View source for Assign actions a menu group based on class

The scenario is that many classes based on a superclass has Class actions that all should have the same Menu Group.

This OCL will list all classes with a named superclass and list the class actions and their Menu Group
 Class.allInstances->select(c|c.AllSuperClassesAndSelf->includes(Class.allInstances->select(c|c.Name='PeWork')->first)).ClassActions->collect(ca|ca.Name, ca.MenuGroup.Name)
Replace 'PeWork' in the example above to the class or superclass you want to find

The EAL code will update the Menu Group to a named one.
 Class.allInstances->select(c|c.AllSuperClassesAndSelf->includes(Class.allInstances->select(c|c.Name='PeWork')->first)).ClassActions->forEach(ca|ca.MenuGroup := MenuGroup.allInstances->select(mg|mg.Name='PE')->first)
Replace 'PeWork' in the example above to the class or superclass you want to find and 'PE' to the existing Menu group you want to set.
