what happened to 'dividenull" in the neural network toolbox?

I have codes running under matlab2010a that won't run under 2011b. I didn't want any validation in training and had set

net.divideFcn = 'dividenull';  % setting to null uses no validation or test set during training

now I get

Error using network/subsasgn>network_subsasgn (line 536)
"divideFcn" cannot be set to non-existing function "dividenull".

I did a search on "dividenull" in MATLAB Central and come up empty. How do I force no validation?

Hope this helps
