Re: [julia-users] Got an exception of type ErrorException outside of a @test: type DataType has no field FactorMargin

If you can produce a minimal working example (the *shortest* piece of code that 
produces the problem and that people can run), you will be more likely to get 
help. This probably involves removing a lot of stuff from your code that I'd 
not relevant to this particular problem.
