I currently have an active custom model, generated by xml and one of the types is currently applied to a node.
When attempting to modify the code definition of the model (adding an aspect), I can't save the changes:
1. Is this because the type is active and applied?
2. Is there a way to modify models while they are applied? - as only one file is using the model currently, it's not a problem, but when applied further this could cause some real issues down the line if the model needs to change.
