Hi Experts,
I have a questions about avoiding duplicates nodes or leaf elements in a tree structure.
The hierarchy data is retrieved from a RFC. Then the data retrieved is applied to the tree structure as the user expands a node individually. The user is then allowed to add new nodes and leaves to the structure.
If you have a recursive node in a context which is built at runtime depending on which node the user expands. When the user decides to add a new node or leaf, how can you prevent the user from creating new nodes and leaves which already exist within the hierarchy?
Thanks for reading.
Marshall.
