I recently upgrade our SharePoint 2010 to SharePoint 2013 and now I'm having trouble with an InfoPath form based on a Business Connectivity Services external list.
For some basic background. I have an External Content Type called "Project Status". It's a simple SQL table with default CRUD operations created using SharePoint Designer. I the "Create Lists & From" button to create a list called "Projects" from. This list also uses the InfoPath form option. This was all created back in SharePoint 2010. Within the InfoPath form I have a field that was converted to a Drop-Down list box. When everything was still SharePoint 2010/Office 2010 I could update the available entries for this field and then republish the form. This has since broken since upgrading to SharePoint 2013.
In SharePoint 2013 the Projects list still properly reads the data from the SQL database. The existing InfoPath form still works for update operations. I now have the need to update the available entries for my drop-down field. I can open the list and the form using SharePoint Designer 2013 and InfoPath 2013. I can modify the field properties but when I attempt to publish the form back to SharePoint I get the following error:
The current operation requires Business Connectivity Services client components. Install Business Connectivity Services client components and try again.
I have ensured the Business Connectivity Services component is installed with Office 2013. I also ensured that .NET Framework 3.5 SP1 was installed prior to Office 2013 installation.
I am currently trying to resolve this on a system with Windows 8.1, Office 2013, SharePoint Designer 2013. I have ensured that all software is up to date. I have also experienced this issue with another Windows 8 workstation and the SharePoint 2013 server itself (Server 2012).
Also, just for reference, I have tried creating a new External Content type to the same SQL database and table, creating a new list and InfoPath form and the issue still exists when attempting to publish the InfoPath form back after editing. I'd appreciate any help you can provide.
Thanks,
