ORA-21700: object does not exist or is marked for delete - sql

Question

I have package with Period and TableOfPeriod types:
TYPE Period
IS RECORD
( StartPeriod Date,
EndPeriod Date
);
TYPE TableOfPeriod
IS TABLE OF Period;
and in this package I have three simple function:
FUNCTION Temp1
RETURN TableOfPeriod IS
returnedValue TableOfPeriod := TableOfPeriod();
BEGIN
returnedValue.extend(1);
returnedValue(1).StartPeriod := sysdate-100;
returnedValue(1).EndPeriod := sysdate;
RETURN returnedValue;
END Temp1;
FUNCTION CalculateFine
return VARCHAR2
IS
freewillLockTableRP TableOfPeriod:=TableOfPeriod();
compulsoryLockTableRP TableOfPeriod:=TableOfPeriod();
BEGIN
--for testing
compulsoryLockTableRP:=Temp1();
FOR i IN compulsoryLockTableRP.FIRST..compulsoryLockTableRP.LAST LOOP
IF(((compulsoryLockTableRP(i).EndPeriod - compulsoryLockTableRP(i).StartPeriod)>1)) THEN
BEGIN
-- RAISE_APPLICATION_ERROR(-20001, 'Hello world');
SELECT T111.StartPeriod StartPeriod,
T111.EndPeriod EndPeriod
bulk collect into freewillLockTableFull
FROM TABLE(DistributeDaysByPeriods(compulsoryLockTableRP, 5)) T111;
END;
END IF;
END LOOP;
/*SELECT T111.StartPeriod StartPeriod,
T111.EndPeriod EndPeriod
-- BULK COLLECT INTO compulsoryLockTableRP
bulk collect into freewillLockTableFull
FROM TABLE(DistributeDaysByPeriods(compulsoryLockTableRP, 5)) T111;*/
--===========
--SOME OTHER PROCESSING
RETURN 'Ok '
|| '#r';
EXCEPTION
WHEN No_Data_Found THEN return 'No data found#g';
-- WHEN OTHERS THEN RETURN SQLERRM;
END CalculateFine;
When I execute this function, I have next error:
"ORA-21700: object does not exist or is marked for delete ORA-06512:
at "MyPackageName", line 1181 ORA-06512: at line 1
21700. 00000 - "object does not exist or is marked for delete""
where 1181 line is a line with Select statement of CalculateFine function. Can anybody tell me, whats wrong and how I can solve this problem?

Answer 1

Check if you have in the same folder where your package is located a file with the same name but with an extention *.~sql (e.g.: your_file_name.~sql). I had the same error but after I have deleted an *.~sql file I could compile my package without ORA errors.
