I am running SharePoint 2010 and Nintex 2.3.14
I have an InfoPath form which writes to a SharePoint List. The SharePoint List has a number of Nintex workflows attached to it. When I try to submit the data from the form to SharePoint I am getting inconsistent results. Sometimes the data submits and sometimes it fails with a 401 error. All the items have the same permissions, I am set up as Owner of the site and Site Collection admin. I have updated the button in InfoPath to submit a second time if there is an error - and this seems to fix the problem - i.e. if the submit fails the first time it will always succeed the second time.
In InfoPath I have the option to Use Web services or not. If I do not use web services the updates work ok every time - but the Nintex workflows are not triggered with the change in data. If I opt to use Web services the inconsistent update occurs - but the Nintex workflows will trigger once the data is updated.
Has anyone an idea about what is going on.
Also I have tried creating a SharePoint designer workflow on the same site collection - as a test - and I cannot get it to start. Is it possible to have SharePoint designer workflows working on the same site collection as Nintex workflows ?
