Sometimes in InfoPath Forms Server when submitting your form you will get an irritating information box which comes up and says: You have made changes to the form that have not been processed. We will process the changes and show the form again. After that you have to click "Submit" again.

You then have to click ‘Submit’ again for the form to submit .

To get rid of this message, and I know you want to, do the following:

  • Go to menu item ‘Tools’ then select 'Form Options'. Select on the list on the left 'Compatibility'.
  • Select the option to 'Design a form template that can be opened in a browser or InfoPath'
  • Now go to your form, select the control that is causing the problem. Right click on it and select 'Properties'
  • Go to tab 'Browser Forms' and change Post Back Settings to 'Always'. Note this tab would not have been here had we not changed the Compatibility options. 

I am sure this will help someone someday :)
