Add definition refactoring bug

For example, I have class

class SerializableClass
{
  public:
	SerializableClass(const Poco::Data::RecordSet& recordSet);
	//// Serializing
	void Save(rapidjson::Value& json, rapidjson::Document::AllocatorType& allocator) const;

  private:
	...
};

Then I left click on Save function -> Refactor ->  Add Definition in source file

QtCreator creates definition in my source file but with wrong signature

void SerializableClass::Save(rapidjson::Value &json, rapidjson::GenericDocument::AllocatorType &allocator) const
{
	
}

As you can see rapidjson::Document::AllocatorType becomes rapidjson::GenericDocument::AllocatorType

Document -> GenericDocument and it's not the same types

They have typedef

typedef GenericDocument<UTF8<> > Document;

So looks like QtC ignores explicit template instantiation and works with GenericDocument as non template class.
