CGI call to Oracle Reports with embedded graph not executing triggers on bars

Question

I have the following function which is suppose to change the color of the bars in subgroups.
PROCEDURE Set_Group_Color(elem IN og_object, a_group_index number) IS
v_color varchar2 (32);
v_temp og_object;
v_idx number;
BEGIN
v_temp := OG_GET_OBJECT ('GRPG_NM1_GRPG_CNT_legend_label');
v_temp := OG_GET_PARENT (v_temp);
v_color := color_list (a_group_index);
og_set_bfcolor (elem, v_color);
og_set_ffcolor (elem, v_color);
v_idx := a_group_index * 2 + 1;
v_temp := OG_GET_CHILD (v_temp, v_idx);
-- 0 = legend_frame
-- 1 = border of color box (no name)
-- 2 = GRPG_NM1_GRPG_CNT_legend_label
-- 3 = border of color box of next group
-- 4 = GRPG_NM2_GRPG_CNT_legend_label
OG_SET_BFCOLOR (v_temp, v_color);
END;
This function is called from the format trigger of the bars themselves. The code works the way i want it to in the ORacle Graphics designer but when i executed from the web the triggers are not executed at all!!!
Am i forgetting to do something? Is this a known bug. When i put a format trigger on the graph axis-labels they execute correctly in both the designer and the web. But the bar triggers do not!

Answer 1

1. Along with this version of Reports you should find the reports server (r30mts on unix). This will allow you to deploy your reports on the web - on HP/UX or Solaris.
2. To web deploy you have:
Web Browser --->
Web Listener + Reports CGI ----->
Reports Server -->
RDBMS
3. You don't need the cartridge if you are using the CGI.
For more information, please look at the Reports Server Configuration whitepaper, available on OTN - it was written for Reports 6.0, but the concepts and architecture are applicable for Reports 3.0
