makeUniqueKeyFunction is not called for first node of a template

It sounds like your new node data object already has a key property declared on it. Search for "key" in your sources.

When loading a node data object, if the key is not undefined and is already unique, it is kept and the Model.makeUniqueKeyFunction should not be called. After all, if you are loading data that already has keys defined, you would not want to replace them with new keys, thereby losing information from the model.

Note how everything seemed to work well once you used a different Model.nodeKeyProperty name. That is because none of the node data objects already had values for that property.

By the way, the Model.makeUniqueKeyFunction does not need to modify the data object. This should also work:

model.makeUniqueKeyFunction = function() { return new UUID(4).format(); };
