visual build add datasource to dynamicForm

Hello,
first off all
SC Version: v9.1p_2014-09-19/Pro
Browser:Firefox 31.0
Problem
after adding a dynamicForm I try to add a DataSource (i.e animals) and I Receive the error:TypeError: _1[i].hasAdvancedCriteria is not a function
I tried with different DataSource with the same result.
I don't have a demo in the moment but i Believe that you can try out quick.

Kind regards

Paul
