APEX_UTIL.PREPARE_URL does not work across workspaces?

We are running ApEx 4.1.1 on Oracle 11g.
I am trying to call an application in another workspace and am using APEX_UTIL.PREPARE_URL in a hidden item and then a button with REDIRECT TO URL using javascript:popUp2 which uses the hidden item (the returned value of the PREPARE_URL. The code works fine if I am in the same workspace and a checksum is returned:
APEX_UTIL.PREPARE_URL('f?p=9002:2:&SESSION.::NO::P2_CALLING_APP_ID,P2_CALLING_APP_NAME:&APP_ID.,&G_APP_NAME.&c=STU_WS','SESSION');
returns:
f?p=9002:2:1400894538262901::NO::P2_CALLING_APP_ID,P2_CALLING_APP_NAME:9001,FRD_MASTER_BANSECR&c=STU_WS&cs=3190FB9A8CC967E5B3CED03460DF6F291
I can press the button and app 9002 opens in a new window.
When I try the same code in an application in another workspace, no checksum is returned:
APEX_UTIL.PREPARE_URL('f?p=9002:2:&SESSION.::NO::P2_CALLING_APP_ID,P2_CALLING_APP_NAME:&APP_ID.,&G_APP_NAME.&c=STU_WS','SESSION');
returns:
f?p=9002:2:8288147979401::NO::P2_CALLING_APP_ID,P2_CALLING_APP_NAME:112,Testing_Template&c=STU_WS
and I get the error:
Error Session state protection violation: This may be caused by manual alteration of a URL containing a checksum or by using a link with an incorrect or missing checksum.
I have also tried it without the workspace '&c=STU_WS' and explicitly passing the parameters, but no checksum is returned.
APEX_UTIL.PREPARE_URL(p_url => 'f?p=9002:2:&SESSION.::NO::P2_CALLING_APP_ID,P2_CALLING_APP_NAME:&APP_ID.,&G_APP_NAME.',p_checksum_type => 'SESSION')
If I do not try to pass any parameters, no checksum is produced, but the button successfully opens app 9002 in a new window:
APEX_UTIL.PREPARE_URL('f?p=9002:4:&SESSION.::NO::&c=STU_WS','SESSION');
returns:
f?p=9002:4:8288147979401::NO:::&c=STU_WS
Again, the above code successfully opens app 9002 in a new window. In fact, when not passing parameters to app 9002, I would not seem to need to use PREPARE_URL.
BUT. I do need to pass the calling app id and the calling app name to app 9002, because 9002 looks up information about the calling app. Since, I must pass parameters, I must use PREPARE_URL, and it does not seem to work when you call it for an app in a different workspace.
Given all of the above, I have found a kludge. I call PREPARE_URL using the APP_ID of the current app and then replace that APP_ID with 9002.
replace(APEX_UTIL.PREPARE_URL('f?p=&APP_ID.:2:&SESSION.::NO::P2_CALLING_APP_ID,P2_CALLING_APP_NAME:&APP_ID.,&G_APP_NAME.&c=STU_WS','SESSION'),
'f?p=&APP_ID.:2','f?p=9002:2')
returns:
f?p=9002:2:8288147979401::NO::P2_CALLING_APP_ID,P2_CALLING_APP_NAME:112,Testing_Template&c=STU_WS&cs=33B2BB2ECFE3555198CE3325CCF9F67B8
And the button opens app 9002 just fine.
Is there anyway to get PREPARE_URL to work with apps in another workspace? What am I missing? Is there a better way than the kludge I came up with?
A little more information: my app 9002 is a help & info for ApEx DBAs and Developers. It is my attempt at code reuse. Calls to 9002 are in a master template. I can continually update and change the help in 9002 without having to update the apps that call it.
Thanks for your help,
Chris

Apex_util.prepare_url from PL/SQL (outside APEX)

Hello there,

Apex_Util.Prepare_URL Question due to Apex Util Advisor msg

Hi,
I have the following code in an SQL statement within an IRR:
APEX_UTIL.PREPARE_URL( p_url => 'f?p=' || v('APP_ID') || ':398:'||v('APP_SESSION')||'::NO:398:P398_IDOBJ:||VIMG_SEARCH.IDOBJ:', p_checksum_type => 'SESSION') FullImg,
And it works as expected. However when i run the Apex Util Advisor I get the following:
Attribute Region Source (Identifies the source of the region, reference Region Source Type)
Check V Function used in SQL Statements
Category Performance
Message Contains V/NV/DV function call in SQL statement (can be a performance problem).
Do I need to worry about this ? or should I change the syntaxt within the APEX_UTIL.PREPARE_URL parameters ?
Thank you
Daniel

In SQL (and PL/SQL blocks within APEX) the bind variable notation should be used:
APEX_UTIL.PREPARE_URL( p_url => 'f?p=' || :APP_ID || ':398:'||:APP_SESSION||'::NO:398:P398_IDOBJ:||VIMG_SEARCH.IDOBJ:', p_checksum_type => 'SESSION') FullImg,The <tt>v(...)</tt> notation is for use in database PL/SQL program units called from APEX.

APEX_UTIL.PREPARE_URL with checksum

Hi all,
sorry to bring up this topic up again.
I was trying to do what was discussed in the following thread, but it just couldn't work for me.
APEX_UTIL.PREPARE_URL 0- cecksum parameter
The link in my email did not have the checksum parameter though i have run it over the APEX_UTIL.prepare_url function
I verify this using the toad debugger.
and I use the following sql to test as well
select apex_util.prepare_url('f?p=137:99::5:NO:5:P5_REQUESTSEQ:2010100246',null,3) from dualit only return that string back without any checksum parameter.
Am I doing this wrongly?
Appreciate any input.
Thanks.
-Joel

Hi Jari,
Should i have session id because the link will be used by other people whom is the recipient of the email?
I was following the steps in the other thread I mentioned.
So if the link you want them to use is f?p=100:1:::NO:RP:P1_X,P1_Y:abc,def and your new public page is 2, send them this link instead:f?p=100:2::1:NO:RP:P1_X,P1_Y:abc,def.Without the SSP, the redirection and joining existing session are working. So I guess order of the parameter in the URL is correct.
Thanks

Trouble getting apex_util.prepare_url to produce checksum

Session State Protection is enabled in both apps & Page attribute "Page access protection" is set to "Arguments Must have Checksum"
Does not give checksum...
http://apex.oracle.com/pls/apex/f?p=34780:3
I even went into SSP and had it enabled for all page items and pages and still doesn't make a difference.
Select 'x', APEX_UTIL.PREPARE_URL ('f?p='||:APP_ID || ':1::' || :APP_SESSION || '::::P1_EMPNO:' ) employee_link from dual;
Different app Same Query... Provices checksum

Any Ideas?

APEX_UTIL.PREPARE_URL cannot produce checksum

Hi, Guys:
I tried to use APEX to generate checksum for url, but it does not work, no checksum is generated. I was confused. Culd anyone tell me what is the problem? here is my code:
DECLARE
l_url varchar2(2000);
BEGIN
:P1_TF_CHECKSUM:= APEX_UTIL.PREPARE_URL('f?p='||:APP_ID||':12:'||:APP_SESSION||'::NO::P12_ACE_ID:xyz', p_checksum_type => 'SESSION');
END;You can find my application on apex.oracle.com:
workspace: LIAPEXTEST
acc:[email protected]
pwd:lxus2000
app_ID: 44976
Thanks!

Hi,
My understanding is that the checksum will only be generated if there is some sort of session state protection enabled, on the items you are trying to set through the URL. (Probably if the page has some sort of protection as well)
For example, the text item you have on page 1 has the security setting: "Checksum required - session level".
So I copied your page process, and attempted to set that page item in the process - now you will see the checksum generated.
On the original process (currently disabled), for which you are setting an item that doesn't exist, and thus has no session state protection, therefore no checksum is needed.

Apex_util.prepare_url within a select statement

I think that the problem is that the function apex_util.prepare_url is executed building the "q" variable, not during query execution. (you have to try to quote it ...)
I often use the "Query from function".
There a couple of things that helps me:
- I always put in the page an item PXX_SHOW_SQL(checkbox) visible only to administrator (a user setting in my application...).
Before the "return q" put a htp.p(q) if this Item is not null. So you can see the actual SQL (often helps reformattig the output with SqlDeveloper)
- I'm became crasy tring to quote complex query ... Now I write the query code in a TABLE
Example AUXSQL(APP_ID number,APP_PAGE number, PRG number, sql VARCHAR2(4000))
More "PRG" if more than 4000 chars. (I start in this way, but someone use CBLOB ...)
I find this very usefully!!

Interactive Report Performance With Conditional Link

Apex 3.2
I have a interactive report.
The underlying sql would return 127000 rows
The sql is
select
lde.ods_system,
lde.ldekey,
msg.sendersystem,
msg.messagetype,
msg.messageversion,
msg.msgseqnumber,
msg.alternatekey,
msg.crudmarker,
msg.clrbookdate,
msg.clrbookresult,
lower('udf_'||msg.messagetype) button,
lde.ldekey||'.'||msg.alternatekey||'.'||msg.msgseqnumber udm_key
from
clr_esbmessageheader msg,
clr_adm_systemmessage adm,
udm_lde lde
where
adm.ldeid = lde.ldeid and
msg.sendersystem = adm.system and
msg.messagetype = adm.messagetype and
msg.messageversion = adm.messageversion and
msg.receiversystem = 'SCIPS'
order by msg.clrbookdate desc
This report only takes 1 second to display.
I need to add a conditional link to another page, so I used
case
when lower('udf_'||msg.messagetype) = 'udf_distreceipt' then
'<a class="type" href="' || apex_util.prepare_url('f?p='||:APP_ID||':52:'||:APP_SESSION||'::'||:DEBUG||':RIR'||':IR_MSG_KEY,P52_PG:'|| lde.ldekey||'.'|| msg.alternatekey ||'.'|| msg.msgseqnumber ||','|| 50, null, 'SESSION') || '"title="Go to udf_distreceipt Report">udf_distreceipt</a>'
else 'no link' end table_link
The sql seems to be ok, because the report accepted it, but selecting the new column and saving the report takes forever (over 2 mins)
Now the report takes over 2 minutes to run and I still need to add more conditions.
Have I coded the link incorrectly ?
Gus

Hi Gus,
Are you wanting to put the link in the query for a specific reason?
I had to do a similar thing in the past and just completed the column link section for the column.
Why not just have the following in the query:
case
when lower('udf_'||msg.messagetype) = 'udf_distreceipt' then
udf_distreceipt
else null END table_link
Then do the linking using column link section:
You would specify your link text as #TABLE_LINK# which should then be conditionally displayed due to the case statement, then add in all the page item and values to pass across using a normal link column.
Thanks

You said:
"I was able to debug the code in SQL Developer." Does this mean that you:
ran the code, got results
then set indep_degree to 'Y' on a row in your database
ran the code again and saw the results you are looking for?
If true, your code is working and should operate the same in APEX.
So if your code is working, we need to understand what processes are running on the form and when they are firing.

Interactive Report Download and Session State Protection

I have created an Interactive Report in an APEX application that I have enabled
session state protection for. The issue I am having is with the "Download"
functionality of the interactive report to a .csv file.
The URL created by selecting Download from the drop down (javascript:gReport.controls.download();)
is built or constructed without a checksum thus causing the error below.
Error
No checksum was provided to show processing for a page that
requires a checksum when one or more request, clear cache, or argument
values are passed as parameters.
The anchor tag containing the URL (/f?p=app_id:page:session_id:CSV:) is contained within
<div id="apexir_CONTROL_PANEL_DROP" class="drop_panel
clearfix" style="">
Running the following: Application Express 3.1.0.00.32 on Oracle Database 10g Enterprise Edition Release 10.2.0.3.0
Is there a way to add a checksum to this? OR does anyone have any ideas on how to work around this?
Edited by: Bryce Tuohy on Feb 26, 2009 10:08 AM

WORKAROUND:
1.) Create hidden ITEM on page (I named it P23_PREPARED_CSV_DOWNLOAD_URL).
Enter the following for the ITEM
as the SOURCE_TYPE : PL/SQL Function Body
as the SOURCE: return apex_util.prepare_url('f?p=&APP_ID.:&APP_PAGE_ID.:&APP_SESSION.:CSV:')
2.) Create BUTTON that executes javascript to open POPUP window with this url.
a.) Create Button and enter
<a href="javascript:popupURL('&P23_PREPARED_CSV_DOWNLOAD_URL.')">Download and Save to CSV file</a>as the "Text Label/Alt"
Originally had custom code for javascript POPUP and this is not needed .... just use the APEX javascript function.

Interactive report, conditional display of column link

Hello,
We have requirement to disable editing in case that status of field is 1 (1=Closed).
Is there any way to disable it on interactive report.
case when status=1 column link should be disabled (not visible) in order to prevent future edits on payroll.
SELECT payroll_no, status
FROM hr_payroll
ORDER BY payroll_no DESC;
I tried link below, but it's not working in my case.

CASE WHEN status = 'ACTIVE' then
<a href="f?p=&APP_ID.:60:&SESSION.::&DEBUG.::P60_EMPLOYEE_ID:'||employee_id||'"> <img src="#WORKSPACE_IMAGES#deactivate_button.png"></a>' ELSE NULL END deactivate_employee,
from
EMPLOYEES
What exactly is the error you get? What HTML is showing in the HTML source?
Just by looking at this I would say you need to remove the "/" in front of the f?p
Keep in mind this way could cause problems if you start to use checksum, then you might want to look into using APEX_UTIL.PREPARE_URL to create your URL.

How can I pass paramters to next page with session protection on?

Hi, guys:
I encounter a problem of session protection problem. In a report page I set up a column of "map" link, so I can pass several parameters extracted from the same row to the new page where I can show map. I was using javascript popup2, and it worked well.
javascript:popUp2('f?p=&APP_ID.:3006:&SESSION.::&DEBUG.::P3006_H_OFFENDER_NAME,P3006_H_OFFENDER_ID,P3006_H_ADDRESS_LATITUDE,P3006_H_ADDRESS_LONGITUDE,P3006_H_PHYSICAL_LATITUDE,P3006_H_PHYSICAL_LONGITUDE,P3006_H_ADDRESS,P3006_H_PHYSICAL_ADDRESS:#Offender Name#,#Offender ID#,#Address Latitude#,#Address Longitude#,#Physical Latitude#,#Physical Longitude#,#Address#,#Physical Address#','650','450');However, I am required to set all of pages, items with session protection now. after that I got problem as:
Attempt to save item P3006_H_OFFENDER_NAME in session state during show processing, item has Internal Only protection.
Contact your application administrator.
So I changed it as redirect a page in application, and try to pass less parameters and query other parameters, but I got the similar problem:
Attempt to save item P3006_H_OFFENDER_ID in session state during show processing, item has Internal Only protection.
Contact your application administrator.
I notice most of solutions would be turning the session protection as unrestricted for these items, but I am not allowed to do this. Is there any way that I can pass parameters from a row in a report while session protection is on?
Thanks a lot!
Sam

I can quickly show you what I've done to solve for this:
First, create a PL/SQL Anonymous block, application level process of type "On Demand" Here is an example of what I'm using - I named the process is SIMPLE_SSP (name is important later)
declare
l_url varchar2(1000);
s_url varchar2(2000);
begin
l_url := wwv_flow.g_x01; -- the apex name is g_x01 - note the key in the key value we pass later in javascript
s_url := apex_util.prepare_url(p_url => l_url,p_checksum_type => 'SESSION'); -- and here's where we get checksum
htp.p(s_url); -- and here's where we return it
end;
Next, I create a javascript function that can be called in the link
function redir_ssp(p1,p2,p3) {
var param1 = p1;
var param2 = p2;
var param3 = p3;
// notice when creating our Ajax object we reference the Application process by name
var ajaxReq = new htmldb_Get(null, &APP_ID., 'APPLICATION_PROCESS=SIMPLE_SSP', 0);
var sURL = 'f?p=&APP_ID.:4:&SESSION.::::P4_PARAM1,P4_PARAM2,P4_PARAM3:'+param1+','+param2+','+param3;
// notice the 'x01' literal mirrors the built in apex var we used above. x01, x02, x03 ... etc match their counterparts.
// you can use many parameters as long as you deal with them in the proc the same way
ajaxReq.addParam('x01',sURL);
var retURL = ajaxReq.get(); // and the htp.p is passed into the ajax get which is then returned in the retURL
//alert(retURL); // for debug
window.location.href = retURL; //this is the redirect.
Finally in the link
<a href="#" onclick="Javascript:redir_ssp(p1,p2,p3)">link text</a>
This can be easily altered to use in a pop up.

How to remove hyperlink in Reports Region

How to remove hyperlink in a Report region (Based on some filter condition)
Example : In Report Region, I am getting value as 10, 20, 30, 0, 44, 55, 0
In the above value, I need to remove the hyperlink for 0 values.
Can anyone help me to resolve this issue.
Thanks in advance.

Balaji S

If you want a link column for values other than 0 and a blank for those with 0 then the best way to do this is to use a case or a decode to return a LINK image or text to a hidden column; I usually return the Edit icon only. You can then use the 'column link' region on a different column to create a link in the usual way and set the Link Text to the hidden column (e.g. #EDIT# in the example below). If you have set the target page to require a Checksum this will then be added without having to code it into your sql. E.g.
SELECT some_columns,
CASE WHEN numcol != 0 THEN '<img src="#IMAGE_PREFIX#e2.gif" alt="">'
ELSE null
END "EDIT"
FROM your_tableIf you want the same column value, but those of 0 to not have a link and those other than 0 to have a link then you need to code the link into your sql. e.g.
SELECT some_columns,
DECODE (numcol,0,numcol,'<a href="f?p=&APP_ID.:11:&SESSION.::&DEBUG.:11::">'||numcol||'</a>') "EDIT"
FROM your_table# = your URL e.g f?p=&APP_ID.:11:&SESSION.::&DEBUG.:11::
If you require a checksum on the link you need to add the apex_util.prepare_url function to the URL.
