XML Charts - Unwrapped

Question

I made the package available for download here:
http://htmldb.oracle.com/pls/otn/f?p=31517:58
There are three additional changes:
1. x- and y-axis titles may be specified,
2. no UTL_FILE package access necessary by default,
3. functions, for converting axis values may be specified.
A demo is available here:

Hello
I´m playing around with the xml-charts for a few days, but cant get them to work.
I think i make some very simple mistake.
Installation according to the readme-file was ok.
Granted all things required.
Made a debug-dir.
No errors or invalid objects there.
created a new page in my demo application.
created a hidden item
created a computation with static assignment for the item.
created a report with the same query and it works.
created a pl-sql-content with the provided block. checked it against that, what the "SELECT xml_chart_pkg.get_chart_plsql FROM DUAL;" returns. Looked equal.
running the page, show me (after a while) a orange background with the following message:
Loading<xml_chart_pkg.chart_region_pr?app_user_in=APEX_PUBLIC_USER...
(i´m not able to read more, because the message is cut on the edge)
debug = 'Y' shows no error (any more) but nothing is in the created oracle directory
The session tells me that the sql is in the hidden item.
And it tells me, that i have collection some values in the collection similar to my test-report.
Collection Name | Sequence | C001 | C002
CSTACKEDCOLUMN230582657841003510010 | 1 | OHare | 500
CSTACKEDCOLUMN230582657841003510010 | 2 | LaGuardia | 4300
CSTACKEDCOLUMN230582657841003510010 | 3 | Bradley | 500
CSTACKEDCOLUMN230582657841003510010 | 4 | Logan | 790
CSTACKEDCOLUMN230582657841003510010 | 5 | Hartsfield | 47798
CSTACKEDCOLUMN230582657841003510010 | 6 | Dulles | 1240

h3. My environment is:
oracle db 11g
apex 3.2
installed with mod_plsql not epg
all running on windows 2008 server x64
h3. my sql in the hidden item is:
select cu.CUST_LAST_NAME as CUSTOMER, sum(o.ORDER_TOTAL) as ORDER_TOTAL
from DEMO_ORDERS o, DEMO_CUSTOMERS cu
where o.CUSTOMER_ID = cu.CUSTOMER_ID group by cu.CUST_LAST_NAME
h3. my pl-sql for the chart is:
BEGIN
xml_chart_pkg.xml_chart_pr(
item_for_query => :P10_SQL_HIDDEN, --item storing your chart query
chart_type_in => 'stacked column', --your chart type
sort_series_in => 'ASC', --how to sort series
width_in => 600, --width of your region
height_in => 450, --height of your region
debug_xml_in => 'N', --using debug option
xml_output_dir_name_in => 'chart_debug', --debug output directory
chart_template_in => 'MY_TEMPLATE,SWITCH_COLORS', --templates to be used with your chart
chart_standard_ignore_in => 'N', --ignore all standard settings
link_type_in => 'P', --link type P for popup and R for redirect
page_to_pass_values_to => '10', --page to pass values in the link
request_in => 'SORT', --request to pass within link
items_to_pass_values_to => 'P200_ITEM', --items to pass values to, comma delimited
values_to_pass_to_items => '_category_', --values to pass to items, see XML reference
link_pop_up_w_in => '1000', --link popup window width
link_pop_up_h_in => '800', --link popup window height
chart_background_color_in => '#ededd6', --region color
unique_id_in => NULL, --unique string to identify your chart if the same chart
--type is used on the same page
turn_caching_on => 'N', --if your want to keep the session result per chart,
--use collection to store the result set
default_directory_xml => '/i/charts/', --if your want to specifiy another directory,
-- you need to determine this parameter
axis_val_conv_function => NULL, --if your want to convert axis values, you may include
--any function here and it will convert your values to
--whatever (standard functions or your own custom)
x_axis_title => NULL, --title of the x axis
y_axis_title => NULL --title of the y axis
END;
I hope i have not over-read the solution in another thread.
Thanks for any help.
