问题
We upgrade our TFS test environment from 2015.1 to 2017.3 . We have Multi Value control in our Work Items, after the upgrade the Work Item form was empty (unless the tags), and the error on the console was about the multi value control. I downloaded the Multi Value extension from the market place, but is only for the new form (WebLayout), and we not want to move to the new form yet.
I go to Legacy Extensions and disable the old multi value control extension, and now we the work item is appear, unless the fields with the multi value ("Cannot create work item control of type "MultiValueControl"). I saw on the old extension website that have a newer version of this (1.3.2.5) but I didn't find a download to this file anywhere. Is there a way to make the multi value work on the old form? or we must to use the new form?
