MAPersonModel>>nationality
^ nationality isNil ifTrue: [ nationality :='' ]
And why..
Thanks
Just a tip, try this pattern if you "need" to set the inst var...
nationality
^nationality ifNil:[nationality := '']
and this if you don't and always use the accessor regardless
nationality
^nationality ifNil:['']
