How to show a panel or any other GUI object in OpenFaces 3.00 Datatable upon row selection?
I am using OpenFaces 3.0.0 with JSF 2.0, Fadelets, Managed Beans and Tomcat server. I have a openface datatable and now on the basis of row selection, I want to show some different data (other than the data displayed in the datatable) in a folding panel or any other suitable openfaces layout. I have tag called singleRowSelection in the openfaces table. Could you please let me know to configure openfaces datat开发者_StackOverflow中文版able so that on row selection I can show data on a panel below the datatable? I need to show/hide data based on row selection Please help
I'd take a look at o:singleRowSelection http://openfaces.org/documentation/tagReference/o/singleRowSelection.html
Here is a super basic example:
<!DOCTYPE html>
<h:head>
<title>Example Row Change DataTable</title>
</h:head>
<h:body>
<h:form prependId="false" id="sampleForm">
<o:dataTable id="sampleDataTable" value="#{testOpenFacesBean.testStrings}" var="name">
<o:singleRowSelection render="somePanel" action="#{testOpenFacesBean.randomize}"/>
<o:column>
<h:outputText value="#{name}" />
</o:column>
</o:dataTable>
</h:form>
<h:panelGroup layout="block" id="somePanel">
<h:outputText value="#{testOpenFacesBean.randomName}" />
</h:panelGroup>
</h:body>
package com.test;
import java.math.BigInteger;
import java.security.SecureRandom;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
@ManagedBean(name = "testOpenFacesBean")
@RequestScoped
public class TestOpenfacesBean {
/**
* A collection of Strings for testing Openfaces singleRowSelection
*/
private List<String> testStrings;
public List<String> getTestStrings() { return this.testStrings; }
public void setTestStrings(List<String> testStrings) { this.testStrings = testStrings; }
/**
* A random name so you can see the data updating
*/
private String randomString;
public String getRandomName() { return this.randomString; }
public void setRandomName(String randomName) { this.randomString = randomName; }
/**
* Constructor
*/
public TestOpenfacesBean() {
this.testStrings = new ArrayList<String>();
this.testStrings.add("Beth");
this.testStrings.add("Jane");
this.testStrings.add("Doug");
}
public void randomize() {
this.randomString = new BigInteger(62, new SecureRandom()).toString();
}
}
