I still don't understand how I create a pagination

ERROR: View is already initialized, please move this method call to class construtor or #onInit.

[DevNatan]

@SrMinister States must be created before view initialization, onRender is called after view initialization. Move the paginationState to class top level as a final value

private final State<Pagination> paginationState = paginationState(
    (context) -> listFriends(context.getPlayer()),
    (item, friend) -> item.withItem(new ItemBuilder(Material.SKULL_ITEM).name("").build())
);

@Override
public void onInit(ViewConfigBuilder config) {
    config.title("Lista de amigos")
            .size(6)
            .layout(
                    "         ",
                    " OOOOOOO ",
                    " OOOOOOO ",
                    "         ",
                    "         ",
                    "         ")
            .cancelOnClick();
}

private List<Friends> listFriends(Player player) {
    return plugin.getUserCache().getByName(player.getName()).getFriends();
}

Did you remove the context in the new update?

-> (context) -> Lists.newArrayList(AnimatedHeadsType.values()) not exist context

private final State<Pagination> paginationState = paginationState(
        (context) -> Lists.newArrayList(AnimatedHeadsType.values()),
        (context, item, index, animatedHeadsType) -> item.withItem(
                new ItemBuilder(Material.SKULL_ITEM)
                        .texture(animatedHeadsType.getTexture())
                        .name(animatedHeadsType.getName())
                        .lore(
                                "§7Altere seu chapéu animado",
                                "§7para ficar no estilo.",
                                "",
                                "§aClique para alterar.")
                        .addFlag(ItemFlag.values())
                        .build()
        ).onClick(click -> {
            final Player clicker = click.getPlayer();
            final User user = userState.get(click);

            AnimatedHeadsTask.stop(clicker);
            AnimatedHeadsTask.startTask(clicker, animatedHeadsType);

            MessageProvider.ORB_PICKUP.sendMessage(

                    "§e§lGG! §eVocê acaba de selecionar o chapéu animado " +

@SrMinister paginationState with Function-like as sourceProvider parameter was removed. Use lazyPaginationState instead

Is there a way to use the spawner parameter on the current page to identify it as a state on another page?

            Discount discount = discountState.get(context);

            if (!context.getPlayer().hasPermission(spawner.getPermission())) {
                builder.withItem(
                        new ItemBuilder(Material.BARRIER)

@SrMinister Do you mean another view?

@SrMinister I'll take a look to find the cause of that NullPointerException

[DevNatan]

@SrMinister By default, the data is not transitioned entirely throughout the stream, that is, opening a screen with A initial data and navigating to B without declaring all data explicitly via openForPlayer, the data from A will not be accessible from B. I I will add an option to make this the default behavior. This is the cause of your error.

You can create a temporary workaround for this replicating the current data using context.getInitialData()

Map<String, Object> data = new HashMap<>();
data.put("spawners", spawner);
data.putAll((Map<String, Object>) click.getInitialData());
click.openForPlayer(StoreView.class, data);

[kaiquyricardo]

I saw that you updated the api, is it now possible to do this instead of creating a map? If so, could you explain it to me using the previous question?

@SrMinister This change was not planned to v3.0.0, will be available in v3.0.1 or v3.1.0 :pray:

[kaiquyricardo]

I cancel the click but I can't move the item in my inventory to drag it to slot 11 where the material is changed, in the past in previous libs I only had to activate the cancel click and nothing else, if I didn't want to drag it so, just add cancelOnClickPickup.

@SrMinister Please open a separate issue for this issue https://github.com/DevNatan/inventory-framework/issues/441#issuecomment-1739637918 so we can track it and resolve it better

[DevNatan]

I saw that you updated the api, is it now possible to do this instead of creating a map? If so, could you explain it to me using the previous question?

@SrMinister Fixed in v3.0.1. You must enable a transitiveInitialData option in your ViewFrame/View configuration

Enable it globally

viewFrame.defaultConfig(config -> config.transitiveInitialData(true));

Or per-view

config.transitiveInitialData(true);
