UML-B notes for 2.1.0

Unsolved from previous versions

Machine level diagram elements can be dragged into Classes

Problem - Machine level variables, events, statemachines can be dragged into the corresponding compartment of a Class. Once there it is difficult to remove them again.

Workaround - Avoid doing it in the first place. If necessary delete the element and recreate it.

Minor bugs

Inverse function ~ doesn't work with dot notation. Use normal event-B notation instead.

Diagram and Event-B file names are not changed/deleted if model is altered directly from EMF editors or model tab of properties view

Machine variables cannot be retained in refinement without repeating their type invariant
