    Hi, I need to show on the result table a column with a nested field,
    I have a foreign key object on my entity and I want to show on the table the id field of that object,
    is it possible?
    Thank you

    Yes it's possible but the way to do it depends on what object you are rendering as a table.

    In Roma if you render a Collection as a table every field that has a getter will be rendered so you just need to add a getter in your object. All object return values will be rendered as string using the toString().

    List<MyObject> table;

    public class MyObject{
        public String getFirstString(){
             return "test1";
        public String getFK(){
             return fkString;
    // OR
    public Object getFK(){
             // If not loaded code to load your object
             return fk;

    Ok, so when I need to show a nested field I will implement the getter and setter methods,
    thank you.
