In the docs about model driven https://struts.apache.org/core-developers/model-driven.html <https://struts.apache.org/core-developers/model-driven.html>
It is said that you must to implement the MovelDriven interface just the method getModel() to give an Object in which Struts populate with the parameters request and placed on the top. i din’t understand the need of that because i can populate the object if it is a field of the Action’s class. So what is the difference (the use of OGNL?) i can’t accede object properties? My object person is of type Person class and it is a field of the action Register. Why can’t access to levels property of the object person by person.levels??
