HI,
This is not working in fuse 4.0.
That line is added by mistake.
And also the surprising thing is that the code throws exception at line
number 4.
1 if(object instanceof IEndPoint) {
2 tempEndPoint = (IEndPoint)object;
3 tempEndPoint.getName();
4 }
If tempEndPoint is not an instance of IEndPoint, then how it went inside the
if condition.
With Regards
