Hey,   I hope this is possible because this would be so awesome for our Application Monitoring. So our API returns an object that contains a List of that I need the last element. So I created a getter chain like this for testing of the first element:   getBody().getRoute().get(int/0).getLength()   and this worked.   My problem is that I can't seem to get the correct syntax right on how to get the last element. My last tries were the following: getBody().getRoute().get(int/ReturnValue.getBody().getRoute().size()-1).getLength() getBody().getRoute().get(int/this.getBody().getRoute().size()-1).getLength() In both cases the Data Collector displays:  [CANNOT EVALUATE: Error getting data from specified method parameter] Is there something I'm missing? Or is this simply not possible?   Kind regards ... View more
