Custom Tabular form - Session state values disappear

Hi,
I have a custom tabular form page using apex_item and apex_collections. I am using the apex_collection to store the values in memory in order to avoid the data loss in session state. The page is working fine after a validation failure and it shows the values on the second report (as advised for custom tabular forms).
In this, some of the rows have clob value which needs to be edit on a rich text editor. Since apex_item does not provide a solution to have rich text editor, I have to branch to another page on an Edit link for the CLOB data using a modal window. However When I return back from the modal page, the values disappear from session state, and the validation (using htmldb_application.g_fxx arrays) does not take place.
Is there any workaround to overcome this issue?
Apex version: 4.1
Thanks in advance.
Natarajan

Thanks Daniel for your reply.
Actually its an interface with a custom tabular form on page 1 with apex collections and rich text editor on page 2. Since it is not possible to have the rich text editor, I need to have it in another page (I could have it the same page, that is the way I am trying now) however I open the next page as a modal window.
I have a link on the tabular form, so that the clob content is opened in the rich text editor on the next page. After the edit, I update it to the same collection and go back to the tabular form page and refreshes the report. It works fine, but causes trouble to the data entered on the other columns in the custom tabular form.
I have now deviated to another work and put this on a hold. If my explanation is still not clear, I will create the same page in apex.com to simulate the error.
Thanks again.

Custom tabular form error on apex_item id larger than 50

First post :)
I'd like to share a potential bug in apex (3.0.1) or misconfiguration in our application server
When creating a page with a custom tabular form, i've noticed that when i give a column an id over 50 (ex: "apex_item.text(51,salary) salary")
the page will generate errors in the apache.
The apache error log states the parameter F51 as incoming but it contains no value.
Further allong the log states:
"VARIABLES IN FORM NOT IN PROCEDURE: F51"
example report query:
select apex_item.hidden(1,"ID")||apex_item.checkbox(2,"ID") delete_checkbox
,apex_item.text(3,name) name
,apex_item.text(51,salary) salary
from employee;
I've always been under the impression that we could use F01 till F99?
Is there anyone who has encountered this problem before, or are my conclusions wrong?
Looking forward to an answer!
Niko

Hi Niko and Roel
Roel, you are right, I am hitting the 50 columns only limit too. Do you know of any ways to overcome this limit?
This post also describes the problem: Re: column in tabular form
Currently I need to create a tabular form to edit a table with 84 columns.
It sounds ugly, but this is a spreadsheet and the requirement is to get it in Oracle Apex 'as it is' and still, be able to edit it using MRU.
Any ideas?
Thank you very much.

Custom tabular form for multi-row not saving data

Ok, before anyone asks, yes, I did read the how-to:-)
I have a custom tabular form, which I did cause I need to use popups and the popups that you can use in the wizard tabular form does not display the text but rather the value underneath it.
It returns data rather nicely and when I go and update values I can tell it is changing the fields underneath. I put a process in that will display the values in text fields on the form (for one row only) and I see them changing from what is already there and with the proper values.
However, when I do that the data that is displayed then gets reverted back to what it was previous to the update but reports that the process was successful.
I have also tried to insert but that is basically doing the same thing. Can anyone guide me.
SQL to generate the tablular form...
SELECT x.sak_release_db

Florian,
Checkboxes are different from other HTML form items. When you have a text box for example, there's always a value send to the server when submitting. Even if that value is NULL. When you have a checkbox however, you only get the value if the checkbox is checked. It's not posted to the server when it is not checked. That's the general behavior of HTML forms and not specific to Oracle HTML DB.
When working with tabular forms in HTML DB, you can access your form values using the htmldb_application.g_f0x arrays. Now if you have for example 10 rows in your form, then you'll get ten elements in your array for text boxes, select lists, etc. For checkboxes however you'll only get as many elements as you have rows checked. If I read your update and insert code correctly, you're trying to use the checkbox arrays the same way you use the arrays based on other item types. My recommendation would be to use Yes/No select lists instead of checkboxes or at least use select lists initially to get it working and then work on properly processing the checkboxes.
Some general information about working with checkboxes in tabuar forms can be found here:

Hope this helps,

Session state value translation issue

Hello.
New to APEX and not all that web-savvy. Using version 3.1.2.00.02.
Little background:
I have a Select List item, "P1_OPERATOR", working from an LOV of relational operators (=, >, >=, <, <=). I use this item as a string substitute in report queries. This works fine for any reports on the page containing the "P1_OPERATOR" definition itself, "PAGE_1".
Problem:
However, when I attempt to set a session state value for a similar item ("P2_OPERATOR") on "PAGE_2" to the value of P1_OPERATOR using the column link of a report on PAGE_1, the value of P1_OPERATOR does not translate correctly for any values involving a right or left angle bracket (it works only for '=').
Scenario:
Let's say I'm on PAGE_1 and I select >=. The reports on that page display as expected. When I click on the link to PAGE 2, the reports there display "invalid relational operator". When I view session state from PAGE_2, I can see that...
P1_OPERATOR is '>='
P2_OPERATOR is '& gt;=' (space added to get it to display on this post).
So it's trying to use the html value for >= as a literal value.
I can also see that APEX has built the URL for the link page as follows...
(abbreviated) http://...:P2_OPERATOR,P2_DATE:%26gt%3B%3D%2C2009-06-27
If I type in the expected literal URL myself (outside of APEX) as...
(abbreviated) http://...:P2_OPERATOR,P2_DATE:>=,2009-06-27
...or even the expected hex URL (outside of APEX) as...
(abbreviated) http://...:P2_OPERATOR,P2_DATE:%5C%3E%3D%5C%2C2009-06-27
...PAGE_2 shows the expected results.
Is there a way to solve this translation problem? Some workaround I haven't thought of?
Thanks for your help.
Edited by: user11313762 on Jun 29, 2009 2:30 PM

Use an PL/SQL process On Load - Before Header with the following:-
*:P2_OPERATOR := :P1_OPERATOR;*
You'll have to use a hidden item as your condition (having looked at a page debug, any request value will have expired by the time the process will fire).
create a hidden item on page 2 called P2_SET_OP
use Item = value type of condition in your process where exp1 = P2_SET_OP (don't use colon notation here as ITEM has been specified) and exp 2 = Y
You can even reset P2_SET_OP back to null in the same process as you assighn the operator.
*:P2_OPERATOR := :P1_OPERATOR;*
*:P2_SET_OP := NULL;*
set the value of P2_SET_OP in your link as P2_SET_OP:Y

Need help with the session state value items.

I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?

You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Custom Tabular Form addRow function

Hi All
There appears to be a lot of people discussing this on the forum, but so far, I haven't been able to find a solution.
I have a custom tabular form and I need to add and Add Row button to create multiple blank rows without submitting the page. I have previously used a solution devised by Duncs many moons ago, that basically clones a row.
http://djmein.blogspot.co.uk/2007/12/add-delete-row-from-sql-based-tabular.html
Unfortunately, this basic method doesnt work for popup_lov apex items, nor will it increment ID numbers.
Ideally I would like to be able to use the addRow function that is used for a Tabular Form built using the Wizards; however, that function uses a ghost row as described in this forum thread:
"Ghost row" in 4.0 Tabular forms has id pattern f0x_0000
If it were possible to replicate that ghost row in a custom tabular form, then I guess that it would be possible to use the apex addRow function out of the box!?
Before I start re-inventing the wheel, has anone aready done this, or can you point me in the right direction please.
I hope that makes sense :)

Tabular form condition type value of item / column in expression 1

Hi
Question 1
I was wondering if anyone can help with the necessary syntax so that I can set a Condition Type for a column in a Tabular Form.
What I'm trying to do is show or hide a column based on the contents of another column in the same row for instance show column DETAIL or DETAIL_READ_ONLY if column READ_ONLY is set to 'Y'
Value of item / column in expression 1 = #READ_ONLY# or READ_ONLY (alas neither works)
Expression 2 = Y
I can set all the DETAIL or DETAIL_READ_ONLY columns to either hide or show at the same time by
Value of item / column in expression 1 = P100_READ_ONLY (works well but lacks granularity)
Expression 2 = Y
Question 2
Are Tabular Forms such that all fuctionality has to be global, what effects one column must be the same for all
I know that Oracle prefers that developers don't use tabular forms but they are usefull for data visability when setting up related data in the same table.
e.g. surveys, questionnaires etc apps the web was made for
Thanks
Derek

Hi Sandro
Thanks for replying
The problem I have is Tabular Forms
Detail Text Detail Read Only Read only
Event 1a Event 1b Y
Event 2a Event 2b N
Event 3a Event 3b Y
What I want it to look like is
Detail Text Detail Read Only Read only
___________Event 1b__________ Y
Event 2a_____________________ N
___________Event 3b__________ Y
This would mean that the Text Field containing Event 2 could be updated but the Display Only fields containing Event 1 and Event 3 cannot be changed.
The trick is to be able to mix and match data types for the same data because Tabular Forms columns don't have a conditional read only choice.
Sorry about the rudimentary diagram, but its the old 80 / 20 rule =>20 percent functional

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.

Application Items/Session State Values and Page Branching

I have users coming into a specific page in my application, passing in a value on the url that sets the value of an application item, where a validation routine occurs. If their session validates, I want to send them to one page, if it does not, I want to send them to a login error page.
During validation, I am setting the values of several application items so that these values can be saved and used throughout their session. The values appear to be setting correctly. I am concerned that setting the application items may not be limiting these values to a particular session. So, I have also tried setting the setting session state variables with code like:
apex_util.set_session_state ('F203_REQ', vReqID);
I found it curious though when I ran this page, not trying to branch so I could check session state, these values showed up as being application items and I saw nothing under session variables.
The problem I am having is that once validated I don't know how to branch to these other pages. I have tried adding some javascript in the header to force a page submit so that I could use a branch setup on the page. However, when it comes time to evaluate the branches (it's using one of the application item values I set earlier), I'm getting an error that no branch has been provided. Further research suggests the application item values are being cleared on the page submit.
So, (1) I either need to know how to preserve those values on submit so the page branch works or (2) I need to branch to the new page without using a page submit and instead doing that in a some code (assuming submit is clearing application item values). I have not been able to find an example of how to do this in code. If there is a way to do this in code, will the application item or session state variable values be retained? I will need these values to be available to the user throughout their session.
Thanks for the help,
Steve

Steve,
I am concerned that setting the application items may not be limiting these values to a particular session.They are set in the current session only.
It is hard to know what you are doing exactly without seeing it. If you set up an example on apex.oracle.com we could could address one specific question at at time.

Session State Values Only Used After a Page Refresh

We recently moved our application to use Oracle Application Server. I don't know if this is an issue but I thought it might be relevant to my question.
In this application there is report that has a link to another page. This link sets the ID of the company that the subsequent pages use to provide several summarized reports with drill downs. I'll call this the main page.
Users recently started to report that when they drill into the details and use the breadcrumbs to get back to the main page, that page will display the wrong company, one they were viewing recently.
In testing I find that when I click a link to drill down into the details the details page is not for the right company. I check session state and the value of the ID is correct. If I refresh the page I then get the correct drill down page. Some of the drill down reports will pass a page specific ID into each page and others will just reference the ID from the main page. Not sure if this is relevant since the breadcrumbs to go back to the main page would not be able to use every possible page specific ID, my understanding was that once I set the ID in session state on the main page I could rely on it.
Also if I get the wrong details page and click on the breadcrumb to the main page I get the wrong main page (it displays a previously viewed company). Again the session value is correct and a refresh of the page will bring back the right company.
Our systems admin was asked to check if we had WebCache on and she said it was not. Is there something else that could be caching the results of these pages?
Thanks,
Greg

Tabular form default column value bug when using named notation?

Hi,
I am using Application Express 4.0.2.00.07
After exporting and importing an application, the default value of a tabular form column results in an "ORA-00907: missing right parenthesis" error.
My original application uses named notation while calling my function (no problem here):
Report Attributes > Column Attributes > Tabular Form Attributes > Default type = PL/SQL Expression or Function > Default = pkg_customers.some_funtion (*in_param =>* :P15_FK_CUSTOMER_ID).
When I change this in my imported application to ... > Default = pkg_customers.some_funtion (:P15_FK_CUSTOMER_ID) everything works fine again.
Is this a known bug or is there something I do not see?
Regards,
Frederik Van de Velde.

yes it is
p_column_default=> 'calpa_pkg_klanten.fun_sm_betreft_default (in_pk_klant_id => :P9_FK_KLANT_ID)',
p_column_default_type=> 'FUNCTION',
by default it is set exactly the same, but when running the page the tabular form does not render because of the usage of " =>".
thx

Why doesn't a Popup Key LOV (named LOV) in a tabular form not display values in the popup?

I have a tabular form and I'm setting one of the fields to a Popup Key LOV (named LOV). The named LOV is a static LOV. When the popup is displayed there are no values displayed. The same thing happens if I use a Popup LOV (named LOV).
I created a sample application http://apex.oracle.com/pls/apex/f?p=15762:1that shows what happens. When the job field popup is selected, no items are displayed. If I change the item to a Select List (named LOV) it works fine.
Is this a bug?

Hi
I am also getting the same issue. Hope it could be a bug.
Can anyone plz confirm this?
Thanks

Custom Tabular Form with working days by quarter

Hi All, I'm trying to create an application to improve an old excel that some people use in my office. I came across a challenge: create a page when a user can submit for each business day the amount of hours worked, the real problem is that I have to show on the same page 40 business days that need to be dynamic, I mean that there is a "period" table that has a start date and end date, the range between those two MINUS the Saturdays and Sundays should be the amount of COLUMNS that the report show.
create table CT_PERIOD(
PERIOD_ID VARCHAR2(6),
PERIOD_FY VARCHAR2(4),
PERIOD_QUARTER VARCHAR2(1),
PERIOD_START_DATE DATE,
PERIOD_END_DATE DATE,
PERIOD_DAY_COUNT NUMBER,
insert into ct_period values ('1', 'FY14', 'Q1', to_date('01-JUN-2013', 'DD-MON-YYYY'), to_date('25-AUG-2013', 'DD-MON-YYYY'), 56);
commit;
I searched in the web for some example of this with no luck, if somebody did something like this or knows where I can see an example that would be great!
Thanks!

Hi guys,
I'm having exactly the same problem, I need a tabular form with days as columns to add actual working hours for each day as for each row ( task)
