Reusable parameters can't actually be reused

[rbdixon]

I've modified the reusableParameters.json example from the Swagger 2.0 spec. In the example the parameters limitParam and skipParam are not actually reused. I modified the example to use them again.

When I modified the example to use these parameters by simply duplicating the /pets path as /dup_pets I get the following failure:

java.lang.ClassCastException: com.wordnik.swagger.models.parameters.RefParameter cannot be cast to com.wordnik.swagger.models.parameters.BodyParameter
    at com.wordnik.swagger.codegen.DefaultCodegen.fromParameter(DefaultCodegen.java:796)

I'm confused since this seems to be the purpose of having parameters refs. Where am I going wrong?

I'm having the exact same problem. Best I can tell it's to the spec but the codegen is broken.

This is a bug. If you remove the first operation it works fine, I believe this is a problem in the parser project.
