Hi,

I have a list of a specified entity.
I would like to intercept modification to create new entity.

Now, I use the onChange event to run action-method. It works. I success to create a new object, but I cannot save it. This is the given error when save :

My code :

public void myAction(ActionRequest request, ActionResponse response) {
     MyObjectRepository repo = Beans.get(MyObjectRepository.class);
     Map<String, Object> contentOfObject = new HashMap<>();
     MyObject obj = repo.save(repo.create(contentOfObject)); // (this line create error)
}

have you annotated it with @Transactional ?? also the repo file is added in module to replace default repo ?

3

Annotated what ? the method ?
I was using default repo

4

I find something (which not fully solve my problem) :

JPA.runInTransaction(() -> {
     repo.save(repo.create(contentOfObject));
});

This save the object in DB, and if I refresh the page, hey will be showed. But, I have to refresh the page:

  • the main object is not showed as saved
  • in the relation field, there is a field which correspond at an object which have not be saved, but if I save the main object, it will replace my own object that I create before.

The transaction operations should be done in a service, not in a controller.

On this service, you can simply add the @transactionnal annotation on your method.

Ok so I have to do it when I run an event and not an action ?

And I found something which works :

  1. Use JPA.runInTransaction()
  2. Edit field thanks to response.setValue()

response.setValue() can be used to return a value to the view, then the user have to save manually the record.

@Transactional method can be used to save a change in database, then need to use response.setReload(true) to update the context of the view.
