Input fields for CRUD Operations in a Fiori Elemets List page not showing

Hi ,

I was following the totorial on ABAP in cloud foundry (https://developers.sap.com/tutorials/abap-environment-transactional-enablement.html )

Now when Bookings service from Eclipse is published and tested from there, it works fine. A list is shown and on pressing the "+" button a form opens where the data for a new dataset can be maintained. That works fine also for delete and update.

In WEbIDE now choosing the list report template with this service also shows the list of entries. But when clicking the "+" button, a page with no fields opens. On save that creates an entry in the table (with blank data though).

How can the input fields be shown for the entity? Is that done by annotations ?

Any help is appreciated !
