How populate navigation templates?


We want to use only 1 Top-Navigation screen, called DefaultTop.vm. 
Included in that template we have a PopUp selection list. 
Depending on the selected option we call different screens and
preselect it baseded on actual page. 
So we have to pass a parameter from jave- to template-level


We tried it the same way that works for screens properly:

Create a class with the same name and position (in the 
directory-hirarchie) and use the
context. 

The problem is Navigation.doBuild only has RunData. 
On the other hand VelocityNavigation.doBuild has 2 constructor, and also 
one that has 
the context.
But in reality turbuine/velocity seems only to use the simple one.
data.getPage().getBody().addElement works, but is not really what we 
wanted.
Additionally we get an error in the browser:
"Error processing navigation template:/DefaultTop.vm using module: 
DefaultTop"
We are not able to pass a parameter by context...

Has anyone an idea?



\webapps\test\templates\navigations\DefaultTop.vm
\webapps\edesk3\WEB-INF\src\java\org\youts\test\modules\navigations\DefaultTop.java

public class DefaultTop extends VelocityNavigation
{
    public ConcreteElement doBuild( RunData data, Context context)
        throws Exception
    {
        data.getPage().getBody().addElement("TEST RF1");
                  context.put("rf", "TEST RF1_B");
        return null;
    }
 
    public ConcreteElement doBuild( RunData data)
        throws Exception
    {
          data.getPage().getBody().addElement("TEST RF2");
                  context.put("rf", "TEST RF2_B");
        return null;
    }
}

TurbineResources.properties:
services.TurbineTemplateService.default.navigation=VelocityNavigation

Other question: What's the best way to pass parameters from one navigation 
template to another?

Yep, this is what works for me.

This should be
   "public void doBuildTemplate(RunData data, Context context)"

And why are you trying to add content to the page here? That's what the 
template is for...

In the context.
