Content Type with ezmatrix.
1. Go to Content/Content structure and click Create
2. Select CT from preconditions
3. Add some new rows in ezmatrix field and leave them empty
4. Click Publish
Preview displays that ezmatrix field is empty - OK. But When I go back to edit mode, there is only one empty row.
If we allow user to add and publish empty rows, maybe we should keep them when he's going back to edit mode?
