I added the Columns then clicked on "Generate Services". It generated all the classes and I could see the newly
generated source code in the folders although the Columns went blank and when I clicked "Add" in "Columns" section again
nothing happened. The Design does not match the XML. I've attempted to make a new project then deleted them all and
reinstalled several times and I still get the same result. None of the UI buttons Add, Updatem or Remove work at all.
I running this on a mac, any ideas? 

Here is some items of possible importance from the log file:
SEVERE [org.netbeans.modules.mercurial]: execEnv():  execEnv(): IOException java.io.IOException: hg: not found

This one is not suprising, although may help in debugging: 
When I click over to the "Finders" tab (with no Columns (because I can't add any) and click remove I get this:
SEVERE [global]
java.lang.NullPointerException
