Call of .NET from KF returns list

[ Edited ]

Hello everyone!

 

I am experimenting with calling .net functions from KF. I was able to make it work, but one thing seems strange to me. While debugging my KF program I found that nx_ja_session_execute actually returns list. I found workaround by using first function, but I can't get rid of feeling that something is not right here. It it working as designed? Or maybe it is supposed to return number, and I merely have somehow screwed it up?

 

By the way. I am only starting to learn KF, so the code might be quite imperfect. If you have anything to advice regarding this code, feel free to! Smiley Happy
