Object reference not set error message when i try to add Taginstance in Filter properties of a control


I did a recording of the control then i open its filter properties and removed all information. then i open it search properties and try to add Taginstance in it search property and i got an Error "object reference not set to an instance on an object " and VS quits after this ?

  1. delete tag instance from filter properties
  2. save it 
  3. add tag instance in search properties (it will throw exception and Exit VS  that's fine
  4. re-open that file and go to search properties and Add Tag instance now it will add without exception
