Howto create a commandLink and param-attribute in a self written renderer?

Question

Hi guys,
I'm currently trying to write a JSF-component for a content-mangement-system.
The goal of the component is to render a HTML-page which lists all elements
of an article (with all things like text-components, pictures, headline etc.)
and provides a link for every article-element which referes the user to a
special JSF-site in which the selected article-component can be edited. For
example: the user sees the site which lists all article-elements and selects
a "edit this text-component button" from one text component. Aftter that he
would be forwarded to a "editTextComponent.jsf"-Site which loads the selected
component into a managed bean. The site "editTextComponent.jsf"-Site itself
would then provide a JSF-form which fields are binded with the managed-bean
properties. To do this I need my own component-renderer to create a special
"command link" with an additional parameter of the selected component ID
(similar to the <h:commandLink />- and <h:f:param />-Tags in a normal
JSF-site). Because I need the ID of the selcted component in the new
JSF-site.
Now I need to know how I can pass such a parameter in a renderer. In a
jsf-site I would simply do something like
<h:commandLink action="myUser.accessRequestEditTextComponent">
<h:outputText value="articleAdminPage.editThisTextComp" />
<h:f:param name="componentID" value="myTextComp.databaseID" />
</h:commandLink>
But how can I do such a thing in a JavaClass??? I already tried a thing like
public void encodeEnd(FacesContext ctx, UIComponent comp)
writer.write(" <form
action=\"../articlecomponents/createnewpiccomp.jsf\" method=\"get\">");
writer.write(" <input type=\"hidden\" name=\"position\" value=\"" +
textComponent.getID() + "\" />");
writer.write(" <input type=\"image\" src=\"" +
myUIArticle.getCreateNewIcon() + " \" />");
writer.write(" </form>");
But this is not working and it is very ugly because the url of the new site is
hard-coded (and not a "action"-attribute which can be used in the
faces-config.xml for navigation), I'm not able to pick out this attribute in
the new jsf-site and the HTML-code is also hard coded.
Can you guys give at least a little hint, a keyword to what I shall look for?
I have defintly no idea and I'm already a little bit despaired.
Greetings,
Hendrik

Okay, Martin from the myfaces-development-team has just anwsered my question. For all of you who have the same question: such a think that I'm trying to do is done in the "writeLink"-method in the HTMLCalenderRenderer-class of the myfaces-extensions. So take a look at this for an excelent example!
