Discoverer Viewer Report with Page Items Slow Performance
I created a report in Discoverer User that has page items and parameters and runs fine (under 3 minutes) in Discoverer User, but when I try and run it in Discoverer Viewer it takes a long time. It took over 70 minutes before manually terminating it. I made a copy of the report and removed the page items and tried to run it again in Discoverer Viewer and now the report runs in under 3 minutes. Any idea why a report with page items would run in Discoverer user fine, but not discoverer viewer?
I am using Oracle Business Intelligence Plus 10g (10.1.2.55.26)
As long as you can access the middle-tier server where Discoverer Viewer is running, you should be able to run and view Discoverer worksheets.
While it is difficult to even start guessing what the problem might be, if the machine you installed Discoverer on has DHCP addressing, you will run into problems.
Thanks

Hello all,
I am using APEX 4.0.3 and I would like to create a report where I could have editable page items within it. My objective was having for instance a variable number with its characteristics displayed in the report and the in one column be able to choose one second from a select list to associate to the first one.
In resume I need to have both a select list in the report, and I need to know how do I access the value of this item in each of this rows.
Thank you,
MikeYou need to loop.
Check out "Referencing Arrays,Referencing Values Within an On Submit Process" sections in following documentation.
This should give you fair idea.
http://download.oracle.com/docs/cd/E10513_01/doc/apirefs.310/e12855/apex_app.htm
For example if you have report with following query
SELECT APEX_ITEM.TEXT(1,column_name) FROM myTable;
and if you have 10 rows in table, then 10 text items will display on your page.
Since we have given the ID (p_idx) as 1, we can refer these text items using G_F01 global array. (If its 2 then G_F02 etc. we can have upto 50 dynamic item on one page)
G_F01.COUNT gives us "number of items"
G_F01(i) gives us value of i ^th^ text item value.
Hope it helps

Bug report: Energy Manager causes slow performance...
Very slow Windows Startup..
Energy Manager's plans and the problem occured using any plan as I remember, and it wasn't an issue with the maximum processor state. I had heavy disk usage, especially access to the Page File, which is what the person in the second link I posted also described. CPU usage was low. The disk usage was seemingly not related to Energy Manager (Chrome was usually the worst), but removing Energy Manager completely resolved the problem. If you would find it helpful. I'm quite confident that even with Maximum Processor state at %100, CPU usage was low when it was slow, and that disk access was the culprit.
previously have use 1.0.0.31 or 32 not sure.

Im using Lenovo Energy Management Driver
1.0.0.28
4.6.2014I actually have the same problem. Sorry to work on a old thread, but...
I've got my Lenovo B50-70 less than 1 month ago, and had switched it to SSD and had set everything up and is working perfectly. However there are a bunch of lenovo programs that came pre-installed. This computer is used mainly for work and I really don't like programs that suddenly pop-up and ask you to do stuff, as it is quite distracting, and with Lenovo Energy Manager being one of them so I removed it. (I did do some research before I remove...)
Everything was fine, until when I try to switch on my wifi (I usually have it off, as I use LAN most of the time)... For the B50-70 there is a airplane button on F7, which allow the user to switch wifi and bluetooth on/off. That button was unresponsive... After some digging it is actually related to the power energy manager being removed. So I've downloaded the latest version from Lenovo and it was working again...
However though, whenever I start my computer it is taking so long to start... And I tried uninstalling the power energy manager and it solved the problem... And I am stuck with either having no wifi on/off ability or a really slow boot, which loses the whole purpose of the SSD. After you enter your username and password it originally takes around 5~10 seconds to login, now it takes over 1 minute.
I have found this other link, which says Lenovo Power Manager having the same problem.
https://forums.lenovo.com/t5/ThinkVantage-Technologies/Bug-report-Power-Manager-causes-slow-performa...
There is a solution, which you can change the registry to switch a function off. I've tried it and it didn't work, which is not surprising as it's a different program.. But I am hoping that Lenovo can provide a similar solution for Lenovo Energy Manager... -

REPORT WITH CHANGING ITEM ON THE SAME COLUMN
Hi to all,
i'm trying to build a report with different item in the same column.
Is that possible in any way using other Oracle technique?
i'm not doing anything specific here, only i would like to know if the following possibility exist or not and how can i let apex render the htmldb_item fields 'dynamically'.
Using this CODE inside a PL/SQL function body returning sql query I obtain the following report content. Such the code of htmldb_item.fields is written, as a field value the HTML_ITEM is not rendered, so only the description of them appear in the report.
Does somebody know some tricks to make it work?
Thanx a lot
1 2 LAST_CALL htmldb_item.date_popup (4, ROWNUM, FLD_VALUE,'dd/mon/yyyy') VALUE
21 1 AGE htmldb_item.text(4,FLD_VALUE,10,10) VALUE
create or replace FUNCTION FNC_GEN_GUI_ITEM(ITEM_TYPE NUMBER) RETURN VARCHAR2 AS
STRHTMLDITEM VARCHAR2(4000);
BEGIN
CASE ITEM_TYPE
WHEN 1 THEN STRHTMLDITEM:=' htmldb_item.text(4,FLD_VALUE,10,10) VALUE ';
WHEN 2 THEN STRHTMLDITEM:=' htmldb_item.date_popup (4, ROWNUM, FLD_VALUE,''dd/mon/yyyy'') VALUE ';
END CASE;
RETURN STRHTMLDITEM;
END FNC_GEN_GUI_ITEM;
MY TABLE AS FOLLOWS:
CREATE TABLE "NEWPROJ"."DINFIELDGUI"
( "ID" NUMBER NOT NULL ENABLE,
"FLD_TYPE" NUMBER,
"FLD_NAME" VARCHAR2(4000 BYTE),
"FLD_VALUE" VARCHAR2(4000 BYTE),
CONSTRAINT "DINFIELDGUI_PK" PRIMARY KEY ("ID"));
Message was edited by:
Marcello NocitoHi to all,
i've solved, is very simple using decode inside the select:
SELECT
ID,
FK_HTMLDB_ITEM, DECODE(FK_HTMLDB_ITEM,1,HTMLDB_ITEM.DATE_POPUP(3,rownum,VAL,'dd-mon-yyyy'),2,HTMLDB_ITEM.TEXT(3,VAL)) VALORE
FROM TESTID
my table is:
CREATE TABLE "DEV"."TESTID"
( "ID" NUMBER NOT NULL ENABLE,
"FK_HTMLDB_ITEM" NUMBER,
"VAL" VARCHAR2(4000 BYTE))

Muse,Page items slow to load - eliminate render blocking java script?
Everything was running smooth until I tried to cut and past new items into master pages. Now I have master page items loading out of sequence and very slowly at that. I went to google's page speed insites and I scored a 72% with a reccomendation to "Eliminate render blocking java script in above fold content" as well as "leverage browser caching"
Well... I have no idea what that means
any idea how I can improve the performance of my page? I've already compressed the images significantly, I don't think that's the problem. Google talks about expirey dates on cache items being too low or non existant causing delays on pages, and setting priority over viewable items. Can I do this in Muse?
you can view the site here
http://batco.businesscatalyst.comI've actually been having the same problem - the interesting thing is that I've only really noticed it in the past several weeks (before, everything loaded fine). Could there have been a change in Muse in the way it's loading scripts that is slowing it down?
Examples:
www.karlchristiankrumpholz.com
www.pawdnerscolorado.com
On the second site, I can't remember if I crunched the images, but on the first one, I used Image Optimizer to crunch down all of the pngs prior to publishing. For reference, I'm publishing both sites via Business Catalyst; one using a free CC account, and one using a paid eCommerce account.
I ran it through Google PageSpeed, and here's what I get:
Eliminate Render-Blocking JavaScript and CSS in above-the-fold Content
Your page has 1 blocking script resources and 5 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
Remove render-blocking JavaScript:http://webfonts.creativecloud.com/bebas-neue:n4:all.js
Optimize CSS Delivery of the following:
http://www.karlchristiankrumpholz.com/StyleSheets/ModuleStyleSheets.css
http://www.karlchristiankrumpholz.com/css/site_global.css?4210242644
http://www.karlchristiankrumpholz.com/css/master_desktop-master.css?4254541493
http://www.karlchristiankrumpholz.com/css/index.css?3941979157
http://webfonts.creativecloud.com/c/c3d3d5/bebas-neue:n4.TGd:N:1/d
Leverage Browser Caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Interestingly, image size doesn't appear to be as much of an issue, according to PageSpeed:
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 30.3KiB (13% reduction).
Losslessly compressing http://www.karlchristiankrumpholz.com/images/headerbackground.png could save 19.1KiB (22% reduction).
Losslessly compressing http://www.karlchristiankrumpholz.com/images/laurel.png could save 4.9KiB (29% reduction).
Losslessly compressing http://www.karlchristiankrumpholz.com/images/rebel_%402x.png could save 4.6KiB (7% reduction).
Losslessly compressing http://www.karlchristiankrumpholz.com/images/karlheader2-u1353.png could save 1,019B (2% reduction).
Losslessly compressing http://www.karlchristiankrumpholz.com/images/arrowmenudown.gif could save 707B (84% reduction). -
Report with entity beans - BIG performance problem
I have several EJBs (CMP entity beans).
I need to build a report using linked EJBs and show this report
to a user (so, updates are not needed - report is only for web page demonstration).
the problem is: such report is generated too slow.
I have ~100 records in table 'TestResult' and ~500 records in table 'TestObject'.
these tables are linked like this:
one testobject <--> many testresults
for each testresult I need to show a line with some info which should be retrieved
from bound EJBs (e.g. testresult-testobject-assigneduser-prioritylevel)
how to optimize such report generation?
I have heard something about session beans with Value Objects.
do I need to use such session beans here?
what is a general solution for generating reports using linked EJBs?
I tried to solve the problem by using DB View, but it didn't help.
I have used 'TestResultView' - info is retrieved fast enough from this view
(several msecs), but displaying this info is still very costly.
please, help!
Oracle 8.1.7,
WebLogic 6.1Hi,
because I have checked the time required to
1) retrieve EJBS (several msec)Let me share some of my views with you.Once you retrieve the EJBS ie ie the collection of remote interface from the finder method the container is firing single "select " query and gets all the primary keys back.
2) cycle through it - get fields and display them
(~4000 msec)Now the cycle of getting the value you are getting the bean from the PooledState to ready state which will get the fields by firing the "select" query (ejbload()). Now in the instance you are invoking the multiple methods and at the end it will remain there in ready till you call the remove which u are not doing so the time out will bring it back to the pooledstate.
And if you are calling the bean very frequently then all the instances will go to the ready state and the activation & passivation will start developing ......
So at the end when the bean moves back to the pooled state after timeout the ejbStore() fires the "update " query!!!!
Let us consider the activation/passivation not appearing for simple understanding !!!!!!!!
So for each iteration you are firing 2 queries to the database.So if you have 500 records then the queries generatted will be 1(select from finder)+2(1 by select(ejbload)+1 by update(ejbStore))*500. So the flow is calling 1001 queries ...Thus quering about 1000 queries will definetly take some time...
So what is the solution????
Any way you dont require to fire the update query as you are just viewing the data...So u can stop calling the ejbStore().
Hence you queries will drop to half.Now how we can do this is by using the BMP.....
The other solution is using the Sessionbean and store the data all 500 records in the Object which can be called across the n/w. This object should implements the Serializable interface and this tech is the Transfer Object feature.....
Hope you find this useful..

Discoverer Viewer Report in Web
Hi,
I had created the report usingOracleBI Discoverer Plus Version 10.1.2.45.46c & able to visualize the report in OracleBI Discoverer Viewer Version 10.1.2.45.46c.
URL fo accessing the report is as:
http://machinename1:7777/discoverer/viewer
If i try to connect to from another machine (machine2) as
http://machinename1:7777/discoverer/viewer
i'm unable to connect & i get the error page can not be displayed.
Is it necessary to have the URL only with domain name as
http://machinename.domainname:portno/discoverer/viewer
I had already installed OWB, Oracle BI etc. If i had to create a domain then i have install all these & need to work from scratch.
Is there any way to access the report across the internet or web.
Plz do provide a solution for this issue.
Thx in AdvanceAs long as you can access the middle-tier server where Discoverer Viewer is running, you should be able to run and view Discoverer worksheets.
While it is difficult to even start guessing what the problem might be, if the machine you installed Discoverer on has DHCP addressing, you will run into problems.

Error (ORA-01403) saveing data form a report with apex_item items
Hi all,
I've a problem saveing data that's inserted into a report which I created using apex_item items. Reproducing the exact issue on apex.oracle.com will take me a lot of time, and I don't know if I really can reproduce this matter... So I hope I can explain my problem clearly enough, here...
The global story of the application is that its an application used for measureing objects. For these objects there are templates, with default properties. When measureing an object, the user must fill in those properties for the object. The report is build dynamicly, becouse each object has different properties and each property could be of an other kind (number, text, list, counter [=number field with add and substract buttons], and date). Depending on the type of the property, the report has to show an other item to fill.
The query for constructing this report is like this:
select defprop.proptyp_id,
apex_item.hidden(41,defprop.id) defprop_id,
defprop.nam,
decode(proptyp.id,
1, apex_item.text(p_idx=>42,p_value=>''||
decode(defprop.srt, 'CONSTANT', (select WRD
from measurement_prop
where defprop_ID = defprop.id
AND measurement_id IN
(SELECT ID
FROM measurement
WHERE OBJ_ID = obj.id
AND DAT IN
(SELECT latest_date
from object_instance
WHERE ID = obj.id)))
||'' ,p_attributes=>'class=case5_num'),
2, apex_item.text(p_idx=>42,p_value=>''||
decode(defprop.srt, 'CONSTANT', (select WRD
from measurement_prop
where defprop_ID = defprop.id
AND measurement_id IN
(SELECT ID
FROM measurement
WHERE OBJ_ID = obj.id
AND DAT IN
(SELECT latest_date
from object_instance
WHERE ID = obj.id)))
||''),
3, apex_item.select_list_from_query(p_idx=>42,p_value=>''||
decode(defprop.srt, 'CONSTANT', (select WRD
from measurement_prop
where defprop_ID = defprop.id
AND measurement_id IN
(SELECT ID
FROM measurement
WHERE OBJ_ID = obj.id
AND DAT IN
(SELECT latest_date
from object_instance
WHERE ID = obj.id)))
||'', p_query=> 'select wrd, id from property_typewrd where proptyp_id = ' || proptyp.id ||' order by vlgnum', p_show_null=> 'NO'),
4, apex_item.text(p_idx=>42,p_value=>''||
decode(defprop.srt, 'CONSTANT', (select WRD
from measurement_prop
where defprop_ID = defprop.id
AND measurement_id IN
(SELECT ID

from default_property defprop,
object_instance obj,
property_type proptyp
where defprop.stdobjver_id = obj.stdobjver_id
and defprop.proptyp_id = proptyp.id
and obj.id = :P2200_ID_INVThis report works fine. Depending on the type of the property it shows a numberic field, text field, selectlist (with right values), counter field or date field.
If the default property is set to a 'CONSTANT' value, the last known value is filled in.
With a javascript I check the numberic field value and achieve the counterfield to add or substract values when 'plus' or 'minus' is clicked.
This javascript is placed in the field 'Execute when Page Loads' in the page properties in APEX. Here is the code:
/*Execute when page loads*/
/*Allow only numbers */
number_elem = $('input[name=f42].case5_num');
number_elem.keypress(function(event) {
if (event.which && (event.which < 46 || event.which > 57 || event.which == 47) && event.keyCode != 8) {
event.preventDefault();
if (event.which == 46 && $(this).val().indexOf('.') != -1) {
event.preventDefault();
//for mouse events, remove any non numeric characters
number_elem.bind('mouseup mousedown mouseleave', function(event) {
this.value = this.value.replace(/[^0-9]/g, '');
/* Subtract Button */
$('a[name="sub_f42"]').click( function() {
number_elem = $(this).siblings('input[name=f42].case5_num');
currVal = number_elem.val();
if ( isNaN( currVal) ){
elemVal = 0;
else {
elemVal = Number(currVal);
if (elemVal > 0)
number_elem.val(elemVal-1);
else
{ elemVal = 0; }
/* Add Button */
$('a[name="add_f02"]').click( function() {
number_elem = $(this).siblings('input[name=f42].case5_num');
currVal = number_elem.val();
if ( isNaN( currVal) ){
elemVal = 0;
else {
elemVal = Number(currVal);
number_elem.val(elemVal+1);
});Those two codes makes my report works fine. So far I'm happy. But now I want the data, which the user fills in the items, to be saved.
So I created a process that should do this for me (it wil run after the user hits a button), here is the code:
declare
v_objmet_id number := 0;
begin
select measurment_seq.nextval
into v_objmet_id
from dual;
insert into measurment
( id
, obj_id
, dat
values
( v_objmet_id
, :P2200_ID_INV
, :P2200_METDAT_INV
/*Loop trough the values (g_f42 holds the value of the property)*/
for i in 1 .. apex_application.g_f42.count loop
/*g_f41 holds the key to the default property*/
if apex_application.g_f41(i) is not null and
apex_application.g_f41(i) > 0 then
insert into measurment_prop
( measrument_id
, defprop_id
, wrd)
values
( v_objmet_id
, apex_application.g_f41(i)
, apex_application.g_f42(i)
end if;
end loop;
end;After running this process, the application branches back to the page, clearing the cache and set some items I use for filtering an other report with their own values.
Both the process and the branche have a 'when button pressed' condition, where the same button is filled in. The branche fires on submit: after processing.
When I hit the button to save the data, I get an error: ORA-01403: no data found
In the debug info I can find there is encountered an unhandeled exception in the process, but I don't know what's going wrong...
I thought it could be something with the date field, I want to save, so I put it in a to_date() with the right format, but I still got the error...
I've also checked if the query which fetches the nextval of the sequence is correct, and it is, no typeing error in the sequence name, or something.
I'm using APEX 4.0.2

Changed some code of the javascript, it directed to the wrong item ID, now its correctMy problem is solved. The error occured when application item g_f41 was accessed, so my application couldn't find the data, the user putted in there. I now pasted this part of the sql, to the other apex_item field, so it became one field and now it works correctly:
select [...]
apex_item.hidden(41,defprop.id) ||
decode(proptyp.id,
1, apex_item.text(p_idx=>42,p_value=>''||
decode(defprop.srt, 'CONSTANT', (select WRD
from measurement_prop
where defprop_ID = defprop.id
AND measurement_id IN
(SELECT ID
FROM measurement
WHERE OBJ_ID = obj.id
AND DAT IN
(SELECT latest_date
from object_instance
WHERE ID = obj.id)))
[... etc ...] -
Very intermittent missing page regions / report rows / page item values
My goals in making this posting are twofold:
1. I'm looking to see if anyone else has experienced this type of issue before.
2. I'm looking for ideas about what can be done to debug such an infrequent bug with serious implications.
Synopsis
I'm having a weird problem where very infrequently I will load a page and I'll notice that one or more page regions, report rows, or page item values are missing. If I reload the page the missing parts appear as they normally should.
By "very infrequently" I would say it happens to me somewhere between 1 in 100 and 1 in 1000 page loads, of course at my last project demonstration in happened twice in 10 minutes to my demo participants. I've attempted to debug this, but most of the techniques I know of involve reloading the page or reposting the form data and (of course) everything looks fine then.
Environment
* This has happened on multiple different pages, under ApEx 3.1 (Linux) and 3.2 (Solaris).
* I believe that so far I've only ever seen this under Firefox 3/3.5 under OSX, but since I do the vast majority of my development with this browser it's not reasonable to conclude that it only happens under Firefox.
Logs
* No application errors during this timeframe.
* Nothing of significance in the database alerts log (just thread notes and log sequences).
* Nothing of significance in the webserver log (just the usual mod_ossl connection errors).
Thanks for your attention,
Jason
Edited by: Jason G on Jul 24, 2009 12:43 PMWell, thanks for reading the post anyway.
While working through some debugging steps I realized that I was populating some of the regions as the page rendered using AJAX -- this would pause the page rendering until the AJAX request returned. I believe that a hanging AJAX call was the likely culprit of the very intermittent symptoms I was seeing.
I moved the AJAX calls to the last region of the page and added a javascript function that "watches the page load" by checking for regions by ID and looking at javascript boolean flags to let me know when the page is fully rendered. If this process takes longer than 5 seconds it notifies the user that something happened and offers to reload the page for them in an effort to fix the issue.
So far, so good -- but it will take a lot of testing to convince me that this case is solved. I hope my documenting this is helpful for others in similar situations.
Good luck,
Jason -
Refresh SQL Report (Submit Page Item)
I want to add a search field in a SQL Report. I have something like this
SELECT * FROM emp
WHERE emp_no LIKE :P1_SEARCH || '%'I want to do the search asynchronous, on keypress. The problem is that a SQL Report doesn't have a "Submit Items:" atribute like a interactive report.
So after i refresh the report:
$a_report($x('P1_REPORT_ID').value,'1','10','100');The report is refreshing (the circle icon on top of the screen) but nothing changes cause the :P1_SEARCH doesn't submits.
How could i submit a page item from JS ?
King Regards,
Cearnau Dan
PS: I'm using APEX 4 and using dynamic actions it's the same like the Javascript call.(still doesn't submits the :P1_SEARCH item)Hi Dan,
I would suggest not to use the undocumented
$a_report($x('P1_REPORT_ID').value,'1','10','100');It's very likely that it will be changed in APEX 4.1

Numeric Dimensions with Page Items
If you have a numeric dimension such as a period number when you select the Page Item 'ALL' and it aggregates the rows it also aggregates any numeric dimension. Can you stop this other than changing the numeric dimension to a character object. ( this effects the sort sequence)
You need to loop.
Check out "Referencing Arrays,Referencing Values Within an On Submit Process" sections in following documentation.
This should give you fair idea.
http://download.oracle.com/docs/cd/E10513_01/doc/apirefs.310/e12855/apex_app.htm
For example if you have report with following query
SELECT APEX_ITEM.TEXT(1,column_name) FROM myTable;
and if you have 10 rows in table, then 10 text items will display on your page.
Since we have given the ID (p_idx) as 1, we can refer these text items using G_F01 global array. (If its 2 then G_F02 etc. we can have upto 50 dynamic item on one page)
G_F01.COUNT gives us "number of items"
G_F01(i) gives us value of i ^th^ text item value.
Hope it helps

Kenny_IHi Kenny_I,
Based on the error message, the issue may be caused by the incorrect configuration of Claims to Windows Token Service (C2WTS). The C2WTS is required because the communication between the web front-end (WFE) and the Reporting Services shared service will
always be Claims authentication.
The domain account used by the Claims to Windows Token Service needs to be granted the following rights through the Local Security Policy:
Act as part of the operating system
Impersonate a client after authentication
Log on as a service
We can find these settings under Administrative Tools > Local Security Policy > Local Policies > User Rights Assignment. And we should add the service account to the local Administrators Groups ahead.
For more information, please see the following links:

Hope this helps.

BUG?: Paginate Doesn't Work with Page Item with Source as Database Column
CREATE TABLE T_PARENT
ID NUMBER NOT NULL
, STAFFID VARCHAR2(20)
, CONSTRAINT PARENT_PK PRIMARY KEY
ID
ENABLE
insert into T_parent values (1, '77258317');
commit;
create table T_child as
select
rownum id
, '77258317' staffid
, dbms_random.string('U', 5) aa
, dbms_random.string('U', 15) ab
, dbms_random.string('U', 3) ac
from dual
connect by level <= 100;
/Form page for T_PARENT.
Classic report:
select id, aa, ab, ac
from t_child
where staffid = :Px_STAFFIDTry and paginate = no data found.
However, if you first submit the page, then paginate, it works as expected.
Reproduced:
http://apex.oracle.com/pls/apex/f?p=54920:57:106342795192226::::P57_ID:1
If I for e.g. use an item with static assignment, it works fine.
Cheers,
Trent
Edited by: trent on Apr 19, 2013 11:59 AM
Also, it works fine when you reference the PK column.Just like with the paginate, the problem may also happens when you change the sort column or direction by clicking on the header.
If the item in the WHERE clause was being set fromt he URL this wouldn't be an issue because it would be saved on the Persisten Session state.
Regarding session state, there are two kinds Temporary or in memory and Persistent. When the page is rendering the item values are only on the Temporary session state. This is why the report renders correctly on page load.
The item value won't go to Persistent session state until the page is submitted. Item values also go to Persistent session when they are passed in the URL, or explicitly set with a computation, etc..
The Session state Dialog can only show the Persisten session state which is saved in DB tables. It's unable to show you the values during page render. For that you need other mechanisms like debug messages.
I think that when you set page item as SQL query and Only when current value session state is null the value must be saved to Persistent session state. If you can examine the value with the Session Dialog then that would confirm that.
Hope this helps.
Thanks
