I´m a begginer in Primefaces.... And I tried to make the example DragDrop - Native Primefaces
I´ll posted all the clases and xhtml files involved for this example.
I can drag any columns but it´s not working the droping property....
You can see an image showing the trouble in this link https://lh3.googleusercontent.com/clMOtntqI99ltjXGYpzUGt-8yg4N8ahtQQIBT5leNA=w314-h207-p-no
The fist file is dndColumns.xhtml

And the third and last file is Car.java
package org.sagarpa.src.bean;
// import java.util.Date;
public class Car {
private String model;
private int year;
private String manufacturer;
private String color;
public Car(String model, int year, String manufacturer, String color) {
this.model = model;
this.year = year;
this.manufacturer = manufacturer;
this.color = color;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
public int getYear() {
return year;
}
public void setYear(int year) {
this.year = year;
}
public String getManufacturer() {
return manufacturer;
}
public void setManufacturer(String manufacturer) {
this.manufacturer = manufacturer;
}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
}
The problem exists when I want to drag any component because its can´t drop on the table or on the Columns area rectangle.
Please.... Could you help me to complete the code ??? Any sugestion ???
