viList in JS has undefined fields in handler

[DushkaF]

Describe the bug.

I’m trying to use vi_list in a JS app on Flipper Zero, but the valueUpdate event does not provide usable data.

According to documentation, the event should return fields like:

• item_index
• value_index

However, in practice both fields are undefined.

Reproduction

let eventLoop = require("event_loop");
let gui = require("gui");
let viListView = require("gui/vi_list");

let views = {
    config: viListView.makeWith({}, [
        { label: "Port", variants: ["usart", "lpuart"] },
        { label: "Baud", variants: ["57600", "115200", "921600"] },
    ]),
};

eventLoop.subscribe(views.config.valueUpdate, function (_sub, item) {
    // Trying to inspect event payload
    print("item_index:", item.item_index);
    print("value_index:", item.value_index);
});

eventLoop.subscribe(gui.viewDispatcher.navigation, function (_sub, _item, gui, views, eventLoop) {
    if(gui.viewDispatcher.currentView === views.config) {
        eventLoop.stop();
        return;
    }

    gui.viewDispatcher.switchTo(views.config);
}, gui, views, eventLoop);

gui.viewDispatcher.switchTo(views.config);
eventLoop.run();
