Problem with parameters when calling bound function from js

[ray007]

There seems to be a problem with managing missing/optional parameters.
in JavascriptObjectRepository.cs line 123 my null-Parameter from javascript gets matched in replaced by a MissingParameter.

i.e. C#:

public void setData(string data1, string data2 = null) { ... }

The failing call in javascript looks like this:

window.cef.setData(null);

Resulting Exception:

System.InvalidOperationException occurred
  HResult=-2146233079
  Message=Could not execute method: showLWebPage(System.Reflection.Missing, System.Reflection.Missing) - Missing Parameters: 1

Thank you, the mentioned fix works fine - should also find its way onto the 49 branch.
