Hi,
We have created a CAP Service application by using UI elements created using annotations. To achieve maintenance (Create & Edit) functionality, we have used '@odata.draft.enabled' as well.
But during EDIT functionality, we are getting "500 Internal Server Error" on clicking BACK button without doing any SAVE. Below are the detailed steps with screenshots to elaborate the error.
Note: a) During EDIT functionality, if we change any field and click on SAVE; then we are NOT getting any Error
b) We have implemented the same code in "SAP TRIAL account"; but there we are NOT facing this 500 Error.
1) Below is the Main Screen of our application. Now click on any row (as shown by RED color arrow) to get the detailed view.

2) Below is the detailed view. Now click on EDIT button.

3) Now click on BACK button without making any changes in the editable fields or without clicking on SAVE button (as shown by RED color arrow).

4) Below is the 500 Internal Server Error we are getting.

More details of above error.

Kindly help/advise.
Thanks.
