[FlowUI] get calling action

mgiammarco1 · May 12, 2023, 6:21pm

Hi,
I have a listView that opens a DetailsView.
But in listview I have not only standard actions but more:

create
edit
copyFrom
newVersion

In the detail view I need to understand which action invoked me, how can I do it considering that I have created custom code only for my custom actions?
Thanks,
Mario

Basically I need to do:
if (calledFromCreate==true) { dosomething}
if (calledFromEdit==true) { do somethingelse}

Is there a way to pass a value from caller view to callee view?

Thanks,
Mario

Hi,

you have two options depending on the way you open a view:

in case of navigation, you can open a view with wither route parameters or URL query parameters, e.g.:

viewNavigators.detailView(User.class)
        .editEntity(entityToEdit) // .newEntity() in case of creation
        .withQueryParameters(QueryParameters.of("someParam", "someValue"))
        .navigate();

and handle these parameters:

@Subscribe
public void onQueryParametersChange(QueryParametersChangeEvent event) {
    // handle params
}

in case of opening a dialog window, you can create a setter method in your view and call this method before opening a dialog, e.g.:

DialogWindow<UserDetailView> dialogWindow = dialogWindows.detail(this, User.class)
        .withViewClass(UserDetailView.class)
        .editEntity(entityToEdit) // .newEntity() in case of creation
        .build();

UserDetailView view = dialogWindow.getView();
view.setSomeParameter("someValue");

dialogWindow.open();

since you want to handle create/edit actions, you have the third option - InitEntityEvent. This event is fired only if a view is opened for a new entity, so you can either do come logic in InitEntityEvent handler or set a flag that a view is opened for creation rather that editing.

@Subscribe
public void onInitEntity(InitEntityEvent<User> event) {
  // handle new entity creation
}

in addition, we provide the EntityStates bean, which provides information about entity states: is it new, is it managed, ect. For example UserDetailView uses it:

@Subscribe
public void onReady(ReadyEvent event) {
    if (entityStates.isNew(getEditedEntity())) {
        usernameField.focus();
    }
}

Regards,
Gleb

Thanks for reply,
is it possible to add queryparameters in standard actions?
In the way you suggest me I have to write code myself I cannot override/inherit CreateAction or EditAction execute method.
The best solution would be to add a queryparameter or a property to standard actions that is passed to callee.
Thanks,
Mario

gorelov · May 31, 2023, 7:21am

You can subscribe on ActionPerformedEvent of a corresponding action, thus overriding only its execute method.

mgiammarco1 · June 5, 2023, 3:50pm

I am still stopped.
I can subscribe to standard actions and custom ones.
Now I need to implement a “copy from” action.
I have read documentation, past forum replies and jmix ui samples and your example.
I am using Flow UI.
This code generate exception:

Ricoco copia=metadataTools.copy(ricocoesTable.getSingleSelectedItem());
        copia.setId(UuidProvider.createUuid());

viewNavigators.detailView(Ricoco.class)
        .editEntity(copia) // .newEntity() in case of creation
       
        .navigate();

I have also tried with newEntity() but it fails again.
Can you help me?
Thanks,
Mario

Hi,

What exception do you get?

mgiammarco1 · June 6, 2023, 9:19am

EntityAccessException: Unable to load entity ric_Ricoco-71679fc3-3391-60cf-5c3d-e9f9334c4109 because it has been deleted or access denied

if I use copia.setId(UuidProvider.createUuid());
or null pointer exception if I use copia.setId(null);
I suppose the problem is that when Jmix sees the id it tries to load the object.

That’s true, you need to save the copied entity before navigation to the detail view, or open it in a dialog using DialogWindows.

For navigation:

User selected = usersTable.getSingleSelectedItem();
if (selected == null) {
    return;
}

User copied = metadataTools.copy(selected);
copied.setId(UuidProvider.createUuid());
copied.setUsername(copied.getUsername() + RandomStringUtils.randomAlphabetic(3)); // username is unique
User saved = dataManager.save(copied);

viewNavigators.detailView(User.class)
        .editEntity(saved)
        .navigate();

For dialog:

User selected = usersTable.getSingleSelectedItem();
if (selected == null) {
    return;
}

User copied = metadataTools.copy(selected);
copied.setId(UuidProvider.createUuid());
copied.setUsername(copied.getUsername() + RandomStringUtils.randomAlphabetic(3)); // username is unique

dialogWindows.detail(this, User.class)
        .newEntity(copied)
        .open();

I begin to worry, I must not save anything in advance and I could not open a dialog.
Can I pass the “original” object to the destination view as a query parameter? I will try to copy it after the view is created.

in this case, I’d recommend passing an id of an entity you want to copy to the editor, load it, and copy its attributes to the new entity instance, e.g:

public class UserListView extends StandardListView<User> {

    @ViewComponent
    private DataGrid<User> usersTable;

    @Autowired
    private ViewNavigators viewNavigators;
    @Autowired
    private UrlParamSerializer urlParamSerializer;

    @Subscribe("usersTable.copy")
    public void onUsersTableCopy(final ActionPerformedEvent event) {
        User selected = usersTable.getSingleSelectedItem();
        if (selected == null) {
            return;
        }

        viewNavigators.detailView(User.class)
                .newEntity()
                .withQueryParameters(QueryParameters.of("copy", urlParamSerializer.serialize(selected.getId())))
                .navigate();
    }
}

@Autowired
private MetadataTools metadataTools;
@Autowired
private DataManager dataManager;
@Autowired
private UrlParamSerializer urlParamSerializer;

private UUID copyId;

@Subscribe
public void onQueryParametersChange(QueryParametersChangeEvent event) {
    List<String> copy = event.getQueryParameters()
            .getParameters()
            .get("copy");

    if (CollectionUtils.isNotEmpty(copy)
            && copy.size() == 1) {
        copyId = urlParamSerializer.deserialize(UUID.class, copy.get(0));
    }
}

@Subscribe
public void onInitEntity(final InitEntityEvent<User> event) {
    if (copyId != null) {
        User entityToCopy = dataManager.load(Id.of(copyId, User.class))
                .one();

        User entityToEdit = event.getEntity();
        metadataTools.copy(entityToCopy, entityToEdit);

        copyId = null;
    }
}

Gleb

Thank you for solution, i just wanted you to know that compared to cuba or jmix v1 this is too overcomplicated.

scarfagna72 · July 25, 2024, 11:02am

Ciao Gianmarco,

Create custom button
Handle click event.

Try to use

    @Autowired
    private DataManager dataManager;
