I use IED Explorer 0.80d for connecting to IED. I can establish connection fine and ask for reading data with right click on Data Item in IED View (MMS). So far so good, I get new data.
When I drag and drop the same Data Item to Poll View it appears inside Poll View, but when I press Update button (two green curved arrows) I get nothing. But I am 100% sure, network request-response are working fine, because Wireshark detects network activity and inside CaptureView I get packets. In the log view I get Object reference not set to an instance of an object:
I discovered that with single item in the Poll View poll works fine. The error appears after adding more than one item. Once appeared the error persists until disconnection.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

What does it mean ? How can I debug the problem ?
