 * Old Input type.
 * The reason I still keep Old Input is for compatibility. There's one bug in the old input forms.
 * There's 2 ways to create input forms: frontend & backend.
 * The bug is in frontend. The type would not be set correctly when input form
 * is created in frontend (Input.getInputForm).
