I have made a template singleton class, I have also made a data structure that is templated.

My question is; how do I make my templated data structure inherit from a singleton so you can only have one float type of this structure?

I have tested both seperate and have found no problems. Code provided under... (That is the problem)

template <class Type>
class AbstractRManagers : public Singleton<AbstractRManagers<Type> >

The problem is the code above doesn't work I get alot of errors. I cant get it to no matter what I do template a templated singleton class... I was asking for maybe advice or maybe if the code above is incorrect guidence?
