1. New Un-Initialized Module Can Receive Existing Content
    Insert a new content-module with simple-content. Without a page-reload or editing any content, pick the 'replace' feature in the toolbar and pick an existing content-item (save).
    1. The content should ajax reload with the newly added content. 
    2. If you now hit edit, the form should already contain the values of the new data-item. After validating this, hit cancel. 
  2. Initialized Module Can Replace Content
    With the module now containing a real item, again go to 'replace' and replace it with another item.
    1. The content should ajax-reload with the new data. 
    2. If you now hit edit, the form should already contain the values of the new data-item. After validating this, hit cancel.
