### **Steps to reproduce:**

1. On the project overview page, add a widget "Calendar"
2. Have at least one Work Package that is shown in the calendar Begin of the insertion(soEnd of the insertion Begin of the deletion  (soEnd of the deletion start date should be set before the current week, end date after the current week)
3. Login with a user, who does not have permissions to see Work Packages
4. Go to that project overview page

### **Actual Behavior**

* There is an error message on the whole page, saying that the view is faulty.
* The message does not reveal what exactly went wrong and it looks like the page is Begin of the insertionbuggy.End of the insertion Begin of the deletion buggy. End of the deletion

Begin of the insertion<img class="op-uc-image op-uc-image_inline" src="/api/v3/attachments/18211/content" alt="">End of the insertion Begin of the deletion End of the deletion

### **Expected Behavior**

* Begin of the insertionAnEnd of the insertion Begin of the deletion Ideally anEnd of the deletion explaining error message would be shown within the widget like it is done for the graph widgets:

Begin of the insertion<img class="op-uc-image op-uc-image_inline" src="/api/v3/attachments/18212/content" alt="">End of the insertion Begin of the deletion 

* Another possible solution is to leave the calendar empty and do not show any error message at all. This is how most of the other widgets handle missing permissions.End of the deletion
