In Teacher Edit, 'Undo Changes' fails when done twice [2020:O]

[Brian Lewis]

Click Edit to go into Edit mode, . Undo Changes returns to not-editing mode.

Repeat this process and Undo changes does not return to non-eiting mode.

‌

This may be a broader problem than in Teacher form?

[Ghislain Hachey]

@Brian Lewis Actually the behavior I see is different. The first undo never works and does a save. Subsequent undos seem to work as expected.

[Brian Lewis]

The first Undo doesn't save - but does not reset the edited values on the model in memory.

Changing this to reread the object from the server in the event of undo - probably the safest approach?

For a New object, call getNew() again
