David T. Lewis uploaded a new version of System to project The Trunk: http://source.squeak.org/trunk/System-dtl.961.mcz
==================== Summary ====================
Name: System-dtl.961 Author: dtl Time: 2 August 2017, 9:22:02.611529 am UUID: 4485dae2-bb1b-48ca-bdc1-5f1f4dd89eb0 Ancestors: System-eem.960
When Project class>>tryOtherProjectForRecovery is searching for a safe project to use for emergency recovery, test for projects of a type that the current project inherits from, but do not require that they be of the same class. This handles the case of errors in a FooMorphicProject that inherits from MorphicProject, for which another Morphic project is not likely to be suitable for handling a fatal error raised in the FooMorphicProject.
Expected behavior when evaluating "Project handlePrimitiveError: 'Foobar' "
In an MVC project that is a chlid of a Morphic project, enter the Mophic project and open a debugger on the process that failed in MVC.
In a Mophic project that is a chlid of an MVC project, enter the MVC project and open a debugger on the process that failed in Morphic.
For the common case of a parent project of the same type as the project from which the error is raised, do not attempt to enter another project, and open an emergency evaluator instead.
