Hi,

Was wondering if this is currently possible as I’m currently getting:

System.ArgumentException : wrong number or type of arguments for  
`Render' at _stub_$19##19(Closure , CallSite , RubyMethodScope , Object , Proc , Object ) C:\Dev\ironruby\trunk\src\Microsoft.Scripting.Core\Actions\MatchCaller.Generated.cs(40,0): at System.Scripting.Actions.MatchCaller.Call4[T0,T1,T2,T3,TRet](Func`6  
target, CallSite site, Object[] args)  
C:\Dev\ironruby\trunk\src\Microsoft.Scripting.Core\Actions\CallSite.cs(275,0):  
at System.Scripting.Actions.CallSite`1.UpdateAndExecute(Object[] args)  
C:\Dev\ironruby\trunk\src\Microsoft.Scripting.Core\Actions\UpdateDelegates.Generated.cs(52,0):  
at  
System.Scripting.Actions.UpdateDelegates.Update4[T,T0,T1,T2,T3,TRet](CallSite  
site, T0 arg0, T1 arg1, T2 arg2, T3 arg3)

// c#

public abstract class ViewBase {  
public virtual void Render(TextWriter textWriter)  
{  
}  
}

// rb

class MyView \< ViewBase  
def Render(text\_writer)  
super  
end  
end

Cheers,

Andrew.

I’m fairly sure this was working at some point – my bad for not adding  
an appropriate test :(.

I’ll try to get the barebones structure in tomorrow so we can get tests  
in.
