Search Form Problem

Question

Hi
I have a Form name BPRESTATARIAS with two blocks.
A block BUSCAR that has a text item BUSCAR.
And another block PRESTATARIAS with origin of data in the table PRESTATARIAS.
SQL> desc prestatarias
Name Null? Type
CODIGO_PRESTATARIA NOT NULL NUMBER(6)
NOMBRE_PRESTATARIA NOT NULL VARCHAR2(50)
The clause where of this block = NOMBRE_PRESTATARIA LIKE :BUSCAR.BUSCAR||'%'
In the WHEN-NEW-FORM-INSTANCE i have this code:
DECLARE
half_sec NUMBER(3):= 50;
timer_id TIMER;
BEGIN
timer_id := create_timer('key_timer',half_sec,repeat);
:global.txt := '';
END;
In the WHEN-TIMER-EXPIRED i have the following code:
DECLARE
Timer VARCHAR2(100);
BEGIN
timer := get_application_property(timer_name);
IF timer = 'key_timer' THEN
     IF :system.cursor_item = 'buscar.buscar' THEN     
     IF ltrim(rtrim(:global.txt)) <> ltrim(rtrim(:buscar.buscar))
     OR (ltrim(rtrim(:buscar.buscar)) is null and :global.txt is not null)
     OR (ltrim(rtrim(:buscar.buscar)) is not null and :global.txt is null) THEN
          :global.txt := ltrim(rtrim(:buscar.buscar));
          GO_BLOCK('prestatarias');
          EXECUTE_QUERY;     
          GO_BLOCK('buscar');
     END IF;
     END IF;
END IF;
END;
The forms work, but for example when BUSCAR.BUSCAR = 'MEDIC ', and a timer expires, BUSCAR.BUSCAR change to 'MEDIC';
Why?, how I suppress this problem?.
Thanks.

Forms strips trailing spaces on items when interacting with the database.
