Re: [Pharo-users] Latest Pharo 7 image doesn't give normal debugger on a method with undefined class method - get System Error

by Tim Mackinnon

Excuse the noise - this was user error, I synchronised my Pharo repository with an out of date local copy, so I must have brought in some incompatible changes with the new VM. Phew !

Latest Pharo 7 image doesn't give normal debugger on a method with undefined class method - get System Error

by Tim Mackinnon

I was going to look at testing my Create class in the debugger fixes however the latest image behaves in a manner Iâve not seen before. In a fresh P7 image - build 1198 64bit osx (with latest vm downloaded by launcher) - I have created a new class in a new package TimTest:TimTest>>testMethod "self new testMethod" FooObject new someMethod Where FooObject and someMethod are undefined and when I saved the method I left them as undefined. I then evaluated - TimeTest new testMethod in a playground and I get a white screen with *** System error handling failed *** (screenshot below) In an earlier image (build 1167) this wasnât the case? Has something been broken? Tim
