NULL reference, how to remove

#1

we have in our db these objects, how can we remove them (we did already a -cp Doctor):

 

 

#2

More information is needed about this NULL reference. Can we have access to the database?

What happens when you try to access the containing entity object? How many such null references do you have? Do you have any idea what operation could be related to these specific actions that made them NULL?

#3

Is there new information regarding this null reference?

If they are ordinary null values in the ArrayList then you can use List's remove method.
