Description

When I have a model with a property that is a List of Dictionary<x,y> the generated code is public List<Dictionary> MyProperty {get; set;} instead of public List<Dictionary<x,y>> MyProperty {get;set;} causing compilation issues (Using the generic type 'Dictionary<TKey, TValue>' requires 2 type arguments) . I have debugged the model and I noticed that model.vars.dataType is incorrect but model.vars.items.dataType is correct:

It seems that model.vars.items.dataType looks fine so I'd suggest porting the same logic to model.vars.dataType
