UML-B notes for 2.1.0
New problems in version 2.1.0
Model Elements with Errors will not be deleted
Problem - When an element has errors, a notification is generated when the user tries to delete it. This causes the model to be reloaded before the deletion completes.
Workaround - a) Fix errors before deleting or b) Open the *.umlb model file and delete the element from within the EMF editor.
Plan - Fix in next version (due Feb 2011).
Unsolved from previous versions
No way to manually contribute to the INITIALISATION event
Problem - The INITIALISATION event is automatically generated and there is no way to contribute to it.
Workaround - None
Plan - Fix in next version (due Feb 2011).
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
