I'm using overloaded functions:

void ViewHistory()
{
  some code
}

void ViewHistory(String conditions)
{
  some other code
}

I'm calling this function by using THISBACK like this:

bar.Add("Aufwahlhistorie", ImgMainWnd::history(), THISBACK(ViewHistory)).Key(K_ALT_A).Help("Aufwahlhistorie").Enable(true);

Before i used overloading all went fine, since i'm using this overloaded function i got the following compile-error:

K:\Entwicklung\UPP\prohibisZA\prohibisZA.cpp(734) : error C2668: 'Upp::callback' : ambiguous call to overloaded function
        c:\upp\uppsrc\core\Cbgen.h(229): could be 'Upp::Callback1<P1> Upp::callback<prohibisZA,prohibisZA,Upp::String>(OBJECT *,void (__th
	iscall prohibisZA::* )(P1))'
        with
        [
            P1=Upp::String,
            OBJECT=prohibisZA
        ]
        c:\upp\uppsrc\core\Cbgen.h(80): or       'Upp::Callback Upp::callback<prohibisZA,prohibisZA>(OBJECT *,void (__thiscall prohibisZA:
	:* )(void))'
        with
        [
            OBJECT=prohibisZA
        ]
        while trying to match the argument list '(prohibisZA *const , overloaded-function)'

How do i use THISBACK when using function-overloading?
