The problem if you use #error is that the error message is not user
friendly. Using MAError display just a few lines in top of your form.
Use doValidate instead of validat which doesn't exist :-) sorry
YourCommand>>validate
MAValidationError on: self
Or one of the subclasses
Are you really sure about this?
- I can see no #validate in the command hierarchy, #exceute still
sends #doValdiate
- MAValidationError is abstract
- PRRemoveCommand >> #doValidate
super doValidate.
(self structure isRoot)
ifTrue: [ self error: 'Unable to remove root node.' ].
#error: is the one from Object
