Bug in Static LOV definition in tabular form?

I have always defined static LOVs as follows
STATIC:Yes;Y,No;N
but now with V4.0+ the select list at runtime appears as follows:
STATIC:Yes
No
Suddenly the literal "STATIC" is appearing in the first display field.
If I omit the word "STATIC:" from the definition, it seems to work fine. Was this an intentional change in the definition of static LOVs? If so, you then the developers need to update the help text for LOVs.

Bug Report: Static LOV's and PDF Printing with Tabular Forms

I have a tabular form, which acts as an editable report. Some columns are 'Standard Report Column' and some are Select Lists, using Static LOV's with the contents of
Yes;Y,No;NThe purpose of the page is to allow users to edit yes/no attributes of a row. Then, they can print the report.
To make the current sort of the report reflect what is being printed to PDF, I've used a Report Layout associated with the report region, as oposed to a report query. A report query in this case would not reflect the sort of the report (all columns are sortable asc/desc).
Anyway, I link my report with the layout created, and go to run it. I get this message.
ORA-06550: line 1, column 50: PLS-00103: Encountered the symbol "," when expecting one of the following: := . ( @ % ; The symbol ":= was inserted before "," to continue.
     Error      ERR-1000 Unable to determine LOV from "declare function x return varchar2 is begin Yes;Y,No;N return null; end; begin wwv_flow_utilities.g_query := x; end;".
OK
report error:
ORA-20001: Error fetching column value: ORA-01403: no data foundI'm guessing the product is trying to take my static LOV and place it in a function to be able to generate which value is being displayed as text, from the select lists. However, it doesn't work.
I've been able to get around it - by adding a YES_NO domain to my domain_codes table (a table which associates abreviations with full meanings), I can set by select lists to be query based select lists using the SQL select code_meaning, code from domain_codes where domain = 'YES_NO_CODE'. This still allows the user to dropdown Yes/No fields, and the PDF printing doesn't break.
It is just me, or can't the PDF printing handle static LOV's in tabular forms/reports?

Hi Patrick.
I've tried STATIC:Yes;Y,No;Nwhile stating it is a Select List (static LOV). The values that are rendered on the page are
[STATIC:Yes]
[No        ]
----------I tried the same thing with STATIC2 instead of STATIC, and the same thing happened.
It also broke if I tried STATIC or STATIC2 under Select List (query based LOV). This is within a report where there is no hyperlink to say 'Create/Edit static list' or 'Create Dynamic List', as there is under select list items.
However, I am finding that for some reason, the values being sent to the PDF are not the values in the database (Y/N), but the showing values (Yes/No). This happens when I use the domain_code select query as the query based LOV.
Furthermore, I cannot get any columns not rendering on the page to be generated in the PDF. I have a column that groups items depending on values, and I want this grouping to display in the PDF instead on the original value, ideally.
Cheers,
K.

Dynamic LOV in a Tabular Form

Can somebody please tell me if there is a easy way to code a
dynamic LOV in a Tabular Form?
I need the ability to access a column value in the table row, to use in the WHERE clause of LOV query for another column in the row? Seems
like that should be easy , but not finding an answer.
Thanks for any help.
Carol

Hi Carol,
You can add the select list's definition directly into your SQL statement using APEX_ITEM.SELECT_LIST_FROM_QUERY - see: [http://download.oracle.com/docs/cd/E10513_01/doc/apirefs.310/e12855/apex_item.htm#CHDIDGDA]
If you first run your page with your existing select list on it, then do a View Source and look for the select list, you will see a "name" attribute of something like "f01" or "f02" etc. Make a note of the number part of this.
Then update your SQL statement to include the above and using the number you noted as the Index value (say, 4):
SELECT EMPNO,
ENAME,
DEPTNO,
APEX_ITEM.SELECT_LIST_FROM_QUERY(4,MGR,'SELECT ENAME d, EMPNO r FROM EMP WHERE DEPTNO = ' || DEPTNO || ' AND EMPNO <> ' || EMPNO) MGR
FROM EMPThat would give you a select list of employees in the same department as the current employee (excluding that employee themself)

Why doesn't a Popup Key LOV (named LOV) in a tabular form not display values in the popup?

I have a tabular form and I'm setting one of the fields to a Popup Key LOV (named LOV). The named LOV is a static LOV. When the popup is displayed there are no values displayed. The same thing happens if I use a Popup LOV (named LOV).
I created a sample application http://apex.oracle.com/pls/apex/f?p=15762:1that shows what happens. When the job field popup is selected, no items are displayed. If I change the item to a Select List (named LOV) it works fine.
Is this a bug?

Hi
I am also getting the same issue. Hope it could be a bug.
Can anyone plz confirm this?
Thanks

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

Specify image for a pop-up LOV in a tabular form?

Hi,
I am using a tabular form for users to edit data. One of the fields has too many options to use a select list, so I have to use a pop-up lov (query based)... grrrr
The lov shows up in my form as [Field value]List
I would like to remove the text "List" and put a small icon there. Where can I specify the image source?
Thanks,
Rob

Hi Denes,
Thanks for your reply. I looked at your page, but I'm not sure if it relates to my issue.
Here's a piece of the generated HTML for the pop-up lov:
<span class="lov">
<label class="hideMe508" for="f03_0004">f03_0004</label>
<input id="f03_0004" type="text" value="U41" maxlength="2000" size="8" name="f03"/>
<img align="middle" style="vertical-align: middle; cursor: pointer;" alt="List"/>
</span>Notice that there is an image tag, but the src attribute is not there...as a result the browser displays the alt text List.
If I missed your solution I apologise...

Cascading LOV in a Tabular form

Hi Guys,
I have read numerous articles on the generation of cascading LOV's in a tabular form but havent been able to get it working
I have created an example in my apex workspace at:
http://apex.oracle.com/pls/apex/f?p=4000:1500
workspace XXAPPS
Username guest
Password demo
app no 17551
Page 2
In my test scenario, I have an emp table, dept table and an office table.
Within my tabular form(based on the emp table), I have a deptno column and an office column.
Depending on what the user selects in the deptno column, I would like the corresponding list of offices associated to that dept LOV to be returned in the offices LOV.
The table structure is
EMP
EMPNO
ENAME
JOB
MGR
HIREDATE
SAL
COMM
DEPTNO
OFFICE_ID
DEPT
DEPTNO
DNAME
LOC
OFFICE
OFFICE_ID
OFFICE_NAME
DEPTNO
When the user selects a deptno in the LOV I would like that to control the values that are returned in the office LOV.
I have used Jari's blog post:
http://dbswh.webhop.net/dbswh/f?p=BLOG:READ:0::::ARTICLE:2003800346210117
but as you can see it isn't quite working in that the office LOV is not returning anything.
I am pretty new new to JavaScript and jQuery so am no doubt doing something wrong as some of the steps are causing errors and are confusing me a bit e.g. step2 is causing the page to return blank (I have commented the code out in the example)
Any help would be greatly appreciated.
Thanks

Hi fac,
That is the full code as per the Jari's link on http://dbswh.webhop.net/dbswh/f?p=BLOG:READ:0::::ARTICLE:2003800346210117 (last but one section of instructions).
I have got the id of the elements (f07 and f06) by using IE Developer toolbar and have passed those into the dynamic action.
The child element is now just showing loading...
It seems to me that the on demand process is not being called because I changed the code to:
DECLARE
l_sql VARCHAR2(32700);
BEGIN
IF APEX_APPLICATION.G_x01 IS NOT NULL OR APEX_APPLICATION.G_x01 IS NULL
THEN raise_application_error(-20001,'code gets here');
l_sql := 'SELECT competency_id AS RET
,competency_description AS DIS
FROM XXMEL_FOCUS_COMPETENTCIES
WHERE competency_category_id = ' || APEX_APPLICATION.G_x01 || '
ORDER BY competency_description
APEX_UTIL.JSON_FROM_SQL(l_sql);
ELSE
HTP.prn('{"row":[]}');
END IF;
just to see if the code is getting to the process but the error message that I put in the PL/SQL is not firing.

STATIC vs STATIC2 in static LOV definition

Hi All,
what is the difference between STATIC and STATIC2 ?
The documentation on creating checkbox references word 'STATIC'. When I create static LOV by clicking 'Create or edit static List of Values' link on 'Edit Page Item' this uses word 'STATIC2' in LOV definition.

One sorts values alphabetically and the other in the order in which they are written.

Restricting LOV values in tabular form

Hi,
I am new to APEX.
I have a tabular updateable report with the following layout
wagon_no container_no origination destination received_flag wagon_size
wagon123 container123 MLPM DOZ N 20
wagon456 container456 MLPM DOZ N 40
Wagon number,container_number,origination,destination are LOV's and which can be updateable.
Size is read only.
I need to restrict the entry of the wagon's and container in the report.
ie,If wagon Size is 20,then I can enter the same wagon size twice.
If the wagon size is 40,then I can enter the wagon only once for a particular train.
Can it be done at the LOV?
Can it be done through Javascripts..if yes,how can it be done??I have not used Javascript..
Also,the container cannot be entered twice..
I tried restricting the container number in the LOV by not displaying the entered container number in the LOV .But,once saved and while querying later,it doesnot show the correct value.
Can anybody help me out?please,its quite urgent..

Hi,
Have a look at Denie' example on cascading LOV's. this should give you some insight.

Also does it make a difference if the temporary item (condition) is a string value rather than a numeric value?
Thanks a lot!

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.

HTMLDB 2.0 bug - tabular forms - select list from named LOV

Hi!
Changing a column in a tabular form to 'select list (named lov)' gets the following error in HTMLDB 2.0 when you try to add a row (to an empty table in my case):
PL/SQL error at column 133.
Create a table and then create a tabular form on it. Then change a report column to be a 'select list (named lov)'. Save and run the form and the error occurs.
Thanks!

Tabular form LOV's not populating correctly on edit from report

My form has four LOV's and several text fields. Two of the LOV's will not populate (contains null value) from the report when i try to edit the row, however the other two Lov's populate correctly. Any ideas why i can't get the lov's to populate with the correct value from the report?
each LOV is set to display null value as -- choose value -- with no return value. when i click edit from the report the form (page 2) comes up with the corresponding values from the report, but as i stated two of the LOV's contain -- choose value -- instead of the correct value from the corresponding reports row. All four LOV's items are set exactly the same 2 being static and 2 dynamic; one of each not populating right.
any help would be greatly appreciated.

Hi
I've not used popup lovs in tabular forms for a few years now, but if your using the apex_item's to generate your tab form then I think you need to allow an idx number for the pass back value. e.g. (I have left idx value 2 for the pass back value)
SELECT
APEX_ITEM.POPUPKEY_FROM_LOV (1,deptno,'DEPT') dt,
APEX_HIDDEN(3, EMPNO) en
FROM emp
I hope that helps

Tabular form - Different LOV for different rows

In a tabular form column, is it possible to have a select list whose values depend on some other column in the row? There doesn't appear to be a way to use #COL# notation to refer to current row values in the LOV query definition.
Ideas? Thanks

Hi Scott,
Thanks ..I formed some idea about APEX_UTIL.KEYVAL_NUM. I have a problem where I am not able to decide if I can make use of this package and solve..
Can you please have a look at this thread.. Re: Tabular form - Different LOV for different rows
I have a SQL which populates a tabular form on the page.Coulmn1 some text, Column 2 is to show a drop down as YES and NO. i am trying to freeze the option for rows 2,3,4 as NO, if the Option choosen in first is NO.
So, what I am trying to ask is..can I save my first selection in a global variable and use it in where clause of [select list query] the second drop down..Not sure how I can do this..Appreciate if you can show me a direction.
Thanks,
Chaitu.

How to refresh page after selecting value from LOV item , in a tabular form

Hi ,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, couple of issues here.
1.
2nd item(column) in tabular form, that LoV should get populated based user's selection value in first item LoV. So how do i refer to the value, that user selected in first item's LoV? I will have to use this reference in LoV query of my 2nd item ( on this tabular form)
2.
How can we refresh the page, when user selectes value in first item ( from LoV). As this is a tabular form, here item type is Select List, we dont have an option to pick item type as Select List with Submit. So problem is that when user selects value for item 1, refresh does not happen and item 2 LoV does not get populated as per user's selection in item 1.
Please help here. Would be really appreciated.
Thanks and Regards,
Rave.

Thanks Ben and Dan for your responses.
Ben, your solution helped me with refresh of page, as page got submitted.
This answers to my 2nd question. However, I still need to know first question, which basically is, how do i refer to the value, that user selected in first item LoV.
Issue is, I selected the value in first item LoV, it got submitted and page fot refreshed. But after page refresh, first item LoV loses its value that I had selected last time. It does not retain the selected value after refresh.
I have an unconditional process, that on every submit(refresh) of page, I set my items with their corresponding values. But problem is what do i mention there to refer to this item.
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).
Any help here would be really appreciated. Please suggest how do we refer to this item's selected value.
Thanks and Regards,
Ravi.
