How to prevent user from copying/duplicating collection reference such as notebook and experiment reference?
Please see E-Notebook Administrator's Guide -> E-Notebook Configuration -> Collection Types -> Configuring Collection Types -> Contained Reference Types. If there is no contained reference of a child collection type (e.g. Experiment) configured for a parent collection (e.g. Notebook), users cannot paste references to child (Experiment) under parent (Notebook) in the collection tree.
Users will still be able to paste references into a table (or into a property list), unless you configure Block Reference In State table listener (Block Reference In State property list listener). Please refer to the E-Notebook Administrator's Guide for more information (just search by the listener name).
