             Summary: To avoid leaky abstractions, a mixin collection should 
only ever emit collection domain events; ditto for properties.
                 Key: ISIS-3239
                 URL: https://issues.apache.org/jira/browse/ISIS-3239
             Project: Isis
          Issue Type: Improvement
    Affects Versions: 2.0.0-M8
            Reporter: Daniel Keir Haywood
            Assignee: Daniel Keir Haywood
             Fix For: 2.0.0-RC1


For mixins, currently the ActionInvocationFacetForDomainEventAbstract , which 
invokes the action and emits events, only ever emits an ActionDomainEvent for 
all types of mixins.  

But it doesn't look at the @Action, @Property or @Collection annotations on the 
class.

Instead, it should first look at the class level if on of those annotations 
defines an domain event and when it doesn't then look at the method level.

NB: this takes care of executing, executed ... think there will be some other 
code impacted for hide, disable, validate.
