Binding bracket operator

Could you help me bind a bracket operator in my custom class? By looking at the macro definition, I figured that something like this should work:

void MyObjectArray::bindInterface() const
{
  bindTypedProperty( length, int, &MyObjectArray::GetLength, nullptr );
  // ...
  bindBracketOperator( MyObject, MyObjectArray, int );
}
int MyObjectArray::GetLength() const
{
  return this->length;
}
MyObject MyObjectArray::operator[]( int index ) const
{
  return this->objects[index];
}

but when I try to use it in FlexSim I get

Could not resolve correct operator for [] operation. Left side type is MyObjectArray, right type is int

and also the [...] does not show up in code completion.
Is there a bug or did I misinterpret the arguments to bindBracketOperator?

Thanks!

As a side note: I wanted to return by value from operator[], is that allowed as long as MyObject is copyable or does FlexSim always need a reference?

Never mind, I figured it out. The code is correct, I just forgot to

bindClass( MyObject )

so probably FlexSim was confused about that.
