The creation of content-on-the fly does only work in one iteration. Should work in multiple iterations. As it is now when trying to relate content in the creation of object nothing happens when you push the relate button.

Example:
1. Add embed
2. Create
3. The new object being added have a realation list
4. Pushing the button to relate objects, nothing happens

In step 4, you should be able to relate objects (and also create the object on the fly)

Basicly: Content-on-the fly should be possible to nest in multiple levels.
