OK, it's not so puzzling; sorry.  The cell

   Manipulate[ Plot[ x^a, {x,0,1} ], {a, {0,1}, 5 } ]

creates a Slider2D, and plots two independent curves, with no error 
indications.

Not sure if this syntax is documented anywhere in the Manipulate or 
Slider2D documentation, or is intended to be valid, but it appears to 
work.
