USAGE method not displaying possible Object values for List of Objects

[mjandersonjr]

I'm using JCommander 1.72. 

--------------------

import com.beust.jcommander.JCommander;
import com.beust.jcommander.Parameter;

import java.util.ArrayList;
import java.util.List;

public class Main2 {

    public enum ChoiceType { ONE, TWO, THREE };
    @Parameter(names = "-choice")
    public ChoiceType choice = ChoiceType.ONE;

    @Parameter(names = "-choices", variableArity = true)
    public List<ChoiceType> choices = new ArrayList<ChoiceType>();

    public static void main(String[] args1) {
        Main2 args = new Main2();
        String[] argv = { "-choice", "ONE"};
        JCommander jc = new JCommander(args, argv);
        jc.usage();
    }
}

-------------

output:

-------------

Usage: <main class> [options]
  Options:
    -choice
      Options: [ONE, Two, THREE]
      Default: ONE
      Possible Values: [ONE, Two, THREE]
    -choices

      Default: []

------------------------

Is there an option I can set to make the possible values display for the "choices" variable, like it does for the "choice" variable?

No. It would have to be very specific code too (i.e. "container of an enum type"), so I'm not sure it's worth the trouble...
