Oracle Forms

Hi

I have one screen with 4 tabs. All the data coming from one single table.

Columns are distributed based on certain categories into different tabs.

The data is loading properly on when-new-form-instance trigger, it is populating the data in first tab.

In when-tab-page-changed I have written somthing in similar as below

BEGIN
v_Tab := GET_CANVAS_PROPERTY('CAN_TABS', TOPMOST_TAB_PAGE);

CASE v_Tab
WHEN 'PG_1' THEN
:TXT_HIDDEN_TAB_NAME := 't1' ;
.....
.....
WHEN 'PG_2' THEN
:TXT_HIDDEN_TAB_NAME := 't2' ;
WHEN 'PG_3' THEN
:TXT_HIDDEN_TAB_NAME := 't3' ;
Go_ITEM('column11');
WHEN 'PG_4' THEN
:TXT_HIDDEN_TAB_NAME := 't4' ;
Go_ITEM('column33');
END CASE;

EXCEPTION
WHEN OTHERS THEN
MESSAGE('Error :' || SQLCODE || ' - ' || SQLERRM);
END ;

So when I click in tab 3 I get an Error as
FRM-40112 Attempted go_item to non enabled item <BLOCK_NAME.ITEM_NAME> Eg: BLK_test.column11

I am sure someone might have faced with similar situation

Do suggest :)

Thanks and Regards
