Call_form problem oracle form 10g

Question

Hi,
We create some forms. Next Using Call_form in menu bar we call another form, next we call another form.
Example:
Form A -> Form B -> Form C
It's working fine.
But, 'Form C' did not retrieve all data.
EXAMPLE:
'WHEN-NEW-FORM-INSTANCE' - TRIGGER
Query : "SELECT NO, NAME, MOBILE INTO :EMP.NO, :EMP.NAME, :EMP.MOBILE FROM EMP".
The above query did not work. Only Display First Record, First Column Data(:EMP.NO).
If i open the same 'Form C' in directly. It's working fine.
What is the problem? How can i solve this problem?

Answer 1

I try Your Solution, it's not working.
Code:
Declare
CURSOR PRE_CUR IS
SELECT PRE_CHAR_PRODUCT_MASTER,
PRE_NO_PRODUCT_MASTER,
PRE_CHAR_CUSTOMER_MASTER,
PRE_NO_CUSTOMER_MASTER
FROM PREFIX_MASTER;
ITEM1 NVARCHAR2(100);
ITEM2 NUMBER;
ITEM3 NVARCHAR2(100);
ITEM4 NUMBER;
BEGIN
OPEN PRE_CUR;
FETCH PRE_CUR INTO ITEM1, ITEM2, ITEM3, ITEM4;
:PREFIX_MASTER.PRE_CHAR_PRODUCT_MASTER := ITEM1;
:PREFIX_MASTER.PRE_NO_PRODUCT_MASTER := ITEM2;
:PREFIX_MASTER.PRE_CHAR_CUSTOMER_MASTER := ITEM3;
:PREFIX_MASTER.PRE_NO_CUSTOMER_MASTER := ITEM4;
CLOSE PRE_CUR;
END;
. I have another form. In this form Master/Detail . Detail have 6 Column.
When i click 'When-Button-Pressed' Trigger. I am using Cursor(Select Statement) and FOR Loop(Fetch data to fields).
The Detail block only display first 2 column data.
If i open same Form, directly(Using Form Builder) , it's working fine. Retrieve all record and displayed all column.
Why? How to solve this problem.
