Error on Entity Listener

Hi i’ve Created a Entity Listener:


package com.company.imgestion.listener;

import org.ocpsoft.prettytime.shade.net.fortuna.ical4j.model.Date;
import org.springframework.stereotype.Component;
import com.haulmont.cuba.core.listener.BeforeUpdateEntityListener;
import com.company.imgestion.entity.Articulos;

@Component("imgestion_BajaArticulos")
public class BajaArticulos implements BeforeUpdateEntityListener<Articulos> {


    @Override
    public void onBeforeUpdate(Articulos entity) {
        if (entity.getBaja()){
            entity.setFechabaja(new Date());
        }
    }


}

but when i set Baja to True i get the following error:

The error has nothing to do with the entity listener.
The problem is that you are trying to store an unsupported type in the entity attribute. For the list of supported types, see https://doc.cuba-platform.com/manual-6.2/data_model.html. I would recommend using standard types in entities and make conversions from non-standard types, if needed, outside of the entities.

Thanks Konstantin!

WHen i Use auto import of References from IntelliJ Idea, we’ve imported:

import org.ocpsoft.prettytime.shade.net.fortuna.ical4j.model.Date;

and the good is

import java.util.Date;

Thanks for your help! This solved the Issue!
