Processing mutliple records on multiple pages in a tabular form

I'm a newbie to Apex (4.0). I have a tabular form displaying 500 rows records in multiple pages. The row selector is selected by defaulted ie. all rows have been checked. Upon unselecting items in multiple page, the Multi Row Delete (Post Processing Request) only deletes the records selected on the page. It seems like the ROW SELECTOR does not keep track of the checkboxes on other pages. Any thoughts on how to solve this would be helpful.
Thank you.
Ed.

Sybrand,
Thanks for the response. So in that case, how would I approach the following requirement:
Tabular form that displays 500 records each in multiple pages. The Row Selector column is selected by default. The user will uncheck certain rows in certain pages. I would like to perform a Multi Row Delete for alll the records that were selected.
Thanks,
Ed.

Page process throwing No data found error when deleting tabular form item

Hi guys,
I am trying to run a page process just before the Tabular form's MRU process and it's throwing a no data found error. Here is my code:
BEGIN
 for i in 1..apex_application.g_f02.count LOOP
 IF apex_application.g_f01(i) is not null THEN
 UPDATE STOCK
 SET PRODUCT_QUANTITY = PRODUCT_QUANTITY+apex_application.g_f08(i)
 WHERE site_id = :P21_SITE_ID and product_id = apex_application.g_f02(i);
 COMMIT;
 END IF;
 END LOOP;
END;Here f01 is the checkbox column and the if-statement is causing the problem because if I get rid of the update statement (leaving just the commit) then it still throws the error.
When I click on a checkbox and hit delete button which fires off both this process and then MRU I get the no data found error.
Would be grateful if someone could shed some light on this. Many thanks.

You are iterating on the f02 and checking for f01 not null. That is wrong usage of the the checkbox item. Please see these links . especially the OnSubmit Process examples.

>
Note that check boxes displayed using APEX_ITEM.CHECKBOX will only contain values in the APEX_APPLICATION arrays for those rows which are checked. Unlike other items (TEXT, TEXTAREA, and DATE_POPUP) which can contain an entry in the corresponding APEX_APPLICATION array for every row submitted, a check box will only have an entry in the APEX_APPLICATION array if it is selected.

ORA-06502 on "Help Text" region when changing pages on a tabular form

Hello everybody,
We are developing an application on Apex 4.1.0.00.32. This application have some pages with tabular forms and these pages uses a page zero as template. In this page zero, we have added two sidebar regions: a list region to navigate on the application and a help text to describe how to use our application.
The problem occurs when the tabular split the records into pages (since it has more records that it can show on a single page). When the user clicks to change to another page, Apex raises an ORA-06502: PL/SQL: numeric or value error as described below:
Erro ao renderizar a região "Ajuda". ORA-06502: PL/SQL: erro: erro de conversão de caractere em número numérico ou de valor

Obs: Our database is in Brazilian Portuguese, so I guess it will be hard for some people to understand the first two lines! :)
We have tried to change the pagination style of the tabular form and change the region model of the help text but the problem still happens.
Does anyone an ideia about what this may be?
Thanks in advance!

I am getting the exact same message, to the line number, also in APEX 4.1.0.0.32.

Insert a new record in the middle of a tabular form

Hi,
I have a tabular form.
Pressing "Add Row" button opens a new, empty row at the bottom of the page or - if I use pagination - jumps to the page with the last record and creates a new record there.
Is it possible to open a new line in the middle of the page ?
I mean: if I have 25 records, I am on the first page (records 1-10) and the cursor is in a field of the second record and I press the "Add Row" button there should be a new, empty second line with old second record in the third line,... the old ninth record now in line 10 and disappeared record ten ?
Any idea ?
Thanks,
Heinz

Heinz,
You may investigate logic using UNIONs and a manual tabular form.
Something like:
--get all records above new row
select apex_item... column1
,apex_item... column2
from yourtable
where <logic to limit rows above new record>
union
--get the new row
select apex_item... column1
,apex_item... column2
from dual
where :REQUEST = 'ADDROW'
union
--get every row not in the top query
select apex_item... column1
,apex_item... column2
from yourtable
where <logic to pull all records not pulled above new record>
For this to work you'll need to add your own "Add Row" button and associate it with a branch. Notice the select between the two unions in the above query is a select against dual. This will be your new record when pressing your "Add Row" button (:REQUEST = 'ADDROW').
The following how-to link is a reference for some of the logic you'll need when creating a manual tabular form.

Good Luck,

Read Only page/region attribute - Tabular form

APEX 4.2.1/Oracle 11.1
The new readonly attribute at the page and region level works very nicely to make a page readonly without having to set the readonly condition individually on each page item. Great job.
But I noticed that tabular form inputs don't honor this setting. Is there a easy way to make a tabular form readonly as well i.e. make it look like a classic report instead of showing input (even disabled) fields?
I guess we can clone the region as a classic report region and conditionally show one or the other but that's not ideal from a maintenance perspective.
Thanks

Marc - Thanks for logging the enhancement request. Couple of observations
1. The Copy Region wizard allows us to copy a tabular form region (along with its associated processes and buttons) but running the page raises errors since APEX only allows one tabular form per page. Perhaps the Copy Region wizard should check for this
2. Most tabular form regions are customized after the wizard creates them. Column headings are changed, display types, number/date formats, column links, etc. Re-doing all this to create a copy of the tabular form region as a classic report region is a bit of a chore. Maybe you can think of a easier way to do this in 5.0. Really all that needs to happen is change the Display As for all the tabular form INPUT fields to Display as Text and preserve all other customizations.
Thanks

Multiple select lists in tabular form

Hi,
I created a tabular form with two select lists (Queries are same for both the select list and results around 300 records in the SQL).
I am getting the following error:
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
If I changed Select list to POP list, I am not getting error.
Please suggest how to user select list in this case.

Meda

Please suggest how to user select list in this case.It is not possible. There is a 32K limit on the HTML generated for select list items. (As a type of report, tabular forms are also subject to the 32K limit on the size of a report row.)
In terms of usability 200 options is about the maximum size I would consider sensible for a select list ( and for select lists in tabular forms, much, much fewer!)
Use Popup Key LOVs.

Select records across multiple pages

i have a resultset of 100 records. 10 records are displayed and pagination is displayed for the users to navigate to other pages. All this is accomplished using jstl.
if the user selects 2 records on page 1, navigates to page 2 and selects 2 more records, only the records from page 2 get selected. how can the records from page 1 and page 2 get selected? how can i retain selected records between pages?
can anybody please point me to some code snippets?
Thanks,

Oracle WCI - How to make Contact page in a tabular form in WCI

Hii All,
Im using Oracle WebCenter Interaction . As you all know that in websites we have a section called Contact-Us under whcih we can provide few contact details. Im using a portal which has been made by using WCI so i just wanted to make a table in a page which can show the contact details. My portal has a page which already has those contact but it is not properly alligned so i just wanted to make it in the form of table.One cantact on one row like that. Please give me any suggestion to make it.

Well i give u item level to apply it in the whole record including...
emp , ename & sal
any way to do it block level u can use Current Record Attribute Property block level but if u programatically do it as mentioned u can have a lock on something resemble to ur case pls have a look at Craig's Oracle Stuff How to Select Multiple Records in a block using Record Groups just to exclude the idea u want to develop.
Hope this helps...

Help needed in row selection in Tabular form across pages

Hi,
I have a tabular form report similar to http://htmldb.oracle.com/pls/otn/f?p=31517:95. I want to select some rows from first page and then use the pagination to get to the next page, select some more rows and hit the submit button for processing. The rows selected in the last page alone are picked up for processing, and the ones selected in the earlier pages are lost. I see the same behaviour in Denes' example as well. I picked a row in the first page and a row in the next page, and then click "Pick Records", i see only the record i picked on the second page.
I did play around with "partial page refresh" setting for the tabular form region, but that does not help.
Is there a way to select across pages in a tabular form?
thanks,
Rams
Edited by: rams1234 on Jan 22, 2009 10:19 AM

Okay. I could make this work, but this seems to be a roundabout way for me. In my case I dont have any database related query to get the values, hence the Application level process may not be needed.
When I select the checkbox, i get the value. I am hoping that I should be able to send the value to a javascript function and update the filed value in the function itself. Please see the function below..
function setFileID(pThis) {
var chkvals=pThis.value;
var fldValue = new $x('f_FILELIST').value ;
if (fldValue != 0)
{ $x('f_FILELIST').value= fldValue+'-'+chkvals;}
else
{ $x('f_FILELIST').value = chkvals ;}
This function works fine in making up the list. The issue is, when an already selected row is unselected, the value of the checkbox gets added one more time :) If I detect the checkbox status and subtract the corresponding value, this will be perfect..
Thanks for the link anyway. I am marking this question answered.
regards,
Rams.

Losing data on a tabular form when submitting a page with validation errors

I have a window that has a regular HTML form at the top that has several items. Then on the bottom of the page, I have a tabular form where the user can enter multiple rows of information. Unfortunately, when the page is submitted, if there are any validation errors, any changes that were made in the tabular form are lost.
Any suggestions

Fair enough :)
Actually what I was meaning was could I use a collection to repopulate the tabular form when I receive errors. It appears as if it may work. However, I am hitting one snag.
I have created a PL/SQL Process that runs On Submit and Before Computations/Validations. In this process, I have saving the values in the tabular form to a collection.
I was then hoping to create another process that ran after any errors occur. However, it does not appear as if any processes run when the screen redraws after a validation issue. Is there a process that runs after validations when the screen is redrawing? Will I need to do this using javascript?
Thanks
