Anybody having an opinion on 1. whether XUndoManager.undo/redo, when invoked while an Undo context is open, should a. throw b. silently and implicitly close all open contexts c. ignore the call d. other? 2. whether XUndoAction.undo/redo should be allowed to raise exceptions (except the always-possible RuntimeException)? 3. how to deal with XUndoAction.undo/redo throwing an exception? a. silence the error? b. propagate the error to the caller of XUndoManager.undo/redo c. clear the respective stack, since obviously the top action cannot be invoked, thus the other actions, which may depend on the top action, also can't d. both b. and c.I tend to 1a., 2-yes, and 3d., but would appreciate any opinion on this.
IIUC, 1a means throwing for a temporary failure, so 3c appears to be too aggressive?
Also, question 2 should rather be "what exceptions exactly should be raised," right?
