child node types a node can have?

For example: Class A can only have Child Nodes of Type Class A

Best regards

It's not possible in the UI out of the box, but with Event Listeners on Data Objects (my guess is PRE_ADD and PRE_UPDATE) you should be able to inspect the object with getParent() and handle it from there to allow or not.

I thought so, thank you very much
