Basing an LOV on another LOV

In a HTML web form, how can I have a LOV (Drop-Down list) based on DEPT, that populates another LOV with all the employees from EMP in the department selected in the first LOV.
I can do it in Javascript but I need to derive my values from tables.
Thanks

Hi,
I dont think you can pass on the table values to a javascript function.
You can definitely use the HTP cartridge functions to display table
data in HTML. There would be a specific HTP or HTF function to build
a form drop down list. I think it's a combination of htp.formSelectOpen
and htp.formSelectOption. Check the documentation here:
http://kontti.helsinki.fi:8889/ows-adoc/psqlwtl9.htm
Populating the EMP LOV should be straight forward unless you are
not looking to change the EMP LOV and DEPT LOV dynamically.

Change LOV of column in view, based on values of another LOV of column in the same view

Hi,
I am using Jdeveloper 11.1.1.5.
I have a scenario in which I have two columns in the view. column names are:
1- Column A
2- Column B
both the columns have LOV's
LOV in column A contains values as: 1, 2. Now, when I select the value 1 in column A, In the column B, an LOV named ABC should be shown. and when I select value 2 from LOV in column A, LOV named XYZ should be shown in column B.
how can I do that?
thanks in advance (^.^).

Use onchange attribute of the first drop-down. On change, submit the form. On server side, fetch the values for second drop-down based on the value selected for the first drop-down.

Set a LOV based on another LOV when the parent value is NULL

Application Express 4.1.1.00.23
Oracle Database 11g
I have two Select Lists (LOV 1 and LOV 2) Items of several other items in a HTML region. LOV 2 is based on value in LOV 1 which is perfectly working. But I need to display some values in LOV 2 when value in LOV 1 is null which is not working at all. Any help is appreciated.
Thanks,

Edit your LOV2 and do the changes suggested below
Cascading LOV Parent Item(s) : LOV1
Optimize Refresh : No (this is important not forget to make it NO)
List of values definition : try to use query similar like this
IF :P2_LOV1 IS NULL THEN
RETURN 'select ENAME as display_value, EMPNO as return_value from EMP';
ELSE
RETURN 'select ENAME as display_value, EMPNO as return_value from EMP where DEPTNO = :P2_LOV1';
END IF;
Hope this will works for you,

Passing parameter from one LOV to another

How can I pass a parameter from one LOV to another so I can restrict the number of recoder of the lower LOV based on what the user have selected in the upper LOV..This is being constructed on the customized page of a report.
Thanks..

If your using release 2, you may have a problem.
A combobox LOV can be used to link 2 LOV's but, the form they are on can't do a query, it fails to return any records. See bug 2141909.
A popup LOV can be used to do a query, BUT, there is a bug when you try to link 2 LOV's. See bug 2505560.
They are trying to do a backport, so submit a tar about it.

How to disable an LOV wrt value in another LOV?

I have a javascript function that works fine if P2_BANK_ASSIGNED is a text item. But if I change it to an LOV is doesn't work. How do I disable an LOV on value of another LOV?



<script type="text/javascript">
function disBankAssigned(){
var lReturn = $x('P2_TRIAL').value;
if (lReturn == 0 ) {
     $x('P2_BANK_ASSIGNED').readOnly = false;
else {
     $x('P2_BANK_ASSIGNED').readOnly = true;

I redeemed a Starbucks gift card for a song --You Found Another Love -- but when I went to play it, I received an error message that the file couldn't be found. Help

I am having a problem getting my Starbucks song to play. I redeemed it in the iTunes store. The song -- You Found Another Love -- shows up in my playlist, but it is not playable because I get an error message that says: File not found.
Anyone have this problem?

Because the location for each song in your library is on your hard drive. If the hard drive isn't there, how can iTunes play it?
You'll have to move/copy the music from your hard drive to your computer's hard drive.
Basically, EASIEST way to do all this, if you don't care about your play counts, etc...
-Delete EVERYTHING from iTunes, so that your library is now empty.
-Go to "Advanced" inside of the "Preferences" window, found in the "Edit" drop-down. You can also access Preferences by pressing Ctrl+, (Press Ctrl and the comma key)
-Change your iTunes Media Folder Location to something simple, but on your computer. I use C:/iTunes. Make sure "Keep iTunes Media Folder Organized" and "Copy files to...." are both checked. You can close Preferences now.
-Now, drag and drop your music from your hard drive into your iTunes library. iTunes will automatically add the music to your library, as you would expect, and also creates a copy of each file to place into that iTunes Media Folder you just created.
Shouldn't have any more problems...

LOV usage -- Can LOV used as key-value pair?

Post Author: phoenix
CA Forum: WebIntelligence Reporting
Hello,
I am using BO XI R2 and I come to an issue with LOV. Can LOV be used as a key-value list?
Say I have a key-value list as below:
A --> 1
B --> 2
Can LOV just list 'A, B.. ' and return 1 if user choose A and 2 if user choose B?
Many thanks.
phoenix

It is possible only if you know all possible KEY values:
with t as (
           select 1 id,'STATUS' key,'TRUE' val from dual union all
           select 1,'AGE GROUP','10' from dual union all
           select 1,'TRAVEL','Y' from dual union all
           select 2,'STATUS','FALSE' from dual union all
           select 2,'AGE GROUP','20' from dual union all
           select 2,'TRAVEL','N' from dual
select id,
        max(case key when 'STATUS' then val end) status,
        max(case key when 'AGE' then val end) age,
        max(case key when 'AGE GROUP' then val end) "AGE GROUP",
        max(case key when 'TRAVEL' then val end) travel
from t
group by id
        ID STATUS AGE   AGE GROUP TRAVEL
         1 TRUE         10        Y
         2 FALSE        20        N
SQL> If you are on 11g, you can use PIVOT construct, but again you need to know resulting columns upfront.
Another thing you could do is to return a CSV list of key all values in one column using STRAGG (or LISTAGG if you are on 11.2), hierarchical queries, XML or undocumented WM_CONCAT.

LOV on an LOV

In Forms, is it possible to have an LOV on an LOV? What I am trying to do is similar to the functionality in the browser
menu. Take for example the File option in the browser menu. Click on File and a list displays, if you mouse-over the
New option another list displays. Is this functionality possible with LOV's in forms? Perhaps another creative way to
accomplish this result?
Thanks

Thanks for your responses.
I have tried using tlist on a List Item and when I run the form I get a default value without a way to bring up a list.
What I did:
I created deptno on a form, I changed the Item Type to List Item. I changed the List Style to Tlist. I created a record
group with a query that I want to use as my list. I created a when-new-form-instance trigger with the following
DECLARE
Error_Flag Number;
BEGIN
Error_Flag := POPULATE_GROUP('ListGroup');
IF Error_Flag = 0 THEN
POPULATE_LIST('DEPTNO', 'ListGroup');
ELSE
MESSAGE('Error while populating list group');
END IF;
END;
I do this to build a dynamic list. When I run the form I get a default value (first item of the record group) in the deptno
field without a way to pick another value. If I change the List Style to Poplist I can then pick from the list the department I
want.
I am still not sure how changing to a list item (tlist) is going to solve the problem. Now I need a list on a list.
What I am trying to do is provide the user with two lists on one field similar to the File/New menu option in the browser
menu. I have a field called CR_TYPE, when I click for list I want them to see a list of Types, when they bring the mouse
over or highlight a type I want to bring up a list to the right of the current list with a list of the subtypes for that type.
Is it possible with forms? Examples would be a tremendous help.
Thanks

How to display data from a recordset based on data from another recordset

How to display data from a recordset based on data from
another recordset.
What I would like to do is as follows:
I have a fantasy hockey league website. For each team I have
a team page (clubhouse) which is generated using PHP/MySQL. The one
area I would like to clean up is the displaying of the divisional
standings on the right side. As of right now, I use a URL variable
(division = id2) to grab the needed data, which works ok. What I
want to do is clean up the url abit.
So far the url is
clubhouse.php?team=Wings&id=DET&id2=Pacific, in the end all
I want is clubhouse.php?team=Wings.
I have a separate table, that has the teams entire
information (full team name, short team, abbreviation, conference,
division, etc. so I was thinking if I could somehow do this:
Recordset Team Info is filtered using URL variable team
(short team). Based on what team equals, it would then insert this
variable into the Divisional Standings recordset.
So example: If I type in clubhouse.php?team=Wings, the Team
Info recordset would bring up the Pacific division. Then 'Pacific'
would be inserted into the Divisional Standings recordset to
display the Pacific Division Standings.
Basically I want this
SELECT *
FROM standings
WHERE division = <teaminfo.division>
ORDER BY pts DESC
Could someone help me, thank you.

Assuming two tables- teamtable and standings:
teamtable - which has entire info about the team and has a
field called
"div" which has the division name say "pacific" and you want
to use this
name to get corresponding details from the other table.
standings - which has a field called "division" which you
want to use to
give the standings
SELECT * FROM standings AS st, teamtable AS t
WHERE st.division = t.div
ORDER BY pts DESC
Instead of * you could be specific on what fields you want to
select ..
something like
SELECT st.id AS id, st.position AS position, st.teamname AS
team
You cannot lose until you give up !!!

How to create a new row for a VO based on values from another VO?

Hi, experts.
in jdev 11.1.2.3,
How to create a new row for VO1 based on values from another VO2 in the same page?
and in my use case it's preferable to do this from the UI rather than from business logic layer(EO).
Also I have read Frank Nimphius' following blog,but in his example the source VO and the destination VO are the same.
How-to declaratively create new table rows based on existing row content (20-NOV-2008)
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/13-create-with-params-169140.pdf
I have tried:
1.VO1(id,amount,remark1) and VO2(id,amount,remark2) are based on different EO,but render in same page,
2.Drag and drop a Createwithparams button for VO1(id,amount,remark),
3.add: Create insertinside Createwithparams->Nameddata(amount),
4.set NDName:amount, NDValue:#{bindings.VO2.children.Amount}, NDtype:oracle.jbo.domain.Number.
On running,when press button Createwithparams, cannot create a new row for VO1, and get error msg:
<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: For input string: "Amount"
java.lang.NumberFormatException: For input string: "Amount"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
Can anyone give some suggestions?
Thanks in advance.

Hi,CM,
I'm really very appreciated for your quick reply! You know, today is Saturday, it's not a day for everyone at work.
My principal requirement is as follows:
1.select/check some rows from VO2, and for each selection create a new row with some attributes from VO2 as default values for VO1's corresponding attributes, and during this process the user may be cancel/uncheck or redo some of the selections.
--so it's better to implement it in UI rather than in EO.
2.it's better to implement this function with declarative way as in Frank Nimphius' blog.
--little Jave/JS coding, the better. I only have experience in ORACLE FORMS, little experience in JAVA/JS.
In order to get full information for the requirements of my use case, can take a check at:
How to set default value for a VO query bind variable in a jspx page?
(the end half of the thread: I have a more realworld requirement similar to the above requirement is:
Manage bank transactions for clients. and give invoices to clients according to their transaction records. One invoice can contain one or many transactions records. and one transaction records can be split into many invoices.

Can I assign a task based on information from another column?

For example:
Let's say I have a column called "Question Type" and this column has multiple checkbox choice, those being:
     Math
     Science
     History
     English
     Other
I want to allow users to be able to select multpile catagories for the question, like making one both math and science (which right now is completely possible)
I then want another column that says who the problem is assigned to. Bob is good at math, Joe at science, Jill at histroy, Jenn at English, and Billy handles everything else.
1) Is there a way that the task can be automatically assigned to my math expert Bob when I specify that the item I am adding is a math problem?
2) If I make a problem both math and science, can the task be assigned to both Bob and Joe?
Thanks in advance!

Hi,
According to your post, my understanding is that you wanted to assign a task based on information from another column.
To assign task to multiple users, you need to:
Create a workflow and add action: Start Approval Process.
Click these user, select the Group, change One or a time(serial) to
All at onec(paralle).
Right click the action, select Properties, click ExpandGroups, change No to
Yes.
Then you can assign task to each member of the group.
I recommend to follow the steps as below to achieve what you want:
Create a custom list, add columns: Question Type(Choice); Assigned to(Person or Group).
Create a workflow associated the list.
Add conditions and action as below:
Then the task can be automatically assigned to 123 when the item is a math problem.
In addition, if you make a problem both math and science, the task can be assigned to both 456 and 789.
You can add other conditions to satisfy all the requirements.

ADF LOV and Cascading LOV in JDeveloper 11.1.1.5.0 Issue

Hi,
I have created business component ExpenseHdrView and added LOV and Cascaded LOV. If I run the application module I could see the LOV is working. It is displaying list of values and Return value(id value is not dispalyed as expected). But when I include the view in an ADF form then LOV is working but in the form when I select any value it is displaying the corresponding ID value. This is not in sync with business component.
I am new to this ADF world. Am I doing anything wrong or missing something?
Please help.
Thanks,

Hi Kalpesh,

Filter based upon results of another request

How do I troubleshoot a Filter based upon results of another request issue?
I have a report that lists every account that purchased a product in May.
I have a report that lists every account that purchased a product between Jan - April.
I have a report that lists every account that purchased a product in May and also between Jan-apr. The problem is it's returning Account Names that are valid for May but not for Jan-apr and I dont' know why. It filters some but not others, interestingly enough it seems to split it down the middle.
Report A = 222 customers
Report B = 673
Report C = 111???
When I compare A to B manually I get 94.
Any ideas as to how I troubleshoot this?

Worked it out ;-D

How to change the values in an LOV based on values selected in another LOV

Hi,
I have a requirement in ADF where there are two LOVs. Based on the values that I select in the 1st LOV, the values in the second LOV should change dynamically.
Also, the 1st LOV accepts 3 values, for every value I select, a different query is executed to populate the 2nd LOV.
I have a rough thought that I can use 3 different read only view objects containing these 3 queries. And based on the value I select in the 1st LOV I can execute the corresponding View object from the backing bean. But my doubt is how to link the results of that query that is executed to populate the 2nd LOV.
Thanks in advance.
Edited by: 886591 on Sep 21, 2011 4:48 AM

Hi Brisk,
Thanks for your reply.
The link that you have provided explains how to disable and enable the other LOVs based on a parent LOV. But in my case there are two Select One Choice fields i.e. the dropdowns (sorry that I addressed it as LOV in my previous post which might be confusing). There are 3 static values in the parent dropdown where each of them are associated with a different query. for e.g if the three values in the drop down are A, B and C; if i select A, then query associated to A should be executed ; if i select B, then query associated to B should be executed and if I select C, query associated to C should be executed. Then the output attribute of that query should be populated in the child dropdown.
Please let me know about the solutions to this.
Thanks,
Kavitha
