Perhaps one more bug when using wrapper in XE2. I don’t have ability to test 
it under different version of Delphi.

File: “JSINTF.PAS”

procedure TJSClassProto.DefineJSClass(AClass: TClass; AClassFlags: 
TJSClassFlagAttributes);

From
{
    if exclude or (Length(ip.ReadMethod.GetParameters) = 0) or (ip.Visibility < mvPublic) then
      continue;
}
To
{
    if exclude or (ip.ReadMethod = nil) or (Length(ip.ReadMethod.GetParameters) = 0) or (ip.Visibility < mvPublic) then
      continue;
}

Sometimes, for some method, for example for some “Destroy” method 
ip.ReadMethod is nil, therefor calling ip.ReadMethod.GetParameters cause

Fixed, but this looks like xe2 rtti  bug, returning destroy method as an a 
method for indexed properties dosen't make sense @ all
