During the migration to MPS 3 all concept properties have been replaced by static behavior methods. This is fine in many cases but not in all. If you want to save a state at runtime inside the property you can't do this just with a method.
In my case I have used the property to save the decision if a property is displayed with a keyword or with an icon. With an action or intention the user could switch between the representations and this has effected all nodes with this property. I don't know how to implement this behavior again in MPS 3.0? Has anybody an idea?
