Hello, I added some external data connection to my form (not Sharepoint). I can publish (administrator approved) my form without problem. I can upload the template on the central administration too. But when I connect a field to this external data connection when I upload the template on the central administration I have an error message : "Error Object reference not set to an instance of an object. Troubleshoot issues with Microsoft SharePoint Foundation. " If I do the same form with another publish way (not administrator approved but Form Library" it works. Help me please! Thank you

Interesting - is your data connection a UDCX?

Yes it is. I added my data connection in the form and after I convert it in udcx file. I approved this udcx file in the library which store the files. Do you have an idea?

So - the UDCX library is on the same site as you've activated the content type from the Admin Approved form to?

Yes that's it. I don' know what can I say which help to find the solution..

I'd save a copy of the template that is being admin approved as source files. Then you can look in the manifest.xsf with a text editor to see where the form is looking for the UDCX. You could also try the admin approved form in the browser and check the SharePoint ULS logs to see if there is more info there.
