Hi,

When I'm trying to pass a vector to a callback routine:

GUI_APP_MAIN
{
	Callback1< Vector<int> > SomeCallback;
	Vector<int> v;
	SomeCallback(v);
}

GCC in c++11 mode gives me error: "use of deleted function":

/home/zbych/upp/uppsrc/Core/Cbgen.h:122:7: error:   initializing argument 1 of void Upp::Callback1<P1>::operator()(P1) const [with P1 = Upp::Vector<Upp::String>]
  void operator()(P1 p1) const   { Execute(p1); }
       ^

  virtual void Execute(P1 p1) = 0;

What am I doing wrong? I don't want to pass a reference or pointer to Vector instead of Vector itself, since it is local object and I want to use PostCallback to pass it to GUI thread.
