The idea is not to publish the Node into the Lookup. The idea is that 
when the user selects the Node, the Object that the Node visualizes is 
published into the Lookup. That is done in the constructor of the Node.

Many tutorials on Node here: https://netbeans.org/kb/trails/platform.html

Also, please read the chapter on this topic hereL leanpub.com/nbp4beginners
