             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.
