Vaadin 无缓冲网格不会关闭

Question

I am having a weird problem on my Vaadin app. I have a screen with two separate unbuffered grids. The user is able to edit the data in those two grids and then click a "Save" button to save the changes made. My problem is that I want to close the editors when the user clicks on "Save". I tried the following code:

private void closeEditors() {
    if (tab1.getEditor().isOpen()) {
        tab1.getEditor().closeEditor();
    }
    if (tab2.getEditor().isOpen()) {
        tab2.getEditor().closeEditor();
    }
} 

I don't understand why this code doesn't work, editors stay opened. I also tried calling the cancel method but in vain. I am using Vaadin 14. I am posting this here with not much hope of finding an answer, this problem seems really precise. But with any luck, maybe someone has experienced a similar issue? Maybe there is another glitchier way of forcing my editors to close?

Any suggestion would be of great help, thanks in advance for anything you could think of !

EDIT: a little more code
This is the grids:

private Grid<Map<String, String>> tab1;
private Grid<Map<String, List<String>>> tab2;

This is the save function

public void saveData() {
    saveDataFromTab1();
    saveDataFromTab2();

    try {
        ServicesProxyImpl.getInstance().updateInBD(someObject);
        saveButton.setEnabled(false);
        cancelButton.setEnabled(false);
        closeEditors();

        Dialog dialog = VaadinComponentUtils.generateDialog(Constantes.MSG_SAVE_OK);
        dialog.open();
    } catch (JAXBException e) {
        e.printStackTrace();
        Dialog dialog = VaadinComponentUtils.generateDialog(Constantes.MSG_SAVE_KO);
        dialog.open();
    }
}

And this is the save button:

public Button getSaveButton() {
    Button saveButton= VaadinComponentUtils.generateButton("Save",
            VaadinIcon.CHECK_CIRCLE_O, null, true);
    saveButton.setEnabled(false);
    saveButton.addClickListener(event -> saveData());

    return saveButton;
}

EDIT 2:
I have noticed something, when I click on an element of one of my two grids, I want the editor to open for that specific element and I want to close the editor on the other grid (the one not concerned by the modification).
This works. My grids behave like I want.
It seems I am only losing control over my editors after I have actually modified one of the cells and clicked on my save button.
The isOpen function returns false on both grids after I call my closeEditors function, so it seems the grid thinks its editor is closed but it is still opened on my UI.

EDIT 3: I have found a workaround
Well, I have solved my problem by adding a close event listener on both my grids and calling resetGrids when the close event is fired. This function simply removes the grids from the UI, fetches the data to be displayed and then adds the grid one again, both editors being closed.
I guess it solves my problem but I would have wanted to understand what was going on...

    private void closeEditors() {
        tableauHoraires.getEditor().addCloseListener(e -> resetGrids());
        tableauRamassagePorteAPorte.getEditor().addCloseListener(e -> resetGrids());
        if (tableauRamassagePorteAPorte.getEditor().isOpen()) {
            tableauRamassagePorteAPorte.getEditor().closeEditor();
        }
        if (tableauHoraires.getEditor().isOpen()) {
            tableauHoraires.getEditor().closeEditor();
            tableauHoraires.getEditor().refresh();
        }
    }

Answer 1

Make sure that the objects in your grid have proper equals and hashcode methods and that the field(s) being edited do not influence them.

I use the PK from the database.
