[news.eclipse.webtools] Create tag transform operation in jsf tools

[ronaldo.ramos.silva@xxxxxxxxx (Ronaldo )]

Hi for all.
Sorry for my english.
I'm using extension point pageDesignExtension to create a new 
TransformOperation for my tags. But don't work, I create the class 
extending AbstractTransformOperation and create in my DTI file the 
reference for this operation, and make the inclusion of extesion point in 
plugin.xml but don?t work. IŽm forgot something?
Above the source code. 
please help me.

Class
package com.mytag.test;

import org.eclipse.core.runtime.Assert;
import 
org.eclipse.jst.pagedesigner.dtmanager.converter.operations.AbstractTransformOperation;
import org.w3c.dom.Element;

/**
* ITransformOperation implementation that creates a new Element.
* 
* <br><b>Note:</b> requires 
ITransformOperation.setTagConverterContext(...) to
* have been called to provide a valid ITagConverterContext instance prior 
to
* a call to the transform(...) method.

public class CreateElementOperation extends AbstractAWBTransformOperation {

	private String tagName;
	private String x;
	/*

org.eclipse.jst.pagedesigner.dtmanager.converter.operations.internal.provisional.AbstractTransformOperation#transform(org.w3c.dom.Element,

	 */
	public Element transform(Element srcElement, Element curElement) {
		
		if (getParameters().length < 1) {
			//getLog().error("Warning.TransformOperationFactory.TooFewParameters", 
getTransformOperationID()); //$NON-NLS-1$
			return null;
		} 
		
		tagName = getParameters()[0];
		Assert.isNotNull(tagName);
		
		Element element = null;
		if (tagConverterContext != null && tagName != null && tagName.length() > 
0) {
			element = tagConverterContext.createElement(tagName);
		}
		return element;
	}
