Question

hi
this application uses forms 6i client server environment, graph control is being used with og.interept libray,
passing parameters run times thru forms to charts.
issue is that, system is doing uncertain behavior sometimes it shows graph smoothly but when constantly click at button it shows "OG-00609: internal pl/sql execution error"
when i close graph server and run form again, and click at button to shows charts it works properly untill shows above error again.
below is the code is being used to run charts.
begin
declare
pl_id ParamList;
query0 varchar2(256);
begin
query0 := 'select deptno, sum(sal) from emp where deptno in( '||:dept1||','||:dept2||') group by deptno;';
pl_id := Get_Parameter_List('tmpdata');
IF NOT Id_Null(pl_id) THEN
Destroy_Parameter_List(pl_id);
END IF;
pl_id := Create_Parameter_List('tmpdata');
Add_Parameter(pl_id,'dept1',text_PARAMETER,:dept1);
Add_Parameter(pl_id,'dept2',text_PARAMETER,:dept2);
if :ch_type = 'pie' then
og.interpret('e:\mas\emp2.ogd','g1',query0,true,pl_id);
og.close('e:\mas\emp2.ogd','g1');
elsif :ch_type = 'bar' then
og.interpret('e:\mas\emp3.ogd','g1',query0,true,pl_id);
og.close('e:\mas\emp3.ogd','g1');
end if;
END;
end;

Metalink Note: 1078734.6
Problem Description:
====================
You are integrating forms and graphics. You are using the og.interpret which comes with the og.pll, to update a chart.
You are using:
OG.INTERPRET('graph.ogd', 'chart', 'DO_UPDATE;', TRUE, pl_id);
You get the following error during runtime.
OG-00609 INTERNAL PL/SQL EXECUTION ERROR
Problem Explanation:
====================
1.The procedure(Do_Update) that you are referencing does not exist in the graph(.ogd file).
2. There is a bug if you are trying to specify .ogr as extension in
your graph name or no extension.
Solution Description:
=====================
1. Make sure that the name of the procedure that you are using in the
OG.INTERPRET, exists in the graph file. DO_UPDATE is not a
built-in procedure.
2. The name of the graph should have the .ogd extension only. If you
give a .ogr extension or no extension, it would give you an error.
