FORALL bulk insert ..strange behaviour

Question

Hi all..
I have the following problem..
I use a FORALL bulk Insert statement to insert a set of values using a collection that has only one row. The thing is I get a ' ORA-01400: cannot insert NULL into <schema>.<table>.<column>' error message, whereas the row has been inserted into the table!
Any ideas why this is happening?

Here is the sample code..
te strange thing is that the cursor has 1 row and the array gets also 1 row..
FUNCTION MAIN() RETURN BOOLEAN IS
-- This cursor retrieves all necessary values from CRD table to be inserted into PDCS_DEFERRED_RELATIONSHIP table
CURSOR mycursor IS
SELECT key1,
key2,
column1,
date1,
date2,
txn_date
FROM mytable pc
WHERE
-- create an array and a type for the scancrd cursor
type t_arraysample IS TABLE OF mycursor%ROWTYPE;
myarrayofvalues t_arraysample;
TYPE t_target IS TABLE OF mytable%ROWTYPE;
la_target t_target := t_target();
BEGIN
OPEN mycursor;
FETCH mycursor BULK COLLECT
INTO myarrayofvalues
LIMIT 1000;
myarrayofvalues.extend(1000);
FOR x IN 1 .. myarrayofvalues.COUNT
LOOP
-- fetch variables into arrays
gn_index := gn_index + 1;
la_target(gn_index).key1 := myarrayofvalues(x).key1;
la_target(gn_index).key2 := myarrayofvalues(x).key2;
la_target(gn_index).column1 := myarrayofvalues(x).column1;
la_target(gn_index).date1 := myarrayofvalues(x).date1;
     la_target(gn_index).date2 := myarrayofvalues(x).date2;
la_target(gn_index).txn_date := myarrayofvalues(x).txn_date;
END LOOP;
-- call function to insert/update TABLE
IF NOT MyFunction(la_target) THEN
ROLLBACK;
RAISE genericError;
     ELSE COMMIT;
END IF;
CLOSE mycursor;
END IF;
FUNCTION MyFunction(t_crd IN t_arraysample) return boolean;
DECLARE
BEGIN
FORALL x IN la_target.FIRST..la_target.LAST
INSERT INTO mytable
VALUES la_target(x);
END IF;
