Tabular forms and pagination

Hi
I am trying to build a tabular form in which users can add/modify hours worked on tasks by day in a month. The layout of the form is
Name Month Total Mon 2/1 Thu 3/1 ... 31/1
task1 | January | 40 | 6 | 3 ... 5
task2 | January | 22 | 2 | 5 ... 3
task x
I use javascript (found in this forum) to calculate totals (by day and by task) and to show/hide columns (weekends). When users have lots of tasks (30+) the performance (calculate/show/hide) is very low, when I use pagination, changes made by users are lost when going to the next records.
My first attempt was using the wizard, now I'm looking at collections (seems a better choice) so can somebody point me in the right direction to accomplish a form based on a collection with pagination (collection gets updates when moving to the next records) and a button to apply the collection to the database.
Thanks in advance
Andre

This is not easy.
Pagination uses HTTP GET to fetch the next/previous set of records. It does NOT submit the current page so all changes made on the page are not saved back to the database.
You just have to train your users to click Save/Apply Changes before paginating away from the page.
Or you see Saving session state during pagination for some hacks I did.
Also see Pagination and saving changes

Tabular Forms and Select Lists

Hi,
I have an updateable tabular form, and one of the updateable columns I want as a select list. I need the SQL that populates this select list to be based on a hidden value in the tabular form. Is this possible?
Cheers
Simon

Hey Simon,
Sounds reasonable, you'll have to end up using the HTMLDB_ITEM.SELECT_LIST_FROM_LOV function within the query that is populating your form.
http://www.acs.ilstu.edu/docs/Oracle/appdev.101/b10992/mvl_api.htm#CHDFGAEC should give you a bit more help towards sorting it out. Don't hesitate to post again if you have anymore queries.

Hi,
I believe the error is due to the checksum process which doesn't have that additinoal field's information. You can try creating the form again with the additional field, or if needed you can go with the Manual tabular form.

Across row validation in tabular form and across items in row validations.

Hi,
We are upgrading to APEX 4.0.
I need to create a tabular form that will have a start date and an end date. FOr each new row or updated row I need ensure its start date is after the end date of all rows already entered and its end date is after the start date of row being entered. Also that if no end date is entered then no other rows can be found with a null end date.
SO I need across field validations with in a row and across row validattions. That is I need rowset validations as well.
Is it possible to do this with APEX? WHat kind of tabular solution would allow these type of validations. How might these validations be done?

Okay, Here's a quick rundown on how to build a manual form using APEX_ITEM and collections. The process goes in 4 steps: gather the data, display the data, update based on user input, then write the changes. Each step requires it's own piece of code, but you can extend this out as far as you want. I have a complex form that has no less than a master table and 4 children I write to based on user input, so this can get as complex as you need. Let me know if anything doesn't make sense.
First, create the basic dataset you are going to work with. This usually includes existing data + empty rows for input. Create a Procedure that fires BEFORE HEADER or AFTER HEADER but definitely BEFORE the first region.
DECLARE
v_id     NUMBER;
var1     NUMBER;
var2     NUMBER;
var3     VARCHAR2(10);
var4     VARCHAR2(8);
cursor c_prepop is
select KEY, col1, col2, col3, to_char(col4,'MMDDYYYY')
    from table1
    where ...;
i         NUMBER;
cntr      NUMBER := 5; --sets the number of blank rows
BEGIN
OPEN c_prepop;
    LOOP
      FETCH c_prepop into v_id, var1, var2, var3, var4;
      EXIT WHEN c_prepop%NOTFOUND;
        APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => v_id, --Primary Key
        p_c002 => var1, --Number placeholder
        p_c003 => var2, --Number placeholder
        p_c004 => var3, --text placeholder
        p_c005 => var4 --Date placeholder
    END LOOP;
CLOSE c_prepop;
for i in 1..cntr loop
    APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => 0, --designates this as a new record
        p_c002 => 0, --Number placeholder
        p_c003 => 0, --Number placeholder
        p_c004 => NULL, --text placeholder
        p_c005 => to_char(SYSDATE,'MMDDYYYY') --Date placeholder
end loop;
END;Now I have a collection populated with rows I can use. In this example I have 2 NUMBERS, a TEXT value, and a DATE value stored as text. Collections can't store DATE datatypes, so you have to cast it to text and play with it that way. The reason is because the user is going to see and manipulate text - not a DATE datatype.
Now build the form/report region so your users can see/manipulate the data. Here is a sample query:
SELECT rownum, apex_item.hidden(1, c001), --Key ID
     apex_item.text(2, c002, 8, 8) VALUE1,
     apex_item.text(3, c003, 3, 3) VALUE2,
     apex_item.text(4, c004, 8, 8) VALUE3,
     apex_item.date_popup(5, null,c005,'MMDDYYYY',10,10) MY_DATE
FROM APEX_COLLECTIONS
WHERE COLLECTION_NAME = 'MY_COLLECTION'This will be a report just like an SQL report - you're just pulling the data from the collection. You can still apply the nice formatting, naming, sorting, etc. of a standard report. In the report the user will have 3 "text" values and one Date with Date Picker. You can change the format, just make sure to change it in all four procedures.
What is critical to note here are the numbers that come right before the column names. These numbers become identifiers in the array used to capture the data. What APEX does is creates an array of up to 50 items it designates as F01-F50. The F is static, but the number following it corresponds to the number in your report declaration above, ie, F01 will contain the primary key value, F02 will contain the first numeric value, etc. While not strictly necessary, it is good practice to assign these values so you don't have to guess.
One more note: I try to align the c00x values from the columns in the collection with the F0X values in the array to keep myself straight, but they are separate values that do NOT have to match. If you have an application you think might get expanded on, you can leave gaps wherever you want. Keep in mind, however, that you only have 50 array columns to use for data input. That's the limit of the F0X array even though a collection may have up to 1000 values.
Now you need a way to capture user input. I like to create this as a BEFORE COMPUTATIONS/VALIDATIONS procedure that way the user can see what they changed (even if it is wrong). Use the Validations to catch mistakes.
declare
j pls_integer := 0;
begin
for j1 in (
select seq_id from apex_collections
where collection_name = 'MY_COLLECTION'
order by seq_id) loop
j := j+1;
--VAL1 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>2,p_attr_value=>wwv_flow.g_f02(j));
--VAL2 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>3,p_attr_value=>wwv_flow.g_f03(j));
--VAL3 (text)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>4,p_attr_value=>wwv_flow.g_f04(j));
--VAL4 (Date)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>5,p_attr_value=>wwv_flow.g_f05(j));
end loop;
end;Clear as mud? Walk through it slowly. The syntax tells APEX which Collection (p_collection_name), then which row (p_seq), then which column/attribute (p_attr_number) to update with which value (wwv_flow.g_f0X(j)). The attribute number is the column number from the collection without the "c" in front (ie c004 in the collection = attribute 4).
The last one is your procedure to write the changes to the Database. This one should be a procedure that fires AFTER COMPUTATIONS AND VALIDATIONS. It uses that hidden KEY value to determine whether the row exists and needs to be updated, or new and needs to be inserted.
declare
begin
--Get records from Collection
for y in (select TO_NUMBER(c001) x_key, TO_NUMBER(c002) x_1,
             TO_NUMBER(c003) x_2,
             c004 x_3,
             TO_DATE(c005,'MMDDYYYY') x_dt
           FROM APEX_COLLECTIONS
           WHERE COLLECTION_NAME = 'MY_COLLECTION') loop
    if y.x_key = 0 then --New record
        insert into MY_TABLE (KEY_ID, COL1,
            COL2, COL3, COL4, COL5)
          values (SEQ_MY_TABLE.nextval, y.x_1,
              y.x_2, y.x_3, y.x_4, y.x_dt);
    elsif y.x_key > 0 then --Existing record
        update MY_TABLE set COL1=y.x_1, COL2=y.x_2,
             COL3=y.x_3, COL4=y.x_4, COL5=y.x_dt
         where KEY_ID = y.x_key;
    else
      --THROW ERROR CONDITION
    end if;
end loop;
end;Now I usually include something to distinguish the empty new rows from the full new rows, but for simplicity I'm not including it here.
Anyway, this works very well and allows me complete control over what I display on the screen and where all the data goes. I suggest using the APEX forms where you can, but for complex situations, this works nicely. Let me know if you need further clarifications.

Create Check box in Tabular form and report

This is Marilyn. I wanted to know if anybody can help me with the following scenario.
I created tabular form which has some LOV columns, and some check boxes. When the user clicks on "add row" button, I want to populate the row with the values from the LOV display to be selected by user, and some of the blank check box also display as empty check box in order for user to select check or uncheck them.
If this is possible, can you provide an example?
Thanks

Apex, Tabular forms and Nested Tables := Headache

Hi All,
I'm constructing an Apex aplication for Performance Reviewing staff and I have need of nested tables within each line item for ongoing comments during the year, the headings of which are drawn from another table, based on a template for which ones are to be used at any given time.
I'd like to be able to use a tabular form to draw out the history of comments at any given time and modify them however I'm at a complete loss as to how to get this working with a tabular form in Apex. If anyone could point me at some good documentation on the subject or even suggest a better method to get this done I'd be very grateful.
Thanks!

Hi,
Take a look at this article:
http://www.oracle-base.com/articles/misc/ObjectViewsAndNestedTables.php
First, create a view as described on your nested and other table(s), with 'Instead Of' triggers handling the DML. Next create the tabular form based on the view. You'll find many posts in the forum regarding building a tablular form based on a view.

Manual tabular form and query based LOV

Happy new year everyone!
Okay so, I've run into an error when making one of the fields in a tabular form into a select list.
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
The query works fine in SQL Workshop and Toad, it returns over 100 rows.
I have tried to use a Popup LOV, which works but I'd like to know what is going wrong with the select list.
We're using version 3.0.1.00.07 of apex, for what it's worth.
Help appreciated!

Keiran,
In the select list there is a display value and a return value.
The return value is the Foreign Key and the Display value is what is displayed in the LOV.
Are you getting these the wrong way round ?
I usually put the return value first and alias is with r and put the display value second and alias the display value with d.
Hope this helps
Regards
Chris

Tabular Form and Link to document and No Data Found error

I have used this numerous times in an INTERACTIVE REPORT to link records out from the report to a document in a folder on our server and it works beautifully thanks to one of you guys who helped me a couple of years ago. In the column for which I want to use as a link I do the following:
LINK TEST #ISO_NUMBER#
LINK ATTRIBUTES a href=#DOC_LINK#; TARGET="_BLANK"
URL #DOC_LINK#
I've been banging my head against the wall trying to figure out why I keep getting a 'No data found' error in my TABULAR FORM. The good news is I figured out why it's happening. The bad news is I do need to link out to the documents listed in my tabular form that are saved on the server.
Is there any other way to do this?
Application Express 4.0.0.00.46
TIA,
Alexandra

Finally back...
I have a tabular form that lists documents stored on one of our servers. In an interactive report I can set up a link to those docs using the document number column in the IR. I can't get it to work in the same way on the tabular form. Hopefully the steps of the catalog process will shed light on what may be the problem:
Step One
1. User1 catalogs doument using standard form (page 3) on DOC_INFO table.
2. Button on form redirects to Approval Tabular Form (for this example, page 100). This tabular form displays DOCUMENT_NUMBER (display as text saves state), APPROVER (select list), APPROVED(select list), RELEASED (select list) fields among others from DOC_APPRV_DOC table
3. Add Row adds fields in #2 above and other fields
4. User1 selects APPROVER in select list and Adds Row for all additional APPROVERS required
5. User1 hits SUBMIT button
Step Two
1. User2 opens different page but Approval Tabular Form (for this example, page 200) on same DOC_APPRV_DOC table, restricted to :P101_USERNAME
2. User2 uses APPROVED select list to approve or reject
3. User2 hits SUBMIT button
Step Three
1. User1 opens Approval Tabular Form (page 100) with User2 (and all other documents requiring approval) results
2. If rejected User1 uses Reset Approval checkbox and select list on User2's tabular form is reset
3. If approved User1 uses Released submit list and and record is deleted from User2's tabular form
The Problem
User2 ought to be able to review each of these documents on the server. In other parts of my application, an interactive report is used, I've got a case statement in the report creating the link, and have the column itself setup up so that User2 merely clicks on the DOCUMENT_NUMBER on the report and he's redirected to the document itself.
This works fine when set up the same way on the tabular form ONLY THE FIRST TIME a row is added. If I ADD ROW for any additional documents the DOCUMENT_NUMBER field on the tabular form does not populate on User1's form.
The entire process works beautifully if the link is not set up.
Note that from the standard form, the DOCUMENT_NUMBER is sent to a hidden item (default = :P3_DOCUMENT_NUMBER) in a region above the tabular form (page 100). This is then used to populate the DOCUMENT_NUMBER on the tabular form as the default value (:P200_DOCUMENT_NUMBER).
Your thoughts? Thanks in advance!
Alexandra

Manual tabular form and hidden fields

Hi,
I have a manual tabular form with some hidden fields, one for the primary key and one to handle my checkbox.
The checkbox handling I got from here:
http://htmldb.oracle.com/pls/otn/f?p=31517:123:4202825883202781:::::
Here you can see my very simple example:
http://apex.oracle.com/pls/otn/f?p=22968:3:4142231640027285:::::
My query:
select
to_char(dag,'day dd mon yyyy') dag
, HTMLDB_ITEM.HIDDEN(1,pk) pk
, htmldb_item.text(2, ben1) ben1
, htmldb_item.text(3, ben2) ben2
, htmldb_item.text(4, ben3) ben3
, htmldb_item.text(5, ben4) ben4
, htmldb_item.hidden(6, cb1) cb1_hidd
, htmldb_item.checkbox(7, ROWNUM, NULL,DECODE (cb1, 'Y', ROWNUM)) cb1
from dummy
My problem is that I don't want to show the columns hidden_pk and hidden_cb1. But if I set them to not shown they are not parsed in my html page. Maybe that's all natural but how do I handle this problem??
Any ideas?
Regards Daniel

Stick them to another item, like this
select
to_char(dag,'day dd mon yyyy') dag
, htmldb_item.text(2, ben1) || HTMLDB_ITEM.HIDDEN(1,pk) ben1
, htmldb_item.text(3, ben2) ben2

Need help with Apex 4.0 tabular form and searchable select list

I would like to use an exisiting plugin for a searchable combo box on a tabular form. When I define the item types on my tabular form I don't see the plugin as an option. I reviewed the help documentation for the apex_item api for the tabular form but I didn't see how I could reference the plugin. Has anyone done this or have other ideas? Any help would be greatly appreciated.

I noticed this problem in the first beta version but I thought this is so obvious and it will be corrected so I didn't follow on it further. This looks like a bug in 4.0. If I use firebug, I will see that the selected value is still RESEARCH allthough the display changes - <option selected="selected" value="20">RESEARCH</option> If I click on SAVE than wrong values will be changed.

Manually Created Tabular Forms and Firefox 4 Problem

I have a tabular form created with pl/sql dynamic content regions using the apex_item toolkit. An apex collection is used to maintain state for the tabular data entered. It is an application originally created in APEX 1.5 and upgraded through the years to 3.2 . Never a problem with the application until now. I have re-created the issue on the apex.oracle.com site here:
http://apex.oracle.com/pls/apex/f?p=28213
Run the application in IE ( I am using 8) and then run in Firefox 4. Enter a quantity in the first item then hit Next and then Previous multiple times. See the problem? The problem does not occur in FF 3.6 or Chrome either. I have not tried Safari as my mac is at home and I am at the office.
Here is code for both pl/sql regions and the collection update (after submit). Page 2 is just a report selecting from the collection. I have spent a day trying to solve this problem. Any help will be appreciated. Re-architecting without the pl/sql dynamic regions is not an option at this time.

Dave,
All I am saying is both of your report regions can very easily be made into a sql statement and put into a report region. you can then use the apex builder to format them. How you validate that data is up to you and would not change all that much other than making sure your global arrays are pointing to the same columns. it just looks to me that you are going through a lot more effort to not use what apex will very easily do for you. Plus the more apex built in functionality you use the more robust your application will be in different browsers.
I tried running your application in IE 7 and FF 3.6 and i did not see any problems. i entered 1,6,4 clicked next. Clicked previous numerous times and was redirected back to the page and saw 1,6,4.
What is happening when you run the app?
Thanks,
Tyson Jouglet

Form and Pagination Advice

I need to create an application in Portal that takes in user input, validates the input and, if valid, directs the user to another portlet. Something like this:
if form(portlet)1 valid then go to form(portlet)2. if form(portlet)2 is valid then go to form(portlet)3. if form(portlet)3 is valid then submit all of the entered data to a backend system.
I'm thinking that these would be html forms, caching the data and then submitting. Hope this makes sense. Right now I'm looking for an approach that I could build using Portal Builder and not writing a java or pl/sql portlet. Thanks for any help in advance.

Hi,
Here is the better design approach for your scenario. No need to jump from portlet 1 to portlet 2 and then portlet 3.
With this suggested approach you can full fill your requirement in a single portlet.
Just design a jsp in such a way that there will be three tabs at the top
say Present Address Official Address Native Address
and there will be a Next button and Submit button at the bottom of the page.
By default Present Address tab will be selected and there you enter values for present address details.
once you enter this detail just click on the Next button to enable Official Address tab and enter your official detail there.
Once done with completing official detail , again click on Next button which will result in enabling third tab that is Native Address and here you enter your native address detail.
Finally click on the Submit button to store all the address details to the back end.
On each click of Next button you validate the values entered for that address detail.
here you will have to play a bit with div and java script.
i hope you can visualize the design which i am trying to explain.
do let me know if you have any confusion.
Thanks

Interactive report limits tabular form pagination.

Hey All,
I am running into a problem and I was unable to find an answer on the forum, however I did find that someone asked the same question but did not get any replies. So I will ask it again.
Pagination problem with interactive report and multi row update form
I created a page which contains both an IR and a tabular form. The IR behaves correctly and there are no issues. The tabular form on the other hand is not functioning properly. The problem I am having is that the tabular form will only paginate to the rows that are currently being displayed in the IR. For instance if I am viewing rows 6-10 on the interactive report the tabular form will start from row 6 even if my pagination scheme is set to view in increments of 20.
Another example is if the IR is is viewing rows 6-10 and the tabular form is viewing rows 1-2. If I paginate on the tabular form it will jump to rows 6-7 regardless of where its last position was.
So in short it appears that my tabular form always starts from the first row currently being viewed in the IR. Is there a work around for this or should I just ditch the interactive report?

Munky,
Thanks for the suggestion. It does indeed allow me to paginate but I hate the alert you get when PPR is enabled for a tabular form and unfortunately so do the users. :(

Not null and enable or disable column in tabular form

Hi,
Using apex version 4.1 and working on tabular form.
ACT_COA_SEGMENT_MAS is Master table
and
ACT_SEGMENT_VALUES_MAS is detail table
I have entered 8 rows in master table and PARENT_SEGMENT_ID is column in master table which is null able. If i specified PARENT_SEGMENT_ID with value in master table then in detail table there is column PARENT_ID that should not be null and enable.
How i can enable or disable column when in master table PARENT_SEGMENT_ID column is null then in detail table PARENT_ID column should disable and vice versa.
I have created tabular form on Detail table. before insert into the tabular form Check in master table in first entry if PARENT_SEGMENT_ID is not null in first row of master table then in tabular form PARENT_ID should enable and not null able in corresponding to this first row id's lines in tabular form.
Same should check for second row in master table if PARENT_SEGMENT_ID is not null then entered rows with PARENT_ID into tabular form corresponding to 2nd id in master table should not nullable and column should enable in tabular form.
Thanks & Regards
Vedant

Vedant,
You need to create you own manual tabular form and not use the wizard.
Using APEX_ITEM api you should be build you own form and you will be able to control how you wan to display the rows. (See Link [Apex Item Help|http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_item.htm#CACEEEJE] )
select case when PRIMARY_TABLE_COLUMN is null then APEX_ITEM.DISPLAY_AND_SAVE(3 , DETAIL_COLUMN ) else APEX_ITEM.TEXT(2,detail_column) end "ALIAS" from detail table
Hope that help.
