Request request generated for EntitySet is invalid

Question

I get this error, I tried Restore Views from EF Power Tools and no luck! What might cause this exception:

'System.Data.Entity.Core.EntityCommandCompilationException' occurred in mscorlib.dll but was not processed in user code. An error occurred while preparing a team definition. See Internal Exception for more details. {"The query representation generated for EntitySet 'generators is not valid. The query parser generated the following error: Argument type" Edm.Single "is incompatible with the Price property of the formal type" Edm.String ". Member access expression, row 3, column 155 .. "}

thank!
