REP-0503: You did not specify the name of a report

Question

I am getting the above error while calling a report from a form in Oracle 9iDS.
I have created anode in the report node of the form(TESTREP1) this is same as my report rdf name which is stored in C:\temp\9ids folder, report_path points to this folder,OC4J is start, in the properties of TEST_REP1 in the form i have set:
filename C:\temp\9ids_test\test_Rep1.rdf
My code on a when-button-pressed trigger is
DECLARE
     repid report_object;
     v_Rep varchar2(100);
BEGIN
repid := FIND_REPORT_OBJECT('TEST_REP1');message(get_report_object_property(repid, PORT_FILENAME));
-- i can see this message showing the filename as
--C:\temp\9ids\test_rep1.rdf
v_rep := Run_report_object('TEST_REP1');
message('test report')
-- i can see this message but fails to run the report
--with REP-0503
exception
     when others then
     message('Error: '||sqlerrm);
END;
where am i wrong?

The following code also doesnt work
DECLARE
repid report_object;
v_Rep varchar2(100);
BEGIN
repid := FIND_REPORT_OBJECT('TEST_REP1');
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_DESTYPE, 'cache');
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_DESFORMAT, 'pdf');
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_COMM_MODE, ASYNCHRONOUS);
v_rep := RUN_REPORT_OBJECT(repid);
exception
     when others then
     message('Error: '||sqlerrm);
END;
