NB6 NBI build200706141200:
Follow the tutorial http://bookshelf.sfbay/jets/Rave/Tutorials/tutorials/shortfin/kb/55/vwp-ajaxrating.html
Run the application.
Go back the ide,  and then switch back to designer. the following NPE is shown in design. The java file can be compiled
without error though:

Comment 1 Matthew Bohm 2007-06-25 23:18:48 UTC 
This is a classloading issue. There should be some designtime debugging output emitted just before the stack trace in
the IDE log. The insync team will likely have to look at this debugging information. The only curious thing is that I've
used the rating component (version 0.1.2) sucessfully in nb6 before, so I wonder why you are seeing this.
Comment 2 _ hlu 2007-06-26 00:03:05 UTC 
I also used complib 0.1.2.
Comment 3 Matthew Bohm 2007-07-02 22:53:08 UTC 
I believe this error has always been there. It is insync related, and, to my knowledge, not specific to the blueprints
complib.

It is not a very serious error, because simply clicking OK to the red designer screen makes everything all better.
Therefore downgrading to P3. Reassigning to the insync team.

I was able to reproduce this by first deploying and then doing a "clean and build" and then clicking the rating
component in the outline and modifying a property in the property sheet (such as the includeClear property).

Here is my log output, giving the classloader debugging information:

RatingRenderer.encodeBegin: expected type class com.sun.j2ee.blueprints.ui.rating.RatingComponent but found class
com.sun.j2ee.blueprints.ui.rating.RatingComponent
