We have a SharePoint onprem list with a connection to Nintex form.
The SharePoint list has the select button, and if you click any select link 1st, no Nintex form shows on the page. You have to click a 2nd link to get the Nintex form webpart to display.
Please advise how we can get the first click to populate the Nintex form.
I tried the same, I was able to get the specific item populated in the Nintex Form with single click only, here is my connection configuration (left one - from list web part to List Form, right one - From List Form to List Web part) . Do you have any other scripts running on the page? Click on F12 to show Dev Tool bar and go to Network tab and see what calls are being made when you click on an item.
