LOV in tabular form-Apex 4.0

Hi
I am creating a wizard based tabular form in Apex 4.0 and my scenario is like
I have a deptno column in my form and i want the employees for that particular dept in the ename select list.
I know that it can be done with manual tabular form. But since i am using a wizard based tabular form, is it possible for achieving this scenario.
Thanks.
Divya

Hi Vee,
I have tried your solution. I have replaced the column in my SQL with the apex_item version of the LOV. For showing the column correctly in the Grid I have to set the column to a "standard report column".
But Now it is now the edit flag is gone and it is not a updatable column anymore. When I push the Add button I cannot insert a value for the column.
How can I define the column as editable so the standard procedures for updating and inserting the column are working again.
Regards,
Fred.

PopUp LOVs in tabular forms

Hi,
I've discovered a problem using Popup LOVs in tabular forms, whereby on selecting a value from the LOV the key value is displayed on the form instead of the display value.
Having searched this forum it would appear I'm not the only one who has encountered this problem, but I've had no luck in finding an explanation for this behaviour or a solution / workaround.
Can anyone help?
Thanks
Andrew.

A Popup LOV is just a normal Input field with the option to popup another window, select a value and return that value to the field. On the popup window, the "display" value is shown to the user to make it easier to select the right value, but the "return" value is returned to the field as this is the value that needs to be stored on the database.
As a normal input field, it can only hold and, therefore, display one value.
Select Lists, on the other hand, store the "return" value but show the "display" value because that is how Select Lists are designed to operate.
You can show the "display" value in a second field for data that is already on the database by using the "Display as Text (based on LOV, does not save state)", based on the same database column as for the Popup LOV field and using the same LOV table.
However, the only way to get a "display" value for a new/edited record would be to either submit the page or design your own popup which can pass values back into two fields. Either way, you need two fields.
Unless someone else has found a way around this?????

Andy

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,

Dependent LOV in Tabular Form

All,
We are developing an application where we come across requirement to have two fields in tabular form and both are required to have LOV. But the issue is the second field LOV in the tabular form is dependent on first field value.
ex: Assume first field is "Country" and second field is "Cities", when user selects first field country as "US", then we have to populate list of citiies in "US" for that row. And if the user selects country as "UK" for the second row, we have to populate second field (city) with list of citieis in "UK".
We are unable to achieve this functionality and any help/pointers would be highly appreciated.

Hi Ram,
Please have a look at this example by Denes Kubicek
[http://apex.oracle.com/pls/otn/f?p=31517:176|http://apex.oracle.com/pls/otn/f?p=31517:176]
I was able to achieve the cascading LOV functionality based on the above example.

Theme 23 does not display popup LOV in tabular form

I created new application using new Theme 23. In tabular form the popup LOV button does not show. While using this theme the column LOV button is soooooo small it is not visible. If I move the cursor on the side of the field eventually I cursor handle will change and I can click and popup LOV will show. When I switch to an older theme (e.g. 21) the LOV button shows just fine.
Does anyone can offer a solution? Can I expect more this type of problems in the new theme 23?

I examined exported application file. Indeed the problem is p_column_id parameter. It should be decimal number for translated application. Characters %2C in p_column_id value stands for comma. It should be dot instead. Parameter value should be p_column_id=30289208519476123679.915121.

Select query based LOV for tabular form attributes

Hi HTMLDB Team,
Congrats u all for the new release of HTMLDB in htmldb.oracle.com.
I badly need a solution of the below problem.
Say , i have table called user_col_comments now i want to display the table_name ,column_name and comments in a tabular form.I displayed only one row for the tabular form.Now i create a select query based LOV for attribute table_name where i got all table_name in drop down list.
Point is that after selecting any data from drop down table list i want to get the corresponding fields to be populated in column_name attributes.How can i wrote the select query based LOV for the attibute column_name.
I wrote it as 'select column_name d,column_name r from user_col_comments where table_name=:TABLE_NAME Its not working?
Similarly i want same thing to display for comments after matching both table_name and column_name.
Any solution to get rid of those problem will be highly appreciable...
If u need my htmldb.oracle.com userid and password to solve the problem i will sure let u email it.
Cheers,
Eman

No Data returned for tabular form APEX 4

Hi,
I have a page that uses a tabular form, however it is not showing me any data. If I click the add row button and enter some details and press submit, the data is saved to the database but the page is refreshed and still shows me no data. I don't however get a No Data Found message.
If I create a region on the same page based on a sql report, that returns the data I have added through the tabular form.
Any ideas
Cheers
Paul

My previous post appears to be incorrect as neither pages are now returning data!!!!
So I started again and this is what I have done.
1) Run the page and get no data. The SQL statement on the page is
select
"ID",
"ID" ID_DISPLAY,
"REFERRAL_ID",
"REASON",
"CREATED_BY",
"CREATED_ON",
"UPDATED_BY",
"UPDATED_ON"
from "#OWNER#"."REFERRAL_REASON"
where referral_id = :P82_REFERRAL_ID
2) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (12 in this case)
3) Traced the page and looked at the trace file which has the following statement
select NULL "CHECK$01",
NULL "ID",
NULL "ID_DISPLAY",
to_number(123) "REFERRAL_ID",
NULL "REASON",
NULL "CREATED_BY",
NULL "CREATED_ON",
NULL "UPDATED_BY",
NULL "UPDATED_ON",
NULL "ROWID"
from dual
union all
select "CHECK$01" "CHECK$01",
"ID" "ID",
"ID_DISPLAY" "ID_DISPLAY",
"REFERRAL_ID" "REFERRAL_ID",
"REASON" "REASON",
"CREATED_BY" "CREATED_BY",
"CREATED_ON" "CREATED_ON",
"UPDATED_BY" "UPDATED_BY",
"UPDATED_ON" "UPDATED_ON",
"ROWID" "ROWID"
from (select NULL "CHECK$01",
"ID" "ID",
"ID_DISPLAY" "ID_DISPLAY",
"REFERRAL_ID" "REFERRAL_ID",
"REASON" "REASON",
"CREATED_BY" "CREATED_BY",
"CREATED_ON" "CREATED_ON",
"UPDATED_BY" "UPDATED_BY",
"UPDATED_ON" "UPDATED_ON",
"ROWID" "ROWID"
from (select "ID",
"ID" ID_DISPLAY,
"REFERRAL_ID",
"REASON",
"CREATED_BY",
"CREATED_ON",
"UPDATED_BY",
"UPDATED_ON"
from "IMPULSE"."REFERRAL_REASON") apex$_rpt_src
order by 1)
call count cpu elapsed disk query current rows
Parse 4 0.00 0.00 0 0 0 0
Execute 4 0.00 0.00 0 0 0 0
Fetch 16 0.00 0.00 0 24 0 12
total 24 0.00 0.00 0 24 0 12
4) Amended the page to remove the where clause
5) Amended the page to removed the process that adds 5 empty rows
6) Run the page and still get no rows
7) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (12 in this case)
8) Log out of application and log back in
9) Run the page and get 500 rows
10) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (500 in this case)
11) Added the where clause back in to the SQL statement and rerun the page and get the correct numer of rows (12 in this case)
12) Log out of application and log back in
13) Run the page and get no rows!!!!!!!
14) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (12 in this case)
So I can only conclude that whilst the data is being retrieved from the database it is not being displayed on the screen. So what would be stopping the data from being displayed?

Dynamic LOV FOR TABULAR FORM 6i

Hi,
I have tabular form of two Items(ID,DESC) and I want to Populate LOV for item(ID) every record
and record_Group & SQL statments are stored in DB.
ACTION: when query in POST-QUERY Trigger get for every record in tabular form -- the stored SQL-Statment from table then put it into dynamic record_group and populate the dynamic LOV.
Please advice,
Thanks in Advance.

OK daniel
This form used for get reports
then header get the name of Report (Table-A) (report_ID),(report_desc).
then details for get the Parameters will send to report builder (Table-B) (detail_id),(report_id),(sql_stm).
so parameters may be need for example stock code so this record need to query from stocks table to get stock code and stock name.
next record for item Code so need to query from Items table to get the Item code and Item name
another report for employees so the user enter report code then when query and get in details block employee code and employee name.
so the lov will check if this record have query sql-statment or not if have execute it in the record_group then in lov
then go to the next record if sql_stm is null then no lov in this record and so on.
thanks..

Validation problem on tabular form APEX 4.2

Hi,
My APEX Version is 4.2.
I have problem with validations on tabular forms, for example : I have a column who must be numeric... when I get a character it is controlled properly, but it removes my line of the screen and he writes in the table below:
state error:
ORA-01403: no data found
ORA-06510: PL / SQL: exception defined by the user untreated
I Haven't this problem with this application on APEX 4.0
PS : the validation was automatically create by APEX

Using LOV on Tabular form

I want to use Select list in tabular form. I have to columns. 2nd select list would depend on valuse of 1 select list. I knkw how to do it in simple form but I don't know how to do it in tabular form. Please advise

Are you asking for a "Select List with Submit" on the first column and a simple "Select List" on the second column? If so, you can't have a "Select List with Submit" on a Tabuar Form.

Dynamic Lov in Tabular form

Hi,
I'm creating select lists in tabular forms
and 2 select lists in it.
I'd like to use 1st list as a filter of 2nd list dynamically.
How can I do that?
Please advise me.
I found one tips(http://htmldb.oracle.com/pls/otn/f?p=18326:54:10017106699293281168::::P54_ID:1282) and I tried to do it but it didnt work...
Thanks

Hi,
There's several postings in the forum on how to do this, so if this message doesn't make sense, search the forum some, maybe for my Name?
If I remember correctly, using the following as an example, to something similar. This is based on a country and state lookup.
field 1 (:P1_country):
select distinct country from lu_location;
field 2 (:P1_state):
select distinct state from lu_location
where country = :P1_country;
Make :P1_country a 'Select List with Submit', and it 'should' work. I'm at home, so I don't have access to my database.

Dynamic action on LOV using tabular form

Hello,
I realize this has likely been dealt with somewhere already, but I'm going to ask anyway.
I have a master/detail form. The detail form has an option to add rows. I have created a dynamic action as defined below...
True Action:
Sequence: 10
Action: Javascript Expression
Fire On Page Load: No
Code: $(this.triggeringElement ).val()
Sequence: 20
Action: SQL Statement
Fire On Page Load: No
Code: select travel_status from territories_summary_v where territory_code=:P3_FIND_COUNTRY_CODE and language='US';
Sequence: 30
Action: Javascript Expression
Fire On Page Load: No
Code: $(this.triggeringElement).closest("tr").find("td[headers='TRAVEL_STATUS_CODE'] input").val($v('P3_FIND_COLOR'));
The P3_FIND_COLOR and P3_FIND_COUNTRY_CODE are defined as hidden fields.
This DA seems to partially work. It will update the travel status code with the proper value for each line. I can see it on screen. But when I apply changes it doesn't save this particular value to the database. If I physically go to the field and type something in, it will save this field. All other values save ok... just not this column .. regardless of the number of detail lines.
Further to this, when I add a row and a new blank row appears, if I change the country, the DA does not fire at all. I've put an alert in on sequence 10 and the alert will fire for a pre-existing row in the table... but not a new row. I would have thought that because it's an onChange DA associated with the country code, it would work for each new row regardless of how many rows are added or whether its a new row vs existing row.
So the first issue is why it won't save the data that is populated in travel status code when I can clearly see it there? Secondly, why this DA is not firing when I add a new row?
If anyone can help me it would be appreciated. I've done a lot of searches but have not come up with much where these issues are concerned.

There is no way to make a good guess on this without an example. It is hard to say what the reason could be.

How to retain value in LoV item in Tabular Form, after Page Refresh

Hi,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, 2nd item(column) in tabular form, that LoV should get populated based on user's selection value in first item LoV.
1. So how do I refer to the value, that user selected in first item's LoV? I will have to use this value as reference in LoV query of my 2nd item ( on this tabular form)
2. Everytime I select value in first item LoV, page gets refreshed, as my requirement is to calculate 2nd item's LoV based on selected value in first item. So after this page refresh, first item LoV loses its value that was selected before the page refresh happened. So how do i retain this value in first item LoV? I have an unconditional process, that on every submit(refresh) of page, I set all my items with their corresponding values. But problem is what do i mention there to refer to this first item ( of type LoV) of tabular form?
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).
Please help.
Thanks and Regards,
Ravi.

Hi Rave,
You will have to use Javascript and Ajax to change the values as ApEx submissions will lose your results unless they are saved into the database.
Remember, that as you are using a tabular form there will be lots of items called f01, fo2, fo3 etc on the page (one per row).
Regards
Michael
