Initializing the date field in tabular form

i m creating one time sheet application. in that i hv created one tabular form to take timesheet entries. current_date attribute is one of them. the problem is that i want to initialize the current date with the sysdate as the form loads and then afterwards the user can edit the date using the calendar if he wishes to. the current_date type is date picker.
but the before header for computations is not showing thhe item and process is not allowing to create any pl/sql block..can any1 help me?

In the source of the column use PL/SQL Expression or Function and put there
SYSDATE (include some formating if you want). This will set the default value of the
field to what you want once you add new rows.

When creating a fillable form and saving it as a pdf, the default color of the data fields is a light blue. How do I change the color to something else that will copy better, e.g. a light yellow?

When creating a fillable form and saving it as a pdf, the default color of the data fields is a light blue. How do I change the color to something else that will copy better, e.g. a light yellow?

It's probably the fields highlight color of the application, which you can change via Edit - Preferences - Forms.

Strange error in online Adobe form for the date field

Hi Experts,
I am facing strange problem with online Adobe forms. I could able to save data when i click save button on the form.
But some times in the form the date field is throwing error message 'MMDDYYYY field is invalid' when i click on save button.
Is this the problem with versions of Adobe liveCycle designer, Adobe reader or GUI?
Thanks in advance,
Ram

Hi
Check the format (in the object pallete) of the date field in Adobe liveCycle Designer, If it is not set already set it according to your requirement. then see if it works
Hope this helps
Regards
Amita

The date field does not appear on my form

On my saved form, the date fields do not reveal the calendar icon to select a date like it does on the test form. The date field is instead a free text field. Can somebody explain what happened to the date field?
Thank you.

Hi,
If the form is saved as pdf, the date picker is not support in pdf.

Perry

What's the deal with 'no data found in tabular form' in apex 4.1

We recently upgraded to 4.1 to resolve some of the issue found in 4.0. I have a form that populates a collection....it had previously worked in earlier versions and now I receive the following error when I try and SAVE.
any thoughts?
Contact your application administrator.
no data found in tabular form

HI Joel, thanks for getting back to me.
We recently moved from apex 4.0 to 4.1. I have an application that makes use of collections. All was working in 4.0, but now I am having problems with 4.1. I would be happy to move place application in more convenient spot, but need specific instructions as I am not certain how to do that.
basically, I have a report region, FAVORITES based on a collection (source listed below):
SELECT apex_item.checkbox (1,seq_id, 'onclick="highlight_row(this,'
|| seq_id
||')"', NULL, ':', 'f01_'
|| LPAD (seq_id, 4, '0') ) delete_checkbox,
apex_item.hidden(2,seq_id) seq_id,
apex_item.hidden(3,seq_id),
apex_item.text_from_LOV(c004,'SPECIES')SPECIES_ITIS,
apex_item.text_from_LOV(c005,'GRADE')GRADE,
apex_item.text_from_LOV(c006,'MARKETCODE') MARKET_CATEGORY,
apex_item.text_from_LOV_query(c007,'select unit_of_measure d, unit_of_measure r from species_qc') unit,
apex_item.text(8,c008,5) fav_order,
apex_item.select_list_from_lov
(9,
c009,
'DISPOSITIONS',
'style="width:200px;background-color:#FBEC5D; "',
'YES',
'0',
'- Select Disposition -',
'f09_' || LPAD (seq_id, 4, '0'),
NULL,
'NO'
) disposition_code
from apex_collections
where collection_name = 'C_DEALER_SPECIES_FAV' order by seq_id desc, c008
The collection appears and I am able to add rows to this collection. The problem is when I SAVE. The following is executed (and again, works fine in 4.0).
declare
dispositionCode varchar2(3);
begin
delete from frequent_species where permit_id = :G_permit_id;
for rec in (select c004,c005, c006, c007,c008,c009,:G_permit_id from apex_collections where collection_name = 'C_DEALER_SPECIES_FAV')
loop
if rec.c009 = '0' then
dispositionCode := null;
else
dispositionCode := rec.c009;
end if;
insert into FREQUENT_SPECIES (species_itis, grade_code, market_code, unit_measure, fav_order, disposition_code,permit_id) values(rec.c004,rec.c005, rec.c006, rec.c007,rec.c008,dispositionCode,:G_permit_id);
end loop;
exception when no_data_found then null;
end;
I receive the message:
Contact your application administrator.

Return to application.
Let me know what you think. thanks for your help. Karen

Validate field in tabular forms apex 4.2

Hi.
i need help doing next validations :
1.- i have a product_item field (wich is a lov and user choose one value), so i need to call a function (sending it the selected value product_item) that will return me some data about the product i selected, for example :
if the function return 'A' then
disable the next item on tabular form, lets say quantity
else
enable the next item on tabular form, lets say quantity
end if
2.- i need to determine the result of two items operations:
total := final_quantity - start_quantity
the user will introduce start and final quantity and i will determine the total.
any ideas ?
i am new on apex and need to do this on tabular forms.
thanks in advance.

Thomas,
Is this a standard APEX tabular form validation, or a custom PL/SQL based validation? It might be easiest to diagnose what's going on there, if you could replicate this issue on apex.oracle.com, and point us to an example.
Thanks,
Marc

Error while updating Date Field on Process Form.

Hi,
I am using java code to pre-pop date on the process form.First I used a java code whic took java.sql.date as input and returned the same java.sql.date.But it gave an error that:java.lang.String cannot be converted to java.sql.date.......
So I changed the java code and now it takes string as input and returns java.sql.date. This code works fine for Pre-pop adapter and the date is populated on the process form.
But when i use the same code in a Process Task adapter to update the date, then it gives the following error:
ERROR [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' XELLERATE.ADAPTERS - Class/Method: tcAdpEvent/updateDataSetValuePost encounter some problems: Adapter Execution Error: updateDataObjFieldValuePost: error updating UD_OID_USR_DATE_OF_BIRTH
ERROR [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' XELLERATE.ADAPTERS - Class/Method: tcAdpEvent/updateDataSetValuePost encounter some problems: {1}
Can anyone suggest any method to update date field on process form?

Hi Abhi,
Can you tell me how you have implemented populating an UDF based on Prepopulation of another UDF. I have a similar kind of requirement. It would be great if you share your code or relevant part of it.

How do I set blank data to date field in pdf form ?

Dear Sir,
I made PDF form by Acrobat X on Windows PC and then,
read the pdf form by acrobat reader on iPad.
Date field is included in the form.
The Acrobat version is 10.1.6 .
The acrobat reader version is 10.5.0 .
First, I put the wrong date data to the date field.
So, I tried to clear the date field.
I want to put the blank data to the date, but I think
there are no way to put the blank data on iPad
I would like to know how to reset the date data.
If that helps, I tried to the same thing on Android.
I could put blank data to the date field by BS key.
Sincerely,

Here is how to clear the Date field on the Ipad.
NOTE: In order for this to work that has to be another TEXT field in the PDF to get the keyboard to pop-up.
Click on Text field (this is to get the regular keyboard on screen)
Click on Date field (date spinner control will show up)
Click on SAME DATE field (spinner control will disapper)
Click on "Reset Field" on top of keyboard (date field will now be empty)
Click any where on PDF that is not another Date field (keyboard will disappear and date field will be empty)
Bingo! your free and clear.

Displaying all the records in a tabular form on a single page

Hello,
After setting up a data entry page, I have hit an unexpected problem.
The logic in my page requires that all the records in my tabular form should be displayed .
The tabular form is based on a collection, and the user selects rows through a checkbox.
Any reload of the page due to pagination will break the logic, as some calculation and display events occur during page load,
based on the previous page.
I need to display about 25 rows.
I have changed the report attribute to display 50 rows, but it displays rows only up to the bottom of the screen,
i.e. 11 rows.
Unfortunately I only just added some new rows and saw this behaviour else I would not have gone that way,
as I expected APEX to display all rows if required.
Some help will be much appreciated.
Regards
Leckraj

For this change to be instantly visible, either log out, restart the brower, and log in again, or manually re-request the page from the browser address bar, adding 'RP' in the ClearCache position in the URL.

Populate select list when a date selected from date picker in tabular form

Hi Guys,
I have a situation where user picks a date from a date picker in tabular form.
So as soon as he picks a date say 05/31/2011 from the date picker I want to populate a select list with 2 values : Tuesday AM , Tuesday PM.
I have gone through the forums a lot and figured we can write a Dynamic Action using JQuery Selector. But I am not sure how to figure out the day from a date picker.
I appreciate if some one can give your thoughts on how to proceed. It seems to be simple but looks like a tricky one. I am not familiar with writing Java Script.
Thanks ,
Raj

I was thinking your date selected from CALENDAR ended in a list_item.
I don't know I thinking that
well,
:master_block.itemdate is your text_item where calendar return date selected.
and then , following Gerd's step
Create a WHEN-MOUSE-DOUBLECLICK on the date-item of CALENDAR and write :
begin
:master_block.itemdate := calendar (.........);
go_block ('master-block');
execute_query;
end;
or set a global or parameter variable date selected from calendar :parameter. xxxxxx
in a PRE-QUERY
:master_block.itemdate := :parameter. xxxxxx
and
Create a WHEN-MOUSE-DOUBLECLICK on the date-item of CALENDAR and write :
begin
:parameter. xxxxxx := calendar( ....);
go_block ('master-block');
execute_query;
end;

Hi,
You can use the date object FormsCentral provides. When you test the form in browser, the date field will show a pulldown calendar when clicked upon.

How can I validate a date field in Portal Forms

I have a date field in portal forms that I want to perform validation on to make sure it's in the proper format before being accepted (mm/dd/yyyy). How can I validate against that field?

Hi Ben,
I took the time to test and revise. This is code that will validate a date entry (format MM/DD/YYYY). Just paste this in the "Before the start of the form..." window of the Additional PL/SQL code section of the form. Then add validateDate(); into the onBlur event window of the field in question. Replace the CYCLE_END_DATE with the field name in question.
HTP.P('
<SCRIPT LANGUAGE=javascript>
function validateDate() {
var ddObj;
var mmObj;
var yyObj;
var day;
var mon;
var year;
var field_val;
var field_name;
for (var j=0; j < document.forms[0].elements.length; j++) {
field_name = document.forms[0].elements[j].name;
field_val = document.forms[0].elements[j].value;
if (field_name.substring(field_name.indexOf(''DEFAULT.'') + 8, field_name.lastIndexOf(''.01'')) == ''CYCLE_END_DATE'') {
var delimPos = field_val.search(/\//i);
if (delimPos < 0)
alert(''Invalid date entry! Please enter in MM/DD/YYYY format. '' +
''e.g, Dec 21, 2003 would be entered as 12/21/2003'');
else
if (field_val.length != 10)
alert(''Invalid date entry! Please Please enter in MM/DD/YYYY format. '' +
''e.g, Jan 1, 2003 would be entered as 01/01/2003'');
else {
month = field_val.substring(0, field_val.indexOf(''/''));
day = field_val.substring(field_val.indexOf(''/'') + 1, field_val.lastIndexOf(''/''));
year = field_val.substring(field_val.lastIndexOf(''/'') + 1, 10);
/* Need to subtract 1 from value because in Javascript, January begins with 0
and ends with 11 for December */
month = month - 1;
ddObj = new Date(year, month, day);
mmObj = new Date(year, month, day);
yyObj = new Date(year, month, day);
if (ddObj.getDate(ddObj.setDate(day)) != day)
alert(''Invalid day!'');
if (mmObj.getMonth(mmObj.setMonth(month)) != month)
alert(''Invalid month!'');
if (mmObj.getYear(mmObj.setYear(year)) != year)
alert(''Invalid year!'');
</SCRIPT>
');
