Why is enum not allowed with Simulink.Parameter in R2014b.

Hi,

I have been trying to generated code using embedded coder for a small model.

One of the parameters is an enum to be imported from an external file. I created an enum class as imported.

When I am trying to use this enum as a data type in Simulink.Parameter it returns an error that Simulink Parameter cannot be converted to enum data type.

Could you tell any alternate method if possible.
