Dynamically add Children Link Element

Question

Hi,
I'm trying to dynamically add a children element, a link, but the action binding refuses to work ...
I've created a custom jsf component, that does nothing at all.
For example, one would use it like:
<my:nothing></my:nothing>So my UI class would have the following methods:
public void encodeBegin(FacesContext context) throws IOException {
public void encodeEnd(FacesContext context) throws IOException {
}The tld file is created, the tag class is working. All the component is working properly.
Now I want to add a link as a child component, but I wat to do it programatically, so I changed the encodeBegin method of my custom ui class:
import javax.faces.el.ValueBinding;
import com.sun.faces.util.Util;
import javax.faces.el.MethodBinding;
import javax.faces.component.UICommand;
import javax.faces.component.html.HtmlCommandLink;
import com.sun.faces.taglib.html_basic.CommandLinkTag;
public void encodeBegin(FacesContext context) throws IOException {
          String myLinkId = "idMyLink";
          String myLinkValue = "myLink:Value";
          String myLinkStyle = "color:green;";
          String myLinkAction = "backup";
          HtmlCommandLink myLink = new HtmlCommandLink();
          myLink.setParent(this);
          myLink.setId( myLinkId );
          if (CommandLinkTag.isValueReference( myLinkValue )) {
               ValueBinding vb = Util.getValueBinding( myLinkValue );
               myLink.setValueBinding("value", vb);
          } else {
               myLink.setValue( myLinkValue );
          if (CommandLinkTag.isValueReference( myLinkStyle )) {
               ValueBinding vb = Util.getValueBinding( myLinkStyle );
               myLink.setValueBinding("style", vb);
          } else {
               myLink.setStyle( myLinkStyle );
          if(myLinkAction!=null) {
               if (CommandLinkTag.isValueReference( myLinkAction )) {
                    System.err.println("Id="+myLinkId+":TRUE:getAccao:isValueReference:"+myLinkAction);
                    MethodBinding vb = getFacesContext().getApplication().createMethodBinding(myLinkAction, null);
                    myLink.setAction(vb);
               } else {
                    System.err.println("Id="+myLinkId+":FALSE:getAccao:isValueReference:"+myLinkAction);
                    final String outcome = cNfo.getAccao();
                    MethodBinding vb = Util.createConstantMethodBinding( myLinkAction );
                    myLink.setAction(vb);
          myLink.encodeBegin(getFacesContext());
          myLink.encodeEnd(getFacesContext());
}This seems to work, but not quite ... the link appears as expected, the value references for value and style are correctly passed, but the action doesn't work at all.
For example if I change to:
String myLinkValue = "#{mybean.linkText}";And I have the following method created on my managed bean:
     public String getLinkText() {
          return "This is myLink Text!";
     }Is successfully calls and retrieves the value from the method. Same happens to the style property.
Now for the action, if I change to:
String myLinkAction = "#{mybean.doMyLinkAction}";And I have the following method created on my managed bean:
     public String doMyLinkAction() {
          return "backup";
     }The result is nothing ... I mean the method is not called at all. The "backup" is properly defined on my "faces-config.xml":
   <navigation-rule>
      <from-view-id>/testPage.jsp</from-view-id>
      <navigation-case>
         <from-outcome>yes</from-outcome>
         <to-view-id>/yes.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>no</from-outcome>
         <to-view-id>/no.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>backup</from-outcome>
         <to-view-id>/backup.jsp</to-view-id>
      </navigation-case>
   </navigation-rule>If I create the link manually on the web page:
<h:commandLink id="myLinkManual" value="Manually Created Link" style="" action="#{mybean.doMyLinkAction}"/>It does work (the backup.jsp page is shown), so the methods are properly configured, only the action binding does not work.
Wether I use a string "backup" or a reference "#{mybean.doMyLinkAction}" I cannot make it work.
On the console I get the following results, for each value I test (string "backup" or reference "#{mybean.doMyLinkAction}"):
Id=idMyLink:TRUE:getAccao:isValueReference:backup
Id=idMyLink:FALSE:getAccao:isValueReference:#{mybean.doMyLinkAction}So the "if (CommandLinkTag.isValueReference( myLinkAction )) {" is working properly ... that just leaves me with the action method binding instructions ...
Why don't they work?
Any Help Appreciated ... Thanks in Advance!
