I am using Sharepoint 2010 and Nintex, but not the SP designer. I experience an interaction issue with webparts on a web part page.
On my web part page, I have a list web part which is shown correctly. When I add a Nintex form web part, the headlines of the list web part disappear. When I delete the Nintex form web part, the headlines are back where they belong.
The web parts are not connected and tried out all setting options. Is that a bug or is there a checkbock to activate?
