Application Express :: Pie Charts Not Displaying
Jun 25, 2013
I just upgraded from APEX 4.1.1 to APEX 4.2.2All is good, but I can't create pie charts. Pie Charts never worked for me, but I waited until 4.2.2 to try again. Still will not work. I imported the workspace from my previous APEX version,so something must not be set correct in my workspace. I can create the pie chart on apex.oracle.com
Here's my info:- Application Express Version: 4.2.2- Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production- OS Red Hat Enterprise Linux Server release 5.9- WebLogic 10.3.5- Apex Listener 1.1.3.243.11.40

I just upgraded my APEX 4.0 application to 4.2, and ran the utility to upgrade my charts to HTML5. After completing the upgrade, I noticed my charts no longer displayed in the region.
I am currently using IE9 to view the application, since that's the browser over 90% of my users have. Is there something more I need to install?

I am using "Function Returning SQL Query" (as query is dynamic) to draw the bar chart (flash).
I am facing some issues while trying creating a BI report for this chart.
Issue is : In Shared Components -> Report Queries : Its only expecting an SQL Query.
Do we have any ways to define a "Function Returning SQL Query" over here ? Note that, If using a static SQL both charts / BI reports are working fine with out any issues.

I have a requirement create graphs, charts and maps based on data from a data warehouse (dw).
As I see things, there are two possibilities: Graphs, charts and maps based on an XML fileGraphs, charts and maps based on Oracle tables Both would contain small data sets that will allow for quick response.
The intent of these graphs, charts and maps is to generate a dashboard that would allow the user to quickly drill down to the desired warehouse data. The proof of concept has already been validated using the Oracle table scenario.
My question is whether or not this could be accomplished reading xml files for generating the same set of dashboard items? My Oracle database and APEX environments configuration are as follows:
NLSRTL 11.2.0.1.0 Production Oracle Database 11g Enterprise Edition 11.2.0.1.0 64bit Production PL/SQL 11.2.0.1.0 Production TNS for Solaris: 11.2.0.1.0
ProductionApplication Express 4.2.2.00.11APEX Listener Release 2.0.2. / Tomcat
An Oracle database directory has been setup and is accessible to our APEX application.

whether the overlapping Multiple series charts are possible in Oracle APEX or not .
I am trying to create two graphs for two data sets , one as marker and another as line , but its giving me issues such as
1) X axis is taking all the points of the first series suppose(
1,5,10,180) itsplotting these first . and its then starting labeling
the x-axis for another one which has values like
(20,50,100,1000,15000)
so my X-axis is now ---> 1,5,10,180, 20,50,100,10000,150000
In case i make my marker chart series as the 2nd sequence , then its drawing all the markers on the right side of the chart .
[URL].........
Workspace:- NR_WORKSPACE
Username:-user1
password:- H123$
whether this thing is achievable in oracle apex or not , is there any work around ?

I am in the middle of upgrading my application to Apex 4.1 from 3.2.1. I have been using the default delete message and now it won't work.
<script langues="javascript" type ="text/javascript"
<!--
htmldb_delete_message='"DELETE_CONFRIM_MSG"';
//-->
</script>
button action
redirect to url ----> javascript:confirmDelete(htmldb_delete_message,'DELETE_RATING');
now all I receive is a message from the webpage, instead of the message.

I am using custom authentication with APEX 4.1.1 and I want to display custom error messages on the login page if authentication fails. In my authentication function I'm using apex_util.set_authenication_result to set a result code (code below).
I've tried to use the apex_util.get_authentication_result on the login page to hide and show custom messages but it's not working. I don't believe the apex_util.get_authentication_result is actually obtaining the result?
FUNCTION verify_user(
p_username VARCHAR2,
p_password VARCHAR2
) RETURN BOOLEAN
IS
v_ctr NUMBER;

After setting up a data entry page,The logic in my page requires that all the records in my tabular form should be displayed .The tabular form is based on a collection, and the user selects rows through a checkbox.Any reload of the page due to pagination will break the logic, as some calculation and display events occur during page load, based on the previous page.
I need to display about 25 rows.I have changed the report attribute to display 50 rows, but it displays rows only up to the bottom of the screen, i.e. 11 rows.
Unfortunately I only just added some new rows and saw this behaviour else I would not have gone that way, as I expected APEX to display all rows if required.

APEX 4.1 / 11g
Theme 21
I have a page with about 8 Classic reports. 4 of them percentage values, 4 totals. I have one RG with a Percentage or total option. When I select the percentage radio, it should hide all the total regions. When I select the totals radio it should hide all the percentage regions. Simple? So I thought. This is what I did.
1. Created a RG(P2_RG) -> Page value is redirect and set value.
2. STATIC:Percentage;P,Total;T
In the RG, I have created a normal DA which has the true and false events as follows.
Event -> Change
Items -> P2_RG
equal to -> P
In the true actions, I have hidden the 4 totals regions.
shown the 4 Percent regions.
In the false action, I have shown
hidden the 4 percent region
shown the 4 totals region.
The event specification for one these true actions is
Action -> Hide (If I am hiding)
Fire when event is ->True
Selection type -> region
Region -> The region I want to hide/show.
But it does not work! I tried to replicate the issue on apex, by using a small example but could not. Works fine in apex following the same process.
[URL]
I tried to debug by having a display item to show the value when I change the radio button. The values are changing properly. I tried actually, adding a condition filter in the region itself by using the "Value of item/column in expression1 = expression 2" where expression one I tried :P2_RG and expression 2 as P but that just hides the whole region.

What could be the reasons that some queries execute fast when executed on sqlplus on server, whereas the same queries run slower with same input values fed from application screen?
One issue I guess would be bind variable peeking while using application whereas executing from sqlplus is causing hard parsing and thus getting rid of "peeking"
If displaying the data on application screen is taking time after data has been fetched, where I can see this delay?
I understand the elapsed time under 'Fetch' in tkprof will show time taken to fetch from database and not the time taken to be displayed in the application GUI
finally how to set arraysize in jdbc to improve performance by reducing roundtrips?

im still trying to create workcharts into an Excel sheet (see thread "How to create pie chart in Excel sheet"). I could not be able to create pie chart, but I got to create a histogram chart. Now, I wish to customize labels and legend.
The issue is that the data range is made by non-contigouous cells, and some of them are merged. So, I tried to create by hand a pie chart, and this is the code behind:
Sub Macro1()
'
' Macro1 Macro
'
'
Sheets("SUMMARY COSTS 2011-2012-2026").Select
[code]....
how can I implement this code in Forms 10g using OLE2? In details, how does SeriesCollection work?

We have integrated Oracle Access Manager 11gR1 with Oracle Apex 4.1. The OAM-Apex integration is working fine. Now we want an additional header variable to be passed from OAM to the Apex application. This new header variable will be user's sAMAccountName in Active Directory. OAM is integrated with AD and the AD users are successfully able to access the Apex applications.
The three header variables which are configure in OAM right now are:
Header variable name Value
1. OAM_REMOTE_USER $user.userid
2. OAM_REMOTE_USER_EMAIL $user.attr.mail
3. OAM_REMOTE_USER_GROUPS $user.groups
We need an additional header variable as mentioned below:
Header variable name: OAM_SAMACCOUNTNAME
Value: $user.attr.samaccountname
The new header variable was added in the OHS server's dads.conf file like shown below:
=========== dads.conf =============
...
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_GROUPS
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_EMAIL
PlsqlCGIEnvironmentList HTTP_OAM_SAMACCOUNTNAME
But we are not able to read the value of this attribute in the Apex application.On the Apex application, we have a text box which shows the value of this header variable. This textbox is attached with the following stored procedure call to fetch the header variable:
===================
begin
:P1_HEADER_VALUE := owa_util.get_cgi_env( 'HTTP_OAM_SAMACCOUNTNAME' );
end;
The textbox shows the correct value if HTTP_OAM_REMOTE_USER is passed to the get_cgi_env method but does not shows anything when HTTP_OAM_SAMACCOUNTNAME is passed to the same method. if I am missing some configuration to pass the HTTP_OAM_SAMACCOUNTNAME haeder variable from OAM to Apex.

I have multiple application set-up using session sharing within the workspace.Technically all works fine, however it does not play nice with user behaviour.
Example:
Users logs into APP_ID:100. Since he isn't authenticated yet, he provides user/pass and the APP_SESSION is authenticated.
Now if the user switches using to another application (using a link provided in application 100) he gets redirect to APP_ID:101:APP_SESSION all is fine.
The session is already authenticated, the application shares the session and the user gains access to app 101 without having to authenticate again. All's fine!
However users don't behave they way. Instead of using an easy link in the application. They will use their own bookmark or type in the url for app 101 manually. That way the next application is either called with f?p=101:1:[SOME OLD SESSIONID FROM BOOMARK] or f?p=101 (with no further page or session info) In both cases instead of using the already authenticated session apex spawns a new session, which of course isn't authenticated yet thus forcing the user to authenticate and come complaining they have to login again.
Similar behaviour problems exists when the user opens a browser and tries to open both applications in each in a tab next to each other.Both tabs fetch there own initial session id and start writing it to the same cookie each in turn invalidating the other tab's session.These can lead to some fanatic ping pong actions. Thus it's impossible to open 2 applications sharing session in the same browser.
Is there any remedy for these situations?Can apex be as smart as for instance first trying to resume the session stored in the cookie and only if that session is invalid, start a new session?

how to use checkbox item, and trying to get checked options values via application global arrays. So, this may be quite simple question, but I'm completely stuck here...
When I was looking through various threads and guides, I've encountered checkbox corresponding array names like "g_f01" - "g_f50". And so far i saw that these names are derived from item name in generated HTML code, for example:
<input type="checkbox" name="*f10*" value="3" />
And this one stands for array name "g_*f10*".However, when I tried to do the same thing - i receive item name which looks like "*p_v04*", and therefore, I can't figure out, which array name should I choose to adress it properly.
My generated HTML snippet:
<input type="checkbox" id="P6_ANSWER_0" name="*p_v04*" value="3"/>

Each time when I import an application into my workspace in local 10g XE using the APEX 4.2 Application Builder, I get the "ORA-02291, constraint wwv_flows_fk violated..". The application I whant to import was originally exported from [URL]. I found out, that it has to to with wwv_flow_application_install.get_workspace_id in the installation script, which obviously returns NULL and not my current workspace id as I suppose it should. I replaced wwv_flow_application_install.get_workspace_id by '<my worskspace id>' and then the import does work.

I have an application that I'd like to prevent activity in after a certain time of day, say 3pm. Is there any way I can force logout of all current users and then prevent re-login until 9am the next day (short of deleting all of their login credentials and then recreating them the next morning)?

We have developed an application for our clients,planning to deploy it in client server soon. we have plans to support the application in future,so we want to restrict the clients from any modifications. By Doubt is, 'build_status=Run only' alone,cannot protect our application from client developers to edit our application,
Because though we install our application as 'Run Only' at the time of installation in client instance,we can still import the original application and change the type to 'Build and Run Application',and run the new application as 'Build and Run'.(which is not supposed to) we want to make sure,if there is any way we can protect our application from modifications after client side installation.

I'm trying to connect a javascript UI control within my page to an APEX Application Process. The control calls the application process via AJAX and appends a variable number of GET / POST parameters to its URL.What is the best way to obtain these parameters from within the PLSQL procedure of the process? Or is there a better way to connect my javascript AJAX control to the Database behind my APEX app?
