    I figured out the problem with the Category Delete.....it wasn't wired up in the object datasource.  I just had to go in and select the delete method.

    I found a work around for the Delte Project button.  It didn't work on the project list page grid but it did work on the edit page so I just removed the delete button from the grid.  Then i just deleted using the delete button at the bottom of the edit page
