Vines and Climbers: Little help with this vine?, 1 by wheresthebeach

Originally posted to the plant identification on this one. I went to the county extension to identify when this stumped others there too. This vine was shown to grow 20 feet last summer. It is a fast grower with no sign of blooming. The extension office marked this as field bindweed but I am feeling that they did not take the inquiry seriously. This grew off of old wood and did not dieback. The old wood was approx 1/2 inch thick. It was perennial to zone 4/5. It looks nothing like the other bindweed that I find growing around the property and I have never seen field bindweed leave a branching system like this behind. I am willing to be corrected on this topic though. Any help would be appreciated.
