Re: udcx Data Connections moved from one site to another cannot be accessed

Yah, I've had similar issues in the past - usually for some reason the relative path isn't resolving correctly from a subsite. In the manifest, search for xsf2:connectoid to find the info on the UDCX files. I think the issue will likely be with the siteCollection or source attribute there.

udcx Data Connections moved from one site to another cannot be accessed

We have an InfoPath form hosted in a SharePoint 2010 Forms Library. When loaded, the form reads data from three SharePoint lists, all in the same site. The Data Connections used to the read three lists are stored in .udcx files in a Data Connection library, also on the same site. These files were created in InfoPath Designer by using "Convert to Connection File."

We need to make a set of major changes without impacting our users, so we've created another site and copied the entire contents of the application to the new site. We want to use the site copy to develop the new capabilities, then move the changes back to the main production site. As expected, the copied form failed to load initially, and so we updated all the data connection URLS in the form template itself, and all the URLS in the .udcx files, to point to the lists on the copied site. We then published the updated form into the copied site. However, the form still fails to load.

The errors that are displayed differ depending on how the form is loaded. This is the message generated by opening the form in a browser:

An error occurred while accessing a data connection (.udcx) file that is required for this form to function correctly. The file cannot be found or you do not have permissions to access it.

Correlation ID:5adb6279-fd8c-4be1-a556-2851b657c08a

Or this one, generated by trying to preview the form in InfoPath Designer:

Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.
<detail><errorstring xmlns="http://schemas.microsoft.com/sharepoint/soap/">
List does not exist.
The page you selected contains a list that does not exist. It may have been deleted by another user.
</errorstring><errorcode xmlns="http://schemas.microsoft.com/sharepoint/soap/">0x82000006</errorcode></detail>

We have verified that the user account being used has the correct permissions, and that the error occurs even for site collection administrators. The lists exist, are populated, and the user has permission to all of them.

When the form is edited in InfoPath Designer, all of the data connections show the correct path to the .udcx file library and the correct filenames. All of them are say they are Relative link types. But all of them are generating this same error. We've scoured the manifest.xsf and all associated files for URLS that point to the old site, to no avail. We are trying to avoid deleting the data connection files and recreating them, since doing so will delete all the form fields and rules that rely on them. Fixing those and retesting would be time prohibitive. Can you provide any insight on what may be the issue and how to resolve it?

Thanks in advance.
