Clear button triggers a controller call with empty text

[François]

I set MinLength on Autocomplete.

However when I click on the "clear" icon of the autocmplete box there are a few unexpected behaviors

- there is a call to the controller with empty text

- the dropdown remains open saying "no data found"

Hello François,

In our demos when the input is cleared a request is sent to the server and it returns all the items. The No data found message is not displayed:
Here's the Action that is called:

public JsonResult GetProducts(string text)
{
    var northwind = new SampleEntities();


    var products = northwind.Products.Select(product => new ProductViewModel
    {
        ProductID = product.ProductID,
        ProductName = product.ProductName,
        UnitPrice = product.UnitPrice ?? 0,
        UnitsInStock = product.UnitsInStock ?? 0,
        UnitsOnOrder = product.UnitsOnOrder ?? 0,
        Discontinued = product.Discontinued
    });

    if (!string.IsNullOrEmpty(text))
    {
        products = products.Where(p => p.ProductName.Contains(text));
    }

    return Json(products, JsonRequestBehavior.AllowGet);
}

Could you share your AutoComplete declaration? This would give us a better idea of how it is configured.
