DataTable and Filter

Alexandre · 17 Mar 2011, 16:58

Hi, i m testing primefaces for Energie Company in FRANCE. I have probleme with datatable in lazy mode.

What steps will reproduce the problem?
On complex datatable exemple
1.Select a row.
2.Use a Filter
3.Select an other row.

What is the PrimeFaces version?
I test it with 2.2.1, 2.2.1-SNAPSHOT 2011-03-17, and primefaces 3.0.

What is the expected output? What do you see instead?
I see the first information of step 1 row.

Which JSF implementation with version are you using?(Mojarra or MyFaces)
Mojarra 2.1.1.B02

Which component libraries are you using in addition to PrimeFaces?
none

Which application server or servlet container are you using?
Tomcat 6

The code

car.java

Code: Select all

package org.primefaces.examples.view;

public class Car {

	private String model;
	private Integer year;
	private String manufacturer;
	private String color;

	public Car(String randomModel, Integer randomYear,
			String randomManufacturer, String randomColor) {
		this.model=randomModel;
		this.year=randomYear;
		this.manufacturer=randomManufacturer;
		this.color=randomColor;
	}

	public String getModel() {
		return model;
	}

	public void setModel(String model) {
		this.model = model;
	}

	public Integer getYear() {
		return year;
	}

	public void setYear(Integer 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;
	}
