Problem defining a report to show in Reports tab of plug-in home page

Question

We are developing a plug-in for OEM and we want to add some SYSTEM reports that will be showing in Reports tab of plug-in home page.
We tried to use the PL/SQL code described in Extensibility Guide, copied the code used in some existing plug-in that we downloaded from Oracle site, but it does not work. When executing the code we receiving "PL/SQL procedure successfully completed" message, but report does not show neither in Reports list nor in Home page (reports tab does not exist).
Finally we tried to add a report containing only static text component, but with same result.
Following is the code that is executed:
DECLARE
l_target_types MGMT_IP_TARGET_TYPES;
l_param_values MGMT_IP_PARAM_VALUE_LIST;
l_target_type MGMT_IP_TARGET_TYPES;
l_report_guid RAW(16);
l_element_guid RAW(16);
l_report_title_nlsid VARCHAR2(128);
l_report_owner VARCHAR(100);
l_curr_order NUMBER;
l_curr_row NUMBER;
BEGIN
-- specify the target type associated with this report
l_target_type := MGMT_IP_TARGET_TYPES();
l_target_type.extend(1);
l_target_type(1) := 'test_plugin_57';
l_report_title_nlsid := 'Status 57_4';
l_report_owner := mgmt_user.get_repository_owner;
-- create a report definition for the report
l_report_guid := mgmt_ip.create_report_definition (
p_title_nlsid => l_report_title_nlsid,
p_description_nlsid => 'TODO: description here',
p_owner => l_report_owner,
p_category_nlsid => 'Monitoring',
p_sub_category_nlsid => 'Hardware',
p_late_binding_target_types => l_target_type,
p_late_binding_multi_targets => 0,
p_show_table_of_contents => 1,
p_system_report => 1,
p_component_name => l_target_type(1)
-- Add report so that it shows up under "reports" tab in default home page
mgmt_mp_homepage.add_report (
p_target_type => l_target_type(1),
p_report_title => l_report_title_nlsid,
p_report_owner => l_report_owner,
p_report_order => 1
-- Text
l_param_values := MGMT_IP_PARAM_VALUE_LIST();
l_param_values.extend(2);
l_param_values(1) := MGMT_IP_PARAM_VALUE_RECORD(
'oracle.sysman.eml.ip.render.elem.TextParamBean.textMessage',
'This page shows the reports related to TBD.');
l_param_values(2) := MGMT_IP_PARAM_VALUE_RECORD(
'oracle.sysman.eml.ip.render.elem.TextParamBean.textStyle',
'OraTipText');
l_curr_order := 1;
l_curr_row := 1;
l_element_guid := mgmt_ip.add_element_to_report_def (
p_report_guid => l_report_guid,
p_element_name_nlsid => 'IPMSG_STYLED_TEXT',
p_element_type_nlsid => 'IPMSG_ANY_TARGET_TYPE',
p_header_nlslid => null,
p_element_order => l_curr_order,
p_element_row => l_curr_row,
p_parameters => l_param_values,
p_targets => null
END;

Have you tried running your sql file in sql plus? Does that work? If it does execute, does the report show on the main tab but not on the target homepage or does it show in neither spot? Try hitting the refresh icon in the page to reset the cache on the Reports tab.
When you deploy the plug-in with the report file in it, did you see any errors or messages in the oms logs?
1. We do: run the PL/SQL script I posted from sqlPlus. As far as I understand it should add a report?
2. We tried all the ways of defining a report. We successfully create the report interactively with SQLs we defined. We tried to put the PL/SQL code inside the jar and deploy, to run the PL/SQL script in SQL Plus, neither report is showed in Reports list nor Reports tab is showing at all. We tried to restart OEM and computer after adding a report, it does not help...
Regarding the oms logs - where can we see that?
