I'm trying to edit an InfoPath form for an external list from SharePoint Designer. After clicking on the "Design Forms in InfoPath" button I get the following error: "Object 'blablabla.rem' has been disconnected or does not exist at the server."
I have to customize the edit form for 12 external lists and I have this message for 10 of them. I tried deleting and creating them again to no avail. I can view and edit the data of all of them through the standard view/edit forms in SP.
What have I done wrong ? What can I do about it ?
