Explain the logic of why connections *-1 and the attributes of one entity can be selected and not the other way also

Hi, I got a question about the option to choose an attribute on a newEdit page of a other Entity. I will give a example below: So what i did is the a data grid of the entity Employe, and the genereted a new page. On this page i can select a text box and select a attribute of the entity Lunch. If i do it the other way when i put a data grid with the entity lunch and generated a newEdit page i see this: On this newEdit page i can't select the attributes of the entity Employee. Can anybody explain this logic why can i select the attribute of the *-1 relation  on one entity and not the other.

Because you can have multiple employees on your lunch, you cannot put the employees as attribute on the page. This is only possible if the association would be 1-1. To be able to modify you employees on the lunch, you can try the datagrid or list-view widget.
