Tabular Form Values
Hi everyone,
I currently developed a tabular form to track time against activities. For each week my hours are submitted into the database. I currently have a multi row update that inserts my hours into the designated table. I would like to know how to keep my hours in the database but at the same time set my values on the screen to '0.0' when I re-click into my week. Can anyone help me with this issue?\
Thanks
Ryan
Hello Tealord,
>> I'm using Application Express 3.2.0.00.27. Due to existing applications the business will not upgrade at this time to 4.
The behavior you describe, and the problems that go with it, is the standard behavior of pre-V4.0 versions. It was very neatly resolved in APEX 4.0 but according to your post, you can’t upgrade, although the reason is not clear to me.
This is not a simple problem to solve. In my book, in the chapter dedicated to Tabular Forms, there is a description of a possible solution, and the demo application that accompanies the book includes a demo page of the solution. Unfortunately, this is not a simple (or short) solution so I can’t display it in the forum. If it’s important, you should gain access to the book.
Regards,
Arie.

How to set a default tabular form value?
I am trying to set a default value for a tabular form.
In Tabular Form Element:
========================
Display as: Date Picker
Formet: Date Picker (DD-MON-RR)
Default Type: Item (application or page item name)
Default P2_DATE
My item P2_DATE is set as:
==========================
Date Picker (DD-MON-RR)
However when I try to add a row with a default date I get this error:
report error:
ORA-01790: expression must have same datatype as corresponding expression
Any ideas?
Regards,
Pawel.Sorry for spamming but found a solution:
which was to change the type into PL/SQL Expression like so:
to_date(:P301_PROJECT_XFR_DATE,'DD/MM/YYYY')
This is the format I used in P2_DATE...

Cannot Update Tabular form Values Error in mru internal routine: ORA-20001:
i have created some master detail records through a manual tabular form. Iam getting the following error when i tried to updated the values through another inbuilt tabular form....
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "9067F4C5EF14529F831CB42B5567C288", item checksum = "07865E78639EB6477FB5DFB8B02EA047".,Hi
Hopefully my response to your Error in mru internal routine: ORA-20001: no data found in tabular form thread will help. In this thread's example, there is no error message that displays the column names required, but the principle would be the same: Make sure that all fields drawn from the table are included as editable or hidden columns on the report (so that there is one instance of each field shown with a tick in the Edit column on the report's Report Attributes page).

Unable to pick tabular form value....
selecT NVL(SUM(QUANTITY1),0) from RM_LOCATION1 where LOCATION1 = :P3_LOCATION1;+
where location1 is column of my tabular form...
apex doesn't picks these value (i.e :P3_LOCATION1)
as apex treat it as an array... (:P3_LOCATION1)
can any one help how can I make my these query run...Hi Shirish!
I don't know exactly what your trying to achieve. Obviously a custom validation (pl/sql returning error text).
Does your report contain several different departments or only rows for one department?
Without knowing your layout and demands I fear I cannot help any more.
If your report contains only one department and several rows adding for the total commission you could try:
DECLARE
vsum NUMBER;
vsumcheck NUMBER;
BEGIN
APEX_COLLECTION.CREATE_OR_TRUNCATE_COLLECTION( p_collection_name => 'VALIDATE');
FOR j IN 1..APEX_APPLICATION.G_F02.count
LOOP
APEX_COLLECTION.ADD_MEMBER(
p_collection_name => 'VALIDATE',
p_c001 => APEX_APPLICATION.G_F04(j)
END LOOP;
begin
select sum(to_number(c001)) into vsum FROM apex_collections a
WHERE a.collection_name = 'VALIDATE';
exception when invalid_number then
return 'Attention! The Commission must be numeric!';
end;
IF vsum > 1000 THEN
RETURN 'The commission cannot be higher than 1000 for a department! <br>
Please correct your input!';
END IF;
END;Otherwise you should declare your variable x as number:
DECLARE
l_error VARCHAR2 (4000);
x number(10);
BEGIN
FOR i IN 1 .. apex_application.g_f02.COUNT
LOOP
select sum(nvl(QUANTITY1,0)) INTO x from RM_LOCATION1 where LOCATION1 = apex_application.g_f04(i);
IF x > 1000
THEN
l_error :=
l_error
|| '
|| 'Row '
|| i
|| ': Commission can not be higher '
|| ' than 2000 for department '
|| apex_application.g_f08 (i)
|| ' Employee: '
|| apex_application.g_f03 (i)
|| ' Requested value: '
|| apex_application.g_f07 (i);
return l_error;
END IF;
END LOOP;
END;I hope I could help you at least a little!
Good luck,
Seb

How to refresh page after selecting value from LOV item , in a tabular form
Hi ,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, couple of issues here.
1.
2nd item(column) in tabular form, that LoV should get populated based user's selection value in first item LoV. So how do i refer to the value, that user selected in first item's LoV? I will have to use this reference in LoV query of my 2nd item ( on this tabular form)
2.
How can we refresh the page, when user selectes value in first item ( from LoV). As this is a tabular form, here item type is Select List, we dont have an option to pick item type as Select List with Submit. So problem is that when user selects value for item 1, refresh does not happen and item 2 LoV does not get populated as per user's selection in item 1.
Please help here. Would be really appreciated.
Thanks and Regards,
Rave.Thanks Ben and Dan for your responses.
Ben, your solution helped me with refresh of page, as page got submitted.
This answers to my 2nd question. However, I still need to know first question, which basically is, how do i refer to the value, that user selected in first item LoV.
Issue is, I selected the value in first item LoV, it got submitted and page fot refreshed. But after page refresh, first item LoV loses its value that I had selected last time. It does not retain the selected value after refresh.
I have an unconditional process, that on every submit(refresh) of page, I set my items with their corresponding values. But problem is what do i mention there to refer to this item.
I looked in view source of my page, this item is referred as f03.
So i used "apex_application.g_f03", to set this item to its value, in my uncoditional submit process. But it did not work. I tried to refer this item as "f03" in this unconditional submit process. But still it did not help, the selected item loses its value after page refresh(submit).
Any help here would be really appreciated. Please suggest how do we refer to this item's selected value.
Thanks and Regards,
Ravi. -
Enable/Disable item Based Value from Select in Tabular Form
Hi Guys
I want to Disable text field in Tabular form, Based on the Select List Item Value.
Let's Say
I'm having one select lista and text box in each record in tabular form.
Select List having 2 items ... Add Text(return value 1) and No Text(return value 2)
if value =1 then i want to enable text box , so user can enter value.
if value=2 then text box won't allow to add text or will become disalbe.
Please Help
ThanksHi,
You can do this by using a small java script
<script language="JavaScript" type="text/javascript">
<!--
function FldEnableDisable(pThis)
if (pThis == 50)
$x('P2_TEXT').disabled=true;}
else
{ $x('P2_TEXT').disabled=false; }
//-->
</script>Here P2_Text is the text box whose value I am enabling or disabling based on the selected value from a List box. On The list box I have onChange="javascript:FldEnableDisable(this.value)" ( You can specify this under HTML Form Element Attributes)
Thanks,

How to use Default value in a column in Tabular form in insertion or upda
Hello,
I am trying to use Default values so that user need not have to enter data, but when I select default type and put a default value, I see an error message, if I try to add a new row.
How can I use a default value in a Column in a Tabular Form?
Gouri
Edited by: user1046395 on Apr 3, 2009 9:58 AMGouri,
You can just simply edit to each column's report attribute. For example,
To set default date,
Default Type: PL/SQL Expression of Function
Default: sysdate
To set default text,
Default Type: PL/SQL Expression of Function
Default: *'CLERK'*
If you still have an error, what is the error message?

How to use Ajax Get Multiple Values in Tabular form?
Hi All-
I am trying to use AJAX to get multiple values in tabular form by using Denes Kubicek's example in the following link -
http://apex.oracle.com/pls/otn/f?p=31517:239:9172467565606::NO:::
Basically, I want to use the drop down list to populate rest of the values on the form.
I have created the example(Ajax Get Multiple Values, application 54522) on Oracle site -
http://apex.oracle.com/pls/apex/f?p=4550:1:0:::::
Workspace: iConnect
login: demo
password: demo
I was able to duplicate his example on page 1 (home page).
However, I want to use system generate tabular form to finish this example, and was not able to populate the data correctly.
Page 2 (method 2) is the one that I am having trouble to populate the column values. When I checked application item values in Session, and the values seems to be populated correctly.
This is what I have done on this page:
1. Create an Application Process On Demand - Set_Multi_Items_Tabular2:
DECLARE
v_subject my_book_store.subject%TYPE;
v_price my_book_store.price%TYPE;
v_author my_book_store.author%TYPE;
v_qty NUMBER;
CURSOR cur_c
IS
SELECT subject, price, author, 1 qty
FROM my_book_store
WHERE book_id = :temporary_application_item2;
BEGIN
FOR c IN cur_c
LOOP
v_subject := c.subject;
v_price := c.price;
v_author := c.author;
v_qty := c.qty;
END LOOP;
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn ('<body>');
HTP.prn ('<desc>this xml genericly sets multiple items</desc>');
HTP.prn ('<item id="f04_' || :t_rownum || '">' || v_subject || '</item>');
HTP.prn ('<item id="f05_' || :t_rownum || '">' || v_price || '</item>');
HTP.prn ('<item id="f06_' || :t_rownum || '">' || v_author || '</item>');
HTP.prn ('<item id="f07_' || :t_rownum || '">' || v_qty || '</item>');
HTP.prn ('</body>');
END;
2. Create two application items - TEMPORARY_APPLICATION_ITEM2, T_ROWNUM2
3. Put the following in the Page Header:
<script language="JavaScript" type="text/javascript">
function f_set_multi_items_tabular2(pValue, pRow){
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=Set_Multi_Items_Tabular2',0);
if(pValue){
get.add('TEMPORARY_APPLICATION_ITEM2',pValue)
get.add('T_ROWNUM2',pRow)
}else{
get.add('TEMPORARY_APPLICATION_ITEM2','null')
gReturn = get.get('XML');
if(gReturn){
var l_Count = gReturn.getElementsByTagName("item").length;
for(var i = 0;i<l_Count;i++){
var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
var l_ID = l_Opt_Xml.getAttribute('id');
var l_El = html_GetElement(l_ID);
if(l_Opt_Xml.firstChild){
var l_Value = l_Opt_Xml.firstChild.nodeValue;
}else{
var l_Value = '';
if(l_El){
if(l_El.tagName == 'INPUT'){
l_El.value = l_Value;
}else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
l_El.parentNode.innerHTML = l_Value;
l_El.parentNode.id = l_ID;
}else{
l_El.innerHTML = l_Value;
get = null;
</script>
Add the follwing to the end of the above JavaScript:
<script language="JavaScript" type="text/javascript">
function setLOV(filter, list2)
var s = filter.id;
var item = s.substring(3,8);
var field2 = list2 + item;
f_set_multi_items_tabular2(filter, field2);
4. Tabular form query:
select
"BOOK_ID",
"BOOK",
"SUBJECT",
"PRICE",
"AUTHOR",
"QTY",
"BOOK_ID" BOOK_ID_DISPLAY
from "#OWNER#"."MY_BOOK_STORE"
5. In Book_ID_DISPLAY column attribute:
Add the following code to element attributes: onchange="javascript:f_set_multi_items_tabular2(this.value,'#ROWNUM#');"
Changed to -> onchange="javascript:setLOV(this,'f03');"
Now, T_ROWNUM2 returns value as f03_0001. But, TEMPORARY_APPLICATION_ITEM2 returns as [object HTMLSelectElement]...
Please help me to see how I can populate the data with this tabular form format. Thanks a lot in advanced!!!
Ling
Updated code in Red..Ling
Lets start with looking at what the javascript code is doing.
function f_set_multi_items_tabular(pValue, pRow){
/*This will initiate the url for the demand process to run*/
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=Set_Multi_Items_Tabular',0);
if(pValue){
/*If there is an value than submit item name with value*/
get.add('TEMPORARY_APPLICATION_ITEM',pValue)
get.add('T_ROWNUM',pRow)
}else{
/*Else set the item TEMPORARY_APPLICATION_ITEM to null*/
get.add('TEMPORARY_APPLICATION_ITEM','null')
/*Submit the url and te returned document is of type XML*/
gReturn = get.get('XML');
if(gReturn){
/*There is something returned*/
var l_Count = gReturn.getElementsByTagName("item").length;
/*For all elements of the tag item*/
for(var i = 0;i<l_Count;i++){
/*Get the item out of the XML*/
var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
/*Get the id of the item*/
var l_ID = l_Opt_Xml.getAttribute('id');
/*Get the element in the original page with the same id as
**the item we have in the XML produced by the ondemand process
var l_El = html_GetElement(l_ID);
/*Now get the value of the item form the XML*/
if(l_Opt_Xml.firstChild){
var l_Value = l_Opt_Xml.firstChild.nodeValue;
}else{
/*There is no value*/
var l_Value = '';
if(l_El){
/*There is an element with the same id as the item we are processing*/
if(l_El.tagName == 'INPUT'){
/*The element is an input item just set the value*/
l_El.value = l_Value;
}else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
/*If it is a span elment and has the class grabber
**Then set the innerHTML of the parent to the value
**and the id of the parent to the id
l_El.parentNode.innerHTML = l_Value;
l_El.parentNode.id = l_ID;
}else{
/*Else set the value as innerHTML*/
l_El.innerHTML = l_Value;
get = null;
Now where it went wrong in your initial post
The XML that was returned by your XML process would be something like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_1">CSS Mastery</item>
<item id="f03_1">22</item>
<item id="f04_1">Andy Budd</item>
<item id="f05_1">1</item>
</body>
When you don't use apex_item to create your tabular form a item in the table will look like
<input id="f02_0001" type="text" value="CSS Mastery" maxlength="2000" size="16" name="f05" autocomplete="off">
Notice the id's f02_1 and f02_0001 don't match.
So to make it work the XML would have to look like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_0001">CSS Mastery</item>
<item id="f03_0001">22</item>
<item id="f04_0001">Andy Budd</item>
<item id="f05_0001">1</item>
</body>
To do that simply use lpad in the ondemand process like
HTP.prn ('<item id="f02_' || lpad(:t_rownum,4,'0') || '">' || v_subject || '</item>');
HTP.prn ('<item id="f03_' || lpad(:t_rownum,4,'0') || '">' || v_price || '</item>');
HTP.prn ('<item id="f04_' || lpad(:t_rownum,4,'0') || '">' || v_author || '</item>');
HTP.prn ('<item id="f05_' || lpad(:t_rownum,4,'0') || '">' || v_qty || '</item>');
Keep in mind that the above is based on your original post and #ROWNUM# not being lpadded with zero's.

Re-enable column values in tabular form before submit
Hi,
I am using Apex 4.1. I have a tabular form. I created a dynamic action to disable some of the columns on page load.
It works fine and I am able to add new rows. But when I click submit, all the column values are null and it is throwing validation error.
I need to enable all the columns before submit. I invoked a javascript to enable all the fields, but still i get the validation error.
I also tried creating dynamic action to enable the values but still I get the validation error becuase the values are all null.
Please help me to resolve this issue.
Thanks
SRPer HTML standards, disabled items are not submitted. Therefore if they are disabled at the point of submit, their corresponding session state values will be null (as you discovered). Apex validates against what is is session state, not against what is on your screen, so since the values didn't get submitted (per standards for HTML disabled items) that's why Apex thinks they are null.
Before submit, re-enable the items/columns and it should work fine.
Edit: Sorry, looks like you are doing this already. But are you doing it in the right order?
How I have done it is:
1. Change the save/apply changes button (whatever is doing the submit) to call a URL.
2. Make the URL call javascript, such as:
javascript:formSave('SAVE');
3. Put a javascript function on your region or page (hypothetical example):
<script type="text/javascript">
function formSave(pRequest)
{ //Put all checking and processing prior to form save here.
var vRequest="SAVE"; //default value taken from orig. "apply changes" button
if(pRequest)
vRequest=pRequest;
enableAllCells(gMaintActionCol); //Put whatever code you have to re-enable your tabular form items here, must fire before apex.submit.
//Do the save
apex.submit(vRequest);

How to set a column value in a tabular form via button
Hi All,
I am using Apex 3.0.1. And to create the form I am using the APEX interface tool
I have tabular updateable report. In the same page I have a LOV field where I can choose some possible results.
I want to have a button so I can select a value in the LOV, take this value and populate the column value to the LOV value for all rows in the tabular form.
The LOV and the buttons are done.. to update the column I tried creating a pl/sql that is executed when the button is pressed and has the following update in a loop for each element:
begin
for i in 1..APEX_APPLICATION.g_f01.count loop
APEX_APPLICATION.G_F02(i) := :P1_MY_LOV_VALUE;
end loop;
commit;
end;
When I press the button, the page refreshes but nothing happens. I don't see any changes in the Values for the column I am trying to update
ThanksHi user477501,
If you are doing this after a SUBMIT, then try updating your data table instead of the g_f02 array. When you page is re-rendered, it should re-query your data table.
If you do not want to submit the page, then try your hand at JavaScript.
A good reference for this is Mike Hichwa's article at:
http://www.oracle.com/technology/oramag/oracle/06-nov/o66browser.html
Be sure to download the example application, it is very helpful.
I hope this helps.

Passing Session Values to the Tabular Form Element of a Report Column
Hello,
I'm running application express version 2.0 with a 10.2.0.2.0 database on a 32 bit windows box. I'm trying to figure out sneaky a way to pass the &APP_PAGE_ID., #APP_PAGE_ID# or V('APP_PAGE_ID'); as an element attribute of a Report Tabular Form Element set to display as a Select List (named LOV).
It seems that whatever option I choose, the Element Attributes field will only render the literal value of what I have entered. This is part of the solution but I would like to find a way to pass the current page id.
What I'm trying to do is utilize the ONCHANGE attribute to redirect to a report page in my application when the value from a Select List (named LOV) is selected.
I could work around this by creating my own table output with PL/SQL and HTP.P commands but would really be interested in finding out if I can use the reporting structures which are already available through Application Express.
Any ideas?
Thanks.
Justin.Thanks for the response Earl. To clarify this is what I've done and what I hope to achieve:
I currently have a LOV for my application that identifies a number of database report types: DB Options, DB Parameters, DB Version, and so on.
I have an application express report being generated for the databases I'm monitoring and it displays as follows:
- HOST -- DBTYPE -------- DBNAME - DBREPORTS
=====================================
- SVR 1 - Oracle 9.2.0.1 - DEV -------- [LOV HERE]
- SVR 2 - Oracle 9.2.0.7 - TST --------- [LOV HERE]
I am displaying the LOV on my report the the options under the reports attribute tab in my application builder. I insert my LOV select list by editing the DBREPORTS column and set the "Display As:" option under Tabular Form Element to "Select List (named LOV)"; I have also added my LOV to the "Named LOV" option under List of Values.
So far this achieves everything I would expect and works quite well (a select list with my report types appears in my monitor report for each DB that is returned).
What I'm interested in doing now is opening a DBREPORT for a given database by simply choosing the report type from my LOV. I can set the "Element Attributes" option under Tabular Form Element to execute a javascript call for any valid event (in my case I'm using ONCHANGE).
My only issue is that I cannot find a way to pass any session values from my page to my Element Attribute. If, in the Element Attributes field I enter:
onchange="alert(this.value);" //my dialogue box will display the value of my current selection when I choose a report type.
What I'd love to be able to do is something like:
onchange="alert('&APP_PAGE_ID.');" //so my current page id is written to the element.
Unfortunately, only my literal text seems to be rendered. Rather than having my dialogue come back with my page number, say 75, I receive the literal value &APP_PAGE_ID.
Notwithstanding any quote issues, I've tried to dump a test html attribute to my source html by entering any of the following in the Element Attributes field:
test=&APP_PAGE_ID.
test=#APP_PAGE_ID#
and as a shot in the dark knowing that I'm not using PL/SQL:
test=V('APP_PAGE_ID');
In every case when I view source I see the literal value of what was entered in the Element Attributes field (ie "test=&APP_PAGE_ID." instead of "test=75").
What makes things a little more frustrating is that I can drop &APP_PAGE_ID. into the Column Heading field (ex My Heading &APP_PAGE_ID.), it renders as I would expect; "My Heading 75". If we could find a solution to this, I could see a number of slick uses for this type of functionality.
Hope this helps,
Thanks.

Sum the values of a text field in a tabular form using JavaScript
Hi Folks.
OK, I put my hands up. I don't know Java script but I'm picking up the basics and I WANT to learn.
Here's my situation.
I have a tabular form which has lots of Standard Report Columns and ONE text field.
I want to sum the values entered in the text field, real time, using Java Script without the need to have a round trip to the database.
I'm guessing this will involve some kind of loop. Once I have that SUM figure I will store it in a hidden item and it will be used for validation when the user submits the form.
If anyone can give me a simple Java Script to do this, or point me in the direction of one, I'd be very grateful.
Many thanks.
Dogfighter.Hi Arie.
Thanks for the link.
That's a great start,
What I've got working so far is the following...
<script type="text/javascript">
function f_calculate_delta(p_this,p_rownum)
var amt = $x(p_this).value;
alert (amt);
var display_item_to_set = 'f08_'+ p_rownum
$x(display_item_to_set).innerHTML = amt
</script>
This is working fine.
Where I'm stuck at the moment is how I can 'get' the value of another cell in the same row. They have all been set up using the APEX_ITEM API with their own unique IDs.
I will continue looking but if you could give me a steer, that would be great.
Many thanks
Simon
PS. APEX 3.1
PPS. Trying to get the value of another row using...
var display_item_to_get = 'f04_'+ p_rownum
var expected_amt = $x(display_item_to_get).value
PPPS. Also tried...
var display_item_to_get = 'f04_'+ p_rownum
var expected_amt = $v(display_item_to_get)
and
var display_item_to_get = 'f04_'+ p_rownum
var expected_amt = $v(display_item_to_get).value
None of which are working at the moment.

Using select list as default value in tabular form.
Hi,
I am using Application Express 4.1.0.00.32. I have two questions that are related.
I have a Select item *'P1_SELECT'* and a tabular form My Items.
Question 1. The My Items tabular form col1 Attributes are set Display As Text Field, and the Tabular Form Attributes are set Default Type = item(application or page item name), Default = P1_SELECT. I have checked the session state value is set on P1_SELECT ie. Fred. What I need to know is, why, when adding a row to the tabular form My Items does col1 not display 'Fred' as the default value from the select item P1_SELECT? I can change col1 of the Tabular form to be Display as Text (save state) and this will work. However that leads me on to:
Question 2. After adding say 3 rows to the form, I then change the select P1_SELECT value to Bob and Bob is now set in session state on the P1_SELECT item, but when I again add row to the form the value Fred is still the value not Bob. It seems that the tabular form keeps the default value as Fred and not Bob. How can I get this to look or work like:
col1_
Fred
Fred
Fred
Bob
Your help is needed.
Thanks.Howard (DBA in Training) wrote:
Do you submit the page or set the value after changing the selection? If not, the display value seems to be Bob but the working value is still Fred. That's what you are seeing right? In the "Settings" section, what do you have for "Page Action when Value Changed". I've been using "Redirect and Set Value" because I was staying on the same page after the selection.
Additional info which might be helpful (or NOT). ====================
NOTE: I am just a novice's novice with APEX and I had much agony with Select Lists. It was challenging to have the Select List value displayed because there seem to be so many different sources of the Select List value, namely:
1) the current value in the session state
2) the value you can specify in "Source value or expression" in the "Source" section of the Select List item
3) the value you can specify in the "Post Calculation Compution" in the "Source" section of the Select List item
4) the value you can specify in the "Default value" of the "Default" section of the Select List item
[Now, if I've misdescribed any of these, remember, this is from a novice's perspective.]
It's like putting a clock (back) together. Get any of the pieces wrong and it will probably not work right.
I had an addiitonal challenge in that I wanted the same Select List displayed on multiple pages and for the currently selected value (from the former page) to already be set on the new page when it was displayed. What fun!
To see what I did here: http://apex.oracle.com/pls/apex/f?p=43250:101 login Dever/Ima9Dever
Remember, I'm doing many things you will likely not need to do. I iniitalized the Select List for the first time it displayed. I copied the Select List value from old page to new page by storing it in an application item F217_SYS_NIC_NM.
Best wishes,
HowardHi Howard,
You don't have submit the page for just setting one item's session state. you can use a Dynamic Action OR use Page Items to Submit property if available (this is available in various places such as sql region,chart region etc)
In context to this question you don't have to do any of those..just see my example above

Issue with setting a default value to a Tabular Form field
Hi -
I'm running into an issue setting the default value of a tabular form column. I'm trying to set the default value to the row number (#rownum#). This used to work in previous versions, but now it's returning 0. Is there a was to set this value in the default value attribute of the field with a substitution string?
Thank you in advance for help!Share with us what worked in previous versions.

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
DerekHi 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
