Steps to reproduce

1.  Make use of the attached sample tourGuide: content-type and content-app 
2. Create a new item in tourGuides app (STATUS IS RED)
3. Publish the item (Status is GREEN)
4. Edit the submodel properties of the item (Contact and address fields) and save changes

Expected results

After the modification, status is shown as yellow

Actual results

Status is still green, which is confusing as it seems as if it was already published when it is not.

Development Notes

If one of the fields of the main model is modified, status is correctly shown in yellow. Modifications are actually saved in JCR as well as the modification dates. It seems that only modifications from the root model are considered
