Hi, I read around a bit and did some changes. Instead of using an *ObjectTemplate *directly, for wrapping the C++ object, I created a *FunctionTemplate *first, used *SetClassName()* and then called *InstanceTemplate()* to create an *ObjectTemplate *from it. All handlers were set on this *ObjectTemplate*. Now the name is getting displayed for the returned object. :) However, there is a catch. When I set the callback *SetCallAsFunctionHandler()* on the *ObjectTemplate*, it stops working and starts showing up as *f anonymous()*. I need this because I want to further call the object as a function. ibon, can you please check if *SetCallAsFunctionHandler()* is set for your *ObjectTemplate*?
