JSF Design View broken? Fallback Rendering, "Render Kit" not found

Question

Hi,
I just wanted to toy around with JDeveloper 11g TP3, created a new project, added technology scope JSF (+ JSP/Servlets, etc.) then the tag-library ADF Faces Component 11-ji3.
Then I created a data control from a POJO and wanted to visualize this within a JSF page. So I created one (via faces-config visual editor), dragged the appropriate getter-method to the page in the up-to-this-point working WYSIWYG editor, selected ADF-read-only-form and suddenly found myself in the JSF "alternate rendering" (a view like in an hierachical XML editor). I enabled "design time messages in log" to see what the problem was.
Stopping/Starting JDeveloper or removing tag libraries like suggested in other threads did not work. I was unable to reactivate the wysiwyg editor for this page or any new JSF page in this application, always the "alternate rendering".
Log said "oracle.sql.OraData" was missing, so I added ojdbc6.jar to the project classpath. Didn't help, no wysiwyg editor, log now says:

I have this error even for newly created (ie blank/HelloWorld) JSF pages in my application. I started adding some libraries, but nothing helped. How do I reactivate the wysiwyg editor?
Thanks!

Frank,
thanks for the reply. I will try what you suggested, but the trinidad-config.xml is actually not missing in my project, although it does not include a render kit definition.
As my first step with 11g I also tried one of the tutorials (http://www.oracle.com/technology/obe/obe11jdev/11/ejb/ejb.html) and there the wysiwyg was working nicely the whole time.
In both cases (my project == not working wysiwyg editor, tutorial == nicely working wysiwyg editor) the content of the trinidad-config.xml is the same:
--- trinidad-config.xml ---
<?xml version="1.0" encoding="windows-1252"?>
<trinidad-config xmlns="http://myfaces.apache.org/trinidad/config">
<skin-family>blafplus-rich</skin-family>
</trinidad-config>
--- end-of-file ---
