An error occurs when a user tries to save content using a content class that has an object relation list marked as required.

The user after creating the content must save the content as a draft first before publishing the content or the object relation list property that is being set must be set to not required to enable a user to directly publish their content.

Steps to reproduce

1. Create a content class with a required object relations (object relation list) attribute, selection method: list with check boxes.
2. Create a new instance of the content class and select a value for the object relation.
3. Click Publish (do not save as a draft first) and the error will occur:
"Required data is either missing or invalid:

• <attribute name>: Missing objectrelation list input."
