Title: RE: writing is own HtmlDataTable

I had to make a custom extension of HtmlDataTable for a recent project.  To do that I extended MyFaces HtmlDataTable:

//...
import org.apache.myfaces.component.html.ext.HtmlDataTable;
import org.apache.myfaces.component.UserRoleAware;
// ...
public class CustomPaginationHtmlDataTable extends HtmlDataTable implements
                UserRoleAware {
//...
}

I also created a tag for my custom table:

import org.apache.myfaces.taglib.html.ext.HtmlDataTableTag;

public class CustomPaginationHtmlDataTableTag extends HtmlDataTableTag {
    public String getComponentType()
    {
        return CustomPaginationHtmlDataTable.COMPONENT_TYPE;
    }
   
    public String getRendererType()
    {
        return "org.apache.myfaces.Table";
    }
}

I then added the custom table to an appropriate faces-config.xml:

<faces-config>
  <component>
    <component-type>com.dbz.lms.faces.CustomPaginationHtmlDataTable</component-type>
    <component-class>com.dbz.lms.faces.component.CustomPaginationHtmlDataTable</component-class>
  </component>
<!-- more components -->
</faces-config>

and added the custom tag to an appropriate taglib file:

    <tag>
        <name>customPaginationDataTable</name>
        <tagclass>com.dbz.lms.faces.taglib.CustomPaginationHtmlDataTableTag</tagclass>
        <bodycontent>JSP</bodycontent>
        <attribute>
            <name>id</name>
            <required>false</required>
            <rtexprvalue>false</rtexprvalue>
        </attribute>
<!-- more attribute declarations... -->
  </tag>

At that point, the tag is available for use beneath whatever namespace you have defined for your custom tag library.  I'm sure there's more information on the wiki:  http://wiki.apache.org/myfaces/

Hope that helps,

James
