I think I'm getting insane. I have a Forms Library.
The form has been perfectly working. It has a few dropdowns populated from SharePoint lists
Suddenly I can't open a new form
Existing forms work fine. Preview works fine but not when I (or anybody else) clicks New
"InfoPath cannot open a new form. The form cannot be opened because some external data cannot be retrieved. To fix this problem, contact the form designer.
The query cannot be run for the following DataObject: Disciplines. The SOAP response indicates that an error occurred
Server did not recognize the value of HTTP Header SOAPAction..."
Nothing has been changed in the code or Form_Load rules. My guess would be Security...Library Settings/Pemissions... Any ideas?
