Datatable problem

pfrules · 18 Sep 2011, 23:48

Hi everyone,

I am new to JSF and primefacs.

I am trying to implement a datatable similar to the primefaces showcase example here.. http://www.primefaces.org/showcase/ui/d ... Column.jsf

I need a working version that works similar to the one above and also has a delete and update functionality.

Any help will be greatly appreciated. The link example above does not work.complains about (import org.primefaces.examples.domain.Car;) is not found and and once I get just Car class I get "no records found"

I have eclipse , tomcat 6, primefaces 3.0.M3/2.2.1

The example code above with Car class is...

I got part of my issue resolved. I totally forgot the following in TableBean.java

@ManagedBean
@SessionScoped

That got the first example to work.

Now I have weird problem,

If you try veiw a record and you click the image on the right, it pulls up the wrong record.

Any idea as to why??

Thanks in advance.

Again,

I fixed my issue by removing the example Random methods from TableBean and change the class to... This works....
==============
TableBean.java
-----------------

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import javax.enterprise.context.SessionScoped;
import javax.faces.bean.ManagedBean;

@ManagedBean
@SessionScoped
public class TableBean implements Serializable {
/**
*
*/
private static final long serialVersionUID = -6354969164694344839L;

private final static String[] colors;

private final static String[] manufacturers;

private List<Car> cars;

private Car selectedCar;

static {
colors = new String[10];
colors[0] = "Black";
colors[1] = "White";
colors[2] = "Green";
colors[3] = "Red";
colors[4] = "Blue";
colors[5] = "Orange";
colors[6] = "Silver";
colors[7] = "Yellow";
colors[8] = "Brown";
colors[9] = "Maroon";

manufacturers = new String[10];
manufacturers[0] = "Mercedes";
manufacturers[1] = "BMW";
manufacturers[2] = "Volvo";
manufacturers[3] = "Audi";
manufacturers[4] = "Renault";
manufacturers[5] = "Opel";
manufacturers[6] = "Volkswagen";
manufacturers[7] = "Chrysler";
manufacturers[8] = "Ferrari";
manufacturers[9] = "Ford";
}

public TableBean() {
cars = new ArrayList<Car>();

populateCars(cars, 5);
}

private void populateCars(List<Car> list, int size) {

list.add(new Car("111111",1999,"Tayota","White"));
list.add(new Car("222222",2000,"Ferari","Red"));
list.add(new Car("333333",2001,"Fiat","Blue"));
list.add(new Car("444444",2002,"Pontiac","Green"));
list.add(new Car("555555",1999,"Honda","Yellow"));
}

public Car getSelectedCar() {
return selectedCar;
}

public void setSelectedCar(Car selectedCar) {
this.selectedCar = selectedCar;
}

public List<Car> getCars() {
return cars;
}

}
