Pass value beetween pages in session state

Hi,
I'm getting mad to find out how on the main "sample application" can be passed value from P11_CUSTOMER_ID field to P12_CUSTOMER_NAME field using session !
Can anyone explain me ! No process are submitted on 11 pages !
Thanks,
Ivan

I'm assuming your talking about version 2.2, that is what I am using, I don't know if it changed in 3.0 but probably not.
Anyways if you look at Page 12 there is a computation "P12_CUSTOMER_NAME" that is an SQL Query...
select cust_first_name || ' ' || cust_last_name from demo_customers where customer_id = :P11_CUSTOMER_ID

Pass values between pages

Hello experts!
I am trying to pass value between two pages without page submit.
I set item value from first page to session state by dynamic action. Then I am trying to pass this value to second page, I use button which redirects to second page and sets item value on second page with value from first page.
But approach this does not woks as I expected. The value from the first page is not passed to the second page when I click on button. Value is passed to the second page only if I:
1. set some value to item on first page (e.g. XX);
2. click on button which redirects to the second page;
3. get back to first page;
4. set some new value to the item (e.g. YY);
5. click on button;
6. then the first value from session state is passed to sthe econd page (value XX)
Could anybody tell me where I make a mistake, or what is wrong in my solution?

<input type="button" value="Button1"onclick="apex.navigation.redirect('f?p=9027:3:11397156385140::NO:RP,3:P3_ITEM1:');" id="P2_BUTTON1" />No value substituted for <tt>&P2_ITEM1.</tt> in the URL.
Why do you want to navigate between these pages without a page submit? As APEX has to render page 3 anyway, why not submit and branch?

List of values population based on session state

Firstly, sorry if this is not too clear or just stupid, im new to this.
What I am trying to do is create a list of values on a page that goes to a lookup table and returns description of the code entered.
so far so good
however the tricky bit is that the codes meen different things when applied to different objects.
Now I have got a variable in the session state for the page that can id the object type as G or H namly P39_DISPLAY
Can you do something like ...
IF :P39_DISPLAY = 'G' THEN
select lookup_code||' - '||meaning d, lookup_code r from ip_lookups
where lookup_type = 'PRC'
and upper(enabled) = 'YES'
and start_date_active <= sysdate
and nvl(end_date_active, sysdate+1) >= sysdate
ELSE
select lookup_code||' - '||meaning d, lookup_code r from ip_lookups
where lookup_type = 'RRC'
and upper(enabled) = 'YES'
and start_date_active <= sysdate
and nvl(end_date_active, sysdate+1) >= sysdate
END IF;
I have tried this but getting ORA errors all over the place
Any ideas?

very true, but it is only my third post ;)
I have a table with
val1 val2 va3 val4
I'm using a select list to populate val4
value 4 is a two digit code
00-->99
the meanings of the codes are dependant on the object type. the object type value code is passed from another page into this page.
As far as the table is concerned the object type is irrelivent because its just looking for a code.
However the users require a description in order to use the right code.
So I'm using the variable to pull back the discription of the code based on object type.
I'm giving your idea a bash, created two LOVs. I will test to see if the condition statements stop database entry, I think it might.

How to pass values between pages?

Hi
Anybody know how you pass values like ids between pages using buttons?
Cheers

Hi
Why do you want to do this? You can access values from other pages so if you are on page 2 and there is an item on page 1 called P1_ID you can simply assign it to an item on page 2 by typing in P1_ID in the source value for your page 2 item.
Or you could reference it direct in your pl/sql process by typing &P1_ID. (note the fullstop)
If you did want to pass a value using a button you can do so by clicking on the button name in then scroll down to the section called optional URL redirect.
set target is a - to page in this application
then select the page you want the button to send you to
then click the flashlight icon next to set these items
you can then select the page item you want to send the value to and the page item you are getting the value from.

Passing values to OnDemandProcess from Select Statement on Reports Page

I think I'm just missing some of the proper syntax, Can somebody please help me.
As I've come to understand this process of passing the values,
I recognize it as (3) steps.
1. Referencing the "javascript" in the Select Statement of the Reports Page.
2. Including the "javascript" in the Page Header region.
3. Defining the Process as an OnDemand Application Process.
My problem is:
a. I can't seem to get the Value passed to the Application Process.
b. I don't know how to reference the Value passed once I get it passed.
Here's what I've got done so far:
1. (The Select Statement)
   onClick="javascript:ORDER_CONNECT_SEQUENCE('||ID||')
{code}
2. (The javascript)
{code}
function ORDER_CONNECT_SEQUENCE('+ID+')
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ORDER_CONNECT_SEQUENCE',0);
get.add('+ID+');
gReturn = get.get('+ID+');
{code}
3. (The Application Process)
{code}
   BEGIN
   Select '+ID+' into THIS_CIRCUIT from dual;
{code}
I Know that the Application Process is being referenced and that the OnClick routine is working properly,
because if I plug a Value into the Application Process, instead of using '+ID+',
Then I get all of my desired results.
Any help you can give me here is greatly appreciated.
Thanks- Gary

Dimitri, Thanks for your efforts here, but its still not working for me.
Here's what I understand from your suggestions:
1. (changes to the javascipt)
   a. replace function ORDER_CONNECT_SEQUENCE('+ID+')
       with
       function ORDER_CONNECT_SEQUENCE(pId)
   b. replace get.add('+ID+')
       with
       get.addParam('x01',pId)
   c. replace getReturn = get.get('+ID+')
      with
      getReturn = get.get()
      get = null2. (chages to the Application Process)
   a. add l_value varchar2(4000) to my list of declarations
   b. add l_value := wwv_flow.g_x01 below the begin statement
   c. I guess then I would reference the l_value like this:
       Select l_value into THIS_CIRCUIT from dual* Also, You didn't mention any changes in my Select statement in the Reports region of the page.
FYI.
onClick="javascript:ORDER_CONNECT_SEQUENCE('||ID||')
{code}
The 'ID' which I'm referencing here is an ID from the table which I'm querying.
Am I misunderstanding you somewhere?
Thanks- gary

B1out - B1isql - Pass value of query to insert statement.

Experts,
Perhaps it is because it is late and I am very tired, but I feel as though I am overlooking some obvious solution to the following scenario.
I have created a scenario that is making a SQL Call to a database, and I need to pass the values from that query to a table in a B1 DB.
I am using an outbound channel of B1, and the B1isql type.
here is my issue,
I know that I can pass the value of atom0 JDBC:JOBID to my Field tag.
However, the insert statement uses the tag attribute value="" to pass the values to the DB.
<Table id="invoicesource" keylist="jobid" task="A" del="">
<Field id="JOBID" value="" wrapchar="False"><xsl:value-of select="jdbc:JOBID"/></Field>
</Table>
I'd like to be able to pass the <value-of select= />, into the value="" attribute instead.
Any insight would be greatly appreciated.
warmest regards,
Lucas Fischer

I used standard SQL out instead, since it was for custom DB object, and not SAP B1 table, issue resolved.

Open and pass value to page 2 from page 1 using region button

Good day,
I created 2 pages. I have created a text item called p_employeeid in page 1 and a region button with button action redirect to page 2. When i click the button i can open page 2 but i cannot filter the records that pertains only to p_employeeid. my source for page 2 is select * from test_tbl where employeeid = :p_employeeid.
Help would really be appreciated. thank you.
Mon

hi trent,
i created a branch as well. on submit after processing target type page in this application, page 2 and set this item p2_employeeid and value for this item &p1_employeeid. i did not select any in condition type but selected the button i created submit in the when button pressed. the action of my submit button is submit page.
below is the apex url using button only without branches: only the value of p2_employeeid is not included in the url
http://172.16.10.10:8080/apex/f?p=103:2:872957668524402::NO:2:P2_EMPLOYEEID:
this is with branching: no p2_empoyeeid nor the valu
http://172.16.10.10:8080/apex/f?p=103:2:872957668524402::NO:::
i notice that using the branching even p2_employeeid is not submitted whereas in the button ihave th p2_employeeid but no item value.
I have googling and trying out samples but all i see are table columns with the edit icon. I have not seen example with text box with button calling another page. :(
thank you for the assistance, if you can think of any other suggestion i would be willing to try them out.

Row fetching, session state, multi-page processing of 1 row - problems

I'm building an application that's updating a couple of tables via an updateable view and an instead-of trigger. That portion of it works OK, EXCEPT for the problems that I'm having with the APEX end.
I've got 3 pages; the first page reads the row in via the automated row fetch and has, say columns 1-20.
Page 2 has, say, columns 20-40 and page 3 has the remainder.
I have the row fetch set up conditionally so that it only executes the first time that page 1 is displayed. All the columns are set as Database Columns.
It seems that if I fill in fields on page 1, move to page 2, and back to page 1, the contents of the fields on page 1 are destroyed unless I set their 'Source used' to 'Only when the current value in session state is null'.
Furthermore, upon update (which is on page 3, via an automated row update), the only columns that get updated are those that exist on page 3. The column values from the other pages no longer exist.
Does navigation to another page not retain the session-state of database-column items?
Am I better off just writing my own processes to perform the updates?
Any other suggestions?
Frank

Hello Frank,
>>I have the row fetch set up conditionally so
that it only executes the first time that page 1 is
displayed …
It seems that if I fill in fields on page 1, moveto page 2, and back to page 1, the contents of the
fields on page 1 are destroyed unless I set their
'Source used' to 'Only when the current value in
session state is null'.
It seems that the first sentence is not consistent
with the second one. The only reason the values are
destroyed, as you call it, is that the ARF is running
again. What condition are you using on your ARF?
In any case, the right way to deal with it is to
change the source used to "Only …", as I understand
you already did.
Hi Arie,
I set an item after the first ARF. I then have the ARF set to execute conditionally based on the presence of that item. (I also display a success message on the ARF, so I know that the ARF is only occurring once). I move to subsequent pages by submitting the current pages.
>>Does navigation to another page not retain the
session-state of database-column items?
Navigating to another page does retain the session state values.
It's depends on what you mean by navigating.
Submitting the page set/update session state.
Redirect without submitting the page will not
set/update the session state.
>>Furthermore, upon update (which is on page 3,
via an automated row update), the only columns that
get updated are those that exist on page 3. The
column values from the other pages no longer
exist.
Automatic DML is working only with the current page
items. You can't use it to insert/update other page
items, even if they are in session state. However, in
your case, it's not the Automatic DML performing the
actual updates, but your triggers. Are your triggers
relying on session state values?
I think this statement 'Automatic DML is working only with the current page
items.' answers my question. My trigger is working on session state values. It's an 'instead-of' trigger, so I was letting the automatic DML perform the 'update' on the view, while allowing the trigger to do the actual update of several tables that the view joins by referring to their :NEW. values in the trigger. Since the DML occurs on my last page, those were the only session state values that my trigger ultimately saw.
>>Am I better off just writing my own processes to
perform the updates?
I believe the correct way is to submit the page and
then branch to the next one. Submitting the page will
save all your items in session state, and allow these
items to be available for page 3 DML.
Regards,
Arie.I'm doing that already - all the values do appear to be in session sate, except only the items that are on the last page actually make it to the automatic DML update, which seems to agree with your previous statement.
I suppose I could write my own process to perform the update, as the values are available in session state.
Thanks,
Frank

Use session state values to set column value during insert/update

I am building an APEX 4.2 application that uses the canned Data Loading control to upload csv data to a table. I have modified the 'Select Data Source' page of the workflow and it now contains three LOV's that the user selects values from. The selected values are stored in Session State. As I'm new to APEX, I do not know how to reference Session State objects in the context of the Data Loading workflow so that the appropriate columns are set with the correct values. My assumption is that the columns that are apart of the insert statement reside in a collection somewhere. I just don't know how to loop through the collection, determine the correct column, and then set that column's value equal to the corresponding LOV value in Session State.

Scott,
This is in version 2.2.1 and there are no caching features available.
The application does require login.
I'm playing around with the APP_UNIQUE_PAGE_ID right now but I am finding that even in the builder if I edit the attributes of a report column and then try to edit another column it will bring up the last column I edited. Even if I use the record navigation buttons next to the Apply Changes button it will keep bringing me the same page over and over unless I constantly refresh the pages.

4.2 select list on mobile page not setting session state

Hi,
Like I've done dozens of times in the past, I created a Select list that submits on change, and I expected session state to be updated accordingly.
I tried this on a mobile page but session state is not updated for the item.
Has anyone else experienced this?
Scott

Hi Scott,
is it possible that you are hitting bug# 14680379 - PAGE SUBMIT ACTIONS DO NOT WORK FOR LONGER MOBILE SELECT LISTS, WHEN DEFINED TO FIRE WHEN THE SELECT LIST VALUE CHANGES
on our Known Issues List http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-42-known-issues-1863578.html ?
Is your select list selection displayed as native control or as popup? Can you create a test case on apex.oracle.com?
Thanks

Can't Set Session State from the Login Page

I have a dilema. On the standard login page I enter values in 2 fields namely, CAMPUS (Select List) and USERNAME (text field).
After clicking on the login button I want to navigate to PAGE 1 and use the values of CAMPUS and USERNAME to filter data. I have created two APPLICATION Level items (A_USERNAME,A_CAMPUS) to which I assign the values of USERNAME and CAMPUS in two AFTER SUBMIT computations on the login page.
When I arrive on PAGE 1 the session state values of A_USERNAME,A_CAMPUS are still both null therefore the query returns null. It seems that the login process does not issue a SUBMIT for session state to be saved. How do I save the values in session state on login?
In the Login PROCESS, can I specify the Page 1 items to be set and the values to set them in a URL somewhere? Is it here?
wwv_flow_custom_auth_std.login(
P_UNAME => :P101_USERNAME,
P_PASSWORD => :P101_PASSWORD,
P_SESSION_ID => v('APP_SESSION'),
P_FLOW_PAGE => :APP_ID||':1' <<========here?
If so what is the correct syntax?
If I revisit the login page a second time, a submit is issued and the values are set in session state.
Anyone got any ideas??
I tried creating a standard position button which issues a submit but this didn't work either.
regards
Paul J Platt

Unfortunately your solution is causing problems with retrieving cookies that I try to get for the campus and username during a "Before Header Process" as well. The cookies are normally set on an "After Submit" process. When I return to the login page I get
Error ERR-1029 Unable to store session info. session=10760914996048113736 item=8561939526127479
ORA-02291: integrity constraint (FLOWS_010600.WWV_FLOW_DATA_FK) violated - parent key not found
But if I turn the cookies off, it seems to work OK.

NEWBIE: Submit Page to set session state

I have a form that displays various items to include Popup LOVs (dynamic; based on session variables). If the user displays a page, the session state is not yet set so the Popup LOVs don't function correctly (until the user presses the Apply Changes button to submit the page). Can I automatically submit the page or set session state for those items used in the LOVs on page load? Note that I'm not too familiar with the use of javascript. I'm using Application Express version 2.0

Yes, I discovered that! Thanks for responding, though. I basically run a process (PL/SQL) under page rendering section that looks like:
begin
htmldb_util.set_session_state('P10_MACHINE_TYPE','&P10_MACHINE_TYPE.');
end;
Thanks!

Pass value between JSP pages

I would like to pass values between pages.
I don't want showing up on the url. Ex: some.jsp?param=value
I don't feel it's safe.
It's not coming from form either....
How can I hide the value and pass it to next page?
I want to pass the value when the user click on a hyperlink
Thanks In Advance.

Client side information is never safe no matter what you do. If the values don't end up in the url, they are always present SOMEWHERE in the html content.
If you don't want the values to end up in the url, rework the page so it DOES do a post form submit. You could turn the hyperlink into a javascript call that submits the form for you.

Query referencing session state not consistently returning data

Hi,
I have a form that summarizes expense data by category for employees, per fiscal year, fiscal period, and project.
Clicking on a button next to a particular category takes the user to a new page that should display the detail of those expenses, based on expense_code.
The expense_code is passed via URL to the second page, and the query region for the detail has the following source:
select exp_code, JRNL_ID_NO, DESCRIPTION, REFERENCE, CUR_PER_TRAN, CUM_YTD
from fgspec_ac where exp_code between :P118_EXPENSE_CODE_FROM and :P118_EXPENSE_CODE_TO and project=:P114_PROJECT and fis_year=:P114_FIS_YEAR and fis_period=:P114_FIS_PERIOD
:P118_EXPENSE_CODE_FROM and :P118_EXPENSE_CODE_TO are passed via URL, and the :P114_% fields reference data on the initial form.
The problem is that when I click on the button to bring up the detail for the first time, the query returns no rows. If I return to the original form and click on the button a second time, the query the displays the required data. This behavior is consistent, regardless of expense category, fiscal period, etc. The first time I try to access detail, no records returned, but the second time, it works.
I have used the 'SESSION' link to debug and view the session state in each case, and the results are IDENTICAL whether the query returns data or not. That is, all 5 variables contain the exact same data.
Do you know what I might be doing wrong?
Thanks,
Michelle

Hi guys,
Thanks very much for your replies. In fact, I have tried both methods. Yes, I am navigating from page 114 to 118, and passing values to page 118 from page 114 (ie: P114_PROJECT passes to P118_PROJECT, etc...). In my query, I have tried referencing both, with the same results.
When checking values in session state (by using the 'SESSION' link), values from page 114 are available in both cases (when the query returns rows and when it does not). It is very strange behavior.
I have been developing with HTMLDB for over a year now, and never seen anything like it!!! I will try loading this on HTMLDB.oracle.com, and see if it replicates, and if so, maybe you can have a look...............
Thanks!
Michelle

Report Print Attributes and Session State Protection

Hi all,
I have a report (old style Apex report, not an IR) that I would like to have a Print option, producing a PDF output.
The report is on a page that takes a number of arguments and uses the page security option "Arguments require checksum".
When I turn on the Enable Report Printing option in the report, the Print link appears at the bottom of the report. However, clicking Print leads to the following message:
"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."
Disabling Session State Protection for that page makes the report link work, but I would prefer not to do that.
How do I get the built-in report print option to generate the required checksum?
I'm using Apex 4.0.2.00.07, by the way.
Alex

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.
