Andi Huber closed ISIS-1960.
----------------------------
Resolution: Fixed
Was superseded by the ServerSentEvent (SSE) extension.
We also enabled async execution for the WrapperFactory, which is the place to
look now when anticipating simple background task execution.
> Action background execution: provide built-in default implementation

> Project: Isis
> Issue Type: Improvement
> Components: Core
> Reporter: Andi Huber

> Priority: Major
> Fix For: 2.0.0
>
>
> 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 BackgroundService backgroundService;
> @Inject RepositoryService repositoryService;
> @Inject MessageService messageService;
> @Action
> public SimpleObject runInBackground(){
> backgroundService.execute(this).backgroundTask();
> return this;
> }
>
> @Programmatic
> public void backgroundTask(){
> messageService.informUser("backgroundTask started");
> try {
> Thread.sleep(8000); // wait 8s
> } catch (InterruptedException e) {
> e.printStackTrace();
> }
>
> val dummy = new SimpleObject();
> dummy.setName("Dummy");
>
> repositoryService.persist(dummy);
>
> messageService.informUser("backgroundTask finished");
> }
> {code}
> We solve this using a default ExecutorService to run Action invocations in
> the background.
