Description

HTML4J does not correctly support Knockout's "checked" binding that includes checkedValue. The following code snippet illustrating the use case is copied from the Knockout documentation:

<!-- ko foreach: items -->
    <input type="checkbox" data-bind="checkedValue: $data, checked: $root.chosenItems" />
    <span data-bind="text: itemName"></span>
<!-- /ko -->

<script type="text/javascript">
    var viewModel = {
        items: ko.observableArray([
            { itemName: 'Choice 1' },
            { itemName: 'Choice 2' }
        ]),
        chosenItems: ko.observableArray()
    };
</script>

Having the corresponding Java:

@HTMLDialog(url = "<snippet>.html")
static HTMLDialog.OnSubmit showUI() {
    ViewModel model = new ViewModel();
    model.applyBindings();
    return (id) -> {
        List<Item> chosenItems = model.getChosenItems();
        return !chosenItems.isEmpty();
    };
}

@Model(className = "ViewModel", targetId = "", instance = true, builder = "with", properties = {
    @Property(name = "chosenItems", type = Item.class, array = true)
})
static final class ViewModelControl {
    @ComputedProperty
    static List<Item> items() {
        return Arrays.asList(new Item("Choice 1"), new Item("Choice 2"));
    }
}

@Model(className = "Item", instance = true, properties = {
    @Property(name = "itemName", type = String.class)
})
static final class ItemControl {
}

The content of `chosenItems` does not reflect changes in checkbox selection.
