Setting maxLength when using Sencha GXT

I am using Sencha GXT 3.1.1 to use it with GWT. Now I should limit the size of TextFields by using the maxLength attribute of HTML.

First of all, I haven't found any possibility to do that directly in this class, with setMaxLength() method.

Can anybody help how to use the maxlength attribute inside Sencha GXT classes?

You can also do the following:

InputElement inputElement = textField.getElement()
        .select("input")
        .getItem(0)
        .cast();
inputElement.setMaxLength(valueMaxLength);

There is a way, but it's a bit of a hack:

textField.getCell()
    .getAppearance()
    .getInputElement(textField.getElement())
    .setAttribute("maxLength", "3");

I think the best way to solve this problem is using a validator.

myTextField.addValidator(new MaxLengthValidator(3));

This validator will check if the value of the TextField has more than three letters. If it has more than three letters it will show an error.
