How to extend rich:datatable with CDK

[zsv]

Hello. I want to extend rich:datatable with CDK (ver 4.3.1.Final)

I created maven project using cdk wiki and created 2 files: component and package-info.

Project compiled, but if I include my custom datatable in page nothing displayed. No errors, warning, just nothing.

How can I extend rich datatable with cdk?

AbstractDataTableExt.java

package ru.zpage.projects.richfaces.datatable.component;

import java.io.Serializable;

import javax.faces.component.UIComponent;

import org.richfaces.cdk.annotations.*;
import org.richfaces.component.AbstractDataTable;
import org.richfaces.component.UIDataTableBase;

@JsfComponent(
        type = "ru.zpage.projects.richfaces.datatable.DataTableExt", 
        family = AbstractDataTable.COMPONENT_FAMILY,
        renderer = @JsfRenderer(type = "org.richfaces.DataTableRenderer"), 
        tag = @Tag(name = "dataTable", 
        handler = "org.richfaces.taglib.DataTableHandler", 
        type = TagType.Facelets), attributes = {
        "style-prop.xml", "styleClass-prop.xml", "iteration-props.xml", "rows-prop.xml", "sequence-props.xml",
        "events-row-props.xml" })
public abstract class AbstractDataTableExt extends UIDataTableBase implements Serializable{

    public static final String CAPTION_FACET_NAME = "caption";
    

    @Attribute
    public abstract String getCaptionClass();
    
    @Attribute
    public abstract String getStyleClass();

    @Facet
    public abstract UIComponent getCaption();

}

package-info.java

@TagLibrary(uri="http://zpage.ru/richfaces",shortName="zpageLib")
package ru.zpage.projects.richfaces.datatable.component;
import org.richfaces.cdk.annotations.TagLibrary;

Hey Sergey,

when I need to extend rich:dataTable component including renderer logic, I would use copy and rename all the relevant sources:

• JSF component sources
  • component (AbstractDataTable) -> AbstractDataTableExt
  • renderer (DataTableRenderer) -> DataTableExtRenderer
  • optionally tag handler (DataTableHandler)
• associated resources
  • datatable.css
  • datatable.js

Just remember to rewrite all the associated names - type, family, renderer-type.

A good approach is to always check whether everything is fine in generated faces-config.xml and *.taglib.xml.

Here is a sample of dataTable extension projects with demo:
