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)

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.

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:
http://www.oracle.com/technology/products/database/htmldb/howtos/checkbox.html#CHECKBOX_IN_REPORT
Hope this helps,

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 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 :)

I'm using Apex 4.02 11g and will be upgrading to 4.2 in the near future; woohoo.

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.

Tabular form with non base table field

I want to develop a tabular form with
1. A non-base table edit field to accept a value
2. Insert/update another table based on the input value
3. Also, computed field on each row based on other fields on the records (like post-query trigger in oracle forms at block level - for each row)
Thanks,
Rachna

Thanks for your reply.
Varad, I like the link you sent me. It has a lot of good information.
I created a process (under page processing) called "Update/Insert Process" that dosn't seem to be working.
Question, I created a manual tabular form with SQL Query and created a process (under page processing) called "Update/Insert Process", then I check for each record in the tabular form. If the old value <> new value then I update/insert in the new table.
Any step by step will be highly apprciated - to create process/validation etc.
Thanks,
Rachna

Tabular form with select list not updating

I have created a tabular form with a dynamic select list
select primary_key, column1,
htmldb_item.select_list_from_query(10,column2, 'select descr d, column_value r from lookup_table where column_value = '||column1) column2
from main_table
The select list appears to work correctly but the new value is not saved to the database. I assume this is because the tabular form element display as field for column2 is set to "standard report column" but when I select any of the "display as text" or "LOV" options either the current data is not displayed or errors are generated.
Any suggestions?
Thanks,
Bob

Hi Ian,
As you have seen, sorting on the project_manager_id column will sort by the id value rather than the textual value. This is, of course, because this is the value in the field.
I haven't tried this out, but one thing that may work is the fact that you don't have to include the ORDER BY fields within the SELECT statement. You could, for example, do:
select p.project_number, p.project_manager_id
from projects p, users u
where p.project_manager_id = u.id (+)
order by u.name
Obviously, you won't be able to do this in the existing statement as you would then be blocked from using column sorting. However, it implies that if you could construct the SQL statement dynamically, appending appropriate ORDER BY strings to the end of the base select statement, you could sort by anything you like. This does, of course, mean that you would have to create a mechanism to allow the user to select the sort order, generate the appropriate string and reconstruct the entire sql statement.
I had had a similar request quite a while ago. The underlying reason for that request turned out to be that the user just wanted to quickly locate records relating to one person. In the end, we agreed that a search filter was the best thing to do.

Andy

ADD ROW in tabular form with new max value for a certain field

All,
I have a tabular form with an 'ADD ROW'-button.
When a row is added the field 'TemplateID' should get
automatically a new value which is MAX from TEMPLATEID + 1.
I would be very glad, if someone has a hint for me.
Thanks in advance,
lucio

Hi
the cause of not seeing the 'Default Item Field' is,
that during creation of a 'Tabular Form' the column with the
primary key doesn't get that feature, why so ever.
I still hope that someone could give me a hint why that code isn't working:
function SetNewID(vDBID)
v_check = $v('P20_MAX_TEMPLATEID');
pNd = $u_Carray(vDBID);
     for(var i=0;i<pNd.length;i++){
          var node = $x(pNd);
          node = $x_Check_For_Compound(pNd[i])
          var lTr = $x_UpTill(node,'TR');
updateRow = lTr.rowIndex - 1;
document.wwv_flow.f02[updateRow].value=$v(v_check)
Many thanks in advance

SharePoint Custom New Form with DataForm Webpart SharePoint 2010

Hi Guys,
i have a Problem with my Custom NewForm.ASPX. I Created a CustomForm like this Guide:
http://www.ilikesharepoint.de/2013/11/sharepoint-create-custom-list-forms-with-visual-studio-part-2/
Problem
Now i set the DataFormWebpart for the Webpartzone on visible=False and add my custom DataformWebpart in this NewForm.aspx (see Code).
After my deployment and click on "New item" i can see my custom DataForm Webpart.
The Problems are:
1. The Ribbon is Greyed out
This post was not my solution. The Ribbons is not greyed out but the Ribbon has no function ("save Button" is broken)
2. The Fields are not loaded and looks like a Displayform
I Don't know why the Dataform does not load these fields. I can see the title but not the text Columns or lookups
3. Save Button and the Ribbon does not work
Only the Cancel button work on this Newform.aspx
The Save button has no function

I solved it.
I modified a bit my code "On load Page". In case of LOV i have changed this condition
if (l == undefined) {
          document.wwv_flow.f03.disabled = true;
      }with this
if (l == 105) {
          document.wwv_flow.f03.disabled = true;
      }I don't know why 105 instead of undefined, but this works. I give 105, with alert on length.

Bug: 4.1.1 Tabular form with all columns conditional

I need to make all the columns in a tabular form conditional because in some situations the editable elements should not be shown. For some reason just changing the columns to conditional stops the form working, the ApplyMRU/ApplyMRD process runs but does not action the changed rows. I can't figure out why at all or any workaround.
You can easily reproduce this in 4.1.1 by creating a tabular form with the wizard selecting one column in the form. Then make the row selector colunn and your editable column conditional using the plsql expression 1=1. The form is displayed the just the same with these true conditions but it doesn't work. How weird is that?
Rod West

Rod,
In your scenario the tabular form rendering engine is unable to place the hidden, internal tabular form status columns in your form, i.e. the columns that contain checksums, etc. The logic that places these columns looks for the last unconditional, visible column in your tabular form, and includes the hidden fields there. So you need at least one column that's always shown for this to work. This can be an otherwise empty column. I filed a bug (#13881803) for this, so we can look into improving this logic.

Marc

Date Picker on Manual Tabular form not working on 4.1 upgrade from 4.0

Hi
my application is upgrade from Apex 4.0 to 4.1 .
Oracle DB is 11g.
I have a manual tabular form with a date field:- apex_item.text(12,null,15,15,'class="datepicker3"') as end_date, After upgrade to 4.1 it's not working .
I changed the code to:- apex_item.date_popup2(12,null,15,15) as end_date, still not working .
I have to use apex_item.date_popup2 .
Thanks in advance !!!
-Amu

Hi Diana,
Is this you are trying to achieve:
piepdate = startdate + typeduration
The id attribute of the items in normal or APEX_ITEM based tabular form are of the type:
fxx_xxxx
For example: f10_0001, f10_0002, ..., f10_0010.
So, correct the vRow variable accordingly
>
// get row
var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
>
Hope it helps!

Kiran

Error tabular form with validation

Hi everyone,
I have built a tabular form with the wizard and I every time a validation check is done and fails,
getting an error in the place where the tabular form should be. I get to see the tabular form again when pressing the cancel button or refreshing the page.
I'm not quite able to reproduce this error, but I was wondering if anyone knows of this error and a workaround for it.
The error that's displayed is: report error: User-Defined exception
using Apex version 4.1.1. I've already tried building a new tabular form, but that didn't seem to resolve the issue.
I would appreciate the help.
Kind regards,
Cleopatra

Possible solution?
Validation returns : no data found + unhandled user-defined exception
See post by user 794496 there.

Tabular form with onhover comment column

Hi guys!
I was wondering if anyone of you saw an example of onhover item help with query...I mean..lets imagine a tabular form with a text field Comment column. Comment column has width 50 but we all know that comment ale like to be long ;) I'd like to see full lenght comment every time I put my mouse pointer on a specific row. Is it possible ? If yes can you show me an example or point me in a good direciton...(I dont know javascript well..)
With regards,
PsmakR

PsmakR,
Yes it is possible. Currently the ShowPopup script displays the value of current cell (hv_item.value). You can just simply replace with whatever you like.
If you're talking about the value of other columns, you may have to use document.wwv_flow.fXX to refer to it. Again, see my other sample of [Tabular Form Column Read-only|http://apex.oracle.com/pls/otn/f?p=57043:4] . Patrick Wolf wrote about this as well in his [ Which Tabular Form Column is mapped to which Apex_Application.g_fxx array|http://www.inside-oracle-apex.com/which-tabular-form-column-is-mapped-to-which-apex_applicationg_fxx-array/] .
