Re: CellTable - ListDataProvider - Table not updating on subsequent calls

Hi:

Apologize for the delayed response.

That sounds different to the issue I was running into. In my case I do recall the update working (server side) as well as the actual response over the wire. For me It was purely an issue of how the Store/List Provider was populated and shown in the UI widget with the latest response received from the server.

Best regards.

I actually found the underlying cause.  Basically on the second update I am getting an optimistic locking error.

But I am convinced I am using my JPA correctly.

Does that ring any bells or jog your memory?

Ufff it's been so long I can't remember :( sorry and on top of it I deleted the project. I just read my own email again to see if I could tell what I was doing wrong and even now can't really tell.

Hello Alfredo.  I am having a similar issue.  Did you get to the bottom of this?

Thanks

I am still investigating here on my side, but I have a feeling I might
be missing the obvious so if someone knows what I am missing or
potentially doing wrong please let me know.

Elements:

- A CellTable
- A ListDataProvider
- RequestFactory
- A "refresh" button

Scenario:

- The CellTable is populated via RequestFactory.
- On the first load, all data is shown in the table (all rows are populated)
- I have a button (refresh).
- The Table can be edited, so as an example I edit the first row,
first cell and simply change the text to something else.
- I click on the refresh button and load a brand new list of proxies
from the server using request factory.
- I clear my provider's list and add the new proxies.
- The new list doesn't replace the old values (previously edited).

Curiosity:

I've noticed that after I click refresh, although at first glance the
edited cell didn't change, if I click on it once or twice, it'll
correctly display the last value loaded from the server. This is very
unusual behavior. I've also tried to invoke refresh and flush on the
provider itself after adding the new set of proxies.

Presenter's code that is invoked for the first load and subsequent
ones is shown below:

        @Override
        public void readAll() {

                destinationContext = factory.getRequestFactory().createDestinationContext();
                destinationContext.findAll().with("cards", "cards.trunks",
"daysOfWeek", "daysOfWeek.hourlySchedule", "holidays")
                                .fire(new Receiver<List<DestinationProxy>>() {

                                        @Override
                                        public void onSuccess(List<DestinationProxy> proxies) {

                                                view.getDestinationCellTable().getProvider().getList().clear();
                                                view.getDestinationCellTable().getProvider().getList().addAll(proxies);

                                                if (proxies != null && proxies.size() > 0) {
                                                        view.getDestinationCellTable().getCellTable().getSelectionModel().setSelected(proxies.get(0),
true);
                                                }

                                        }

                                });

        }

I am still investigating here, but as I previously said if you see
that I am simply missing the obvious I would appreciate it if you can
let me know.

Thank you in advance,

Alfredo
