/**
 * TO BE FIXED:
 *
 * 1.- when the form change to other form and both form share the same structure
 * the same input component may be rendered in the same place,
 * since input are uncontrolled the are not re-rendered and since they are
 * uncontrolled it will keep the value of the previous form.
 * One solutions could be to remove the form when unloading and when the new
 * form load it will start without previous vdom, preventing the cache
 * to create this behavior.
 * Other solutions could be using IDs in the fields that are constructed
 * with the ID of the form, so two fields of different form will need to re-render
 * cleaning up the state of the previous form.
 *
 * 2.- currently the design prop and the behavior prop of the flexible form
 * are two side of the same coin. From the design point of view, it is important
 * to design the form in a list-of-field manner and there may be additional
 * content that is not directly mapped to the form structure (object)
 * So maybe we want to change the current shape so the computation of the state
 * of the form is in a field level, but this computation required the field value and
 * the whole form values and state (since one field may be disabled/hidden) because
 * of the value of other field.
 *
 * 3.- given the previous requirement, maybe the name of the field of the form could be
 * a function (P: F -> V) where F is the form (or parent object) and V is the type of the
 * property. That will help with the typing of the forms props
 *
 * 4.- tooltip are not placed correctly: the arrow should point the question mark
 * and the text area should be bigger
 *
