             Summary: Action background execution: provide built-in default 
implementation
                 Key: ISIS-1960
                 URL: https://issues.apache.org/jira/browse/ISIS-1960
             Project: Isis
          Issue Type: Improvement
          Components: Core
            Reporter: Andi Huber
            Assignee: Andi Huber
             Fix For: 2.0.0-M1


We want this code to run out-of the box (without the need for developers to 
provide their own implementation of *BackgroundCommandService*) ...
{code:java}
@Inject private BackgroundService2 backgroundService;

@Action
public SimpleObject runSlowlyInBackground(){
        backgroundService.execute(this).runSlowly();
        return this;
}
    
@Action
public SimpleObject runSlowly(){
        try {
                Thread.sleep(8000); // wait 8s
        } catch (InterruptedException e) {
                e.printStackTrace();
        }       
        
        val dummy = new SimpleObject();
        dummy.setName("Dummy");
        
        repositoryService.persist(dummy);
        
        return this;
}
{code}

We solve this using a default ExecutorService to run Action invocations in the 
background.
