"Verify that all properties have valid integer values within the range of -32,768 to 32,767. Make sure all non-nullable (cannot be left empty) fields have valid values. This problem could be resulting when a string ID does not have a value for each supported language. In most cases, you will provide a value only for the default language while authoring your setup, therefore this error will result because the new ID will have blank values for the other languages. Check that you did not accidentally create empty rows in any tables while using Power Editor."
Have I missed something or? How do I track down this error. I've tried deleting new components and features, but that doesn't help at all. I havent's used the power editor, as the message insinuates.
