Disable Values from Relationship LOVs

Hi,
I would like to disable certain seeded values from the Lookup CONTACT
For ex. I want to disable the value "Friend" from CONTACT
If I try to uncheck the Enable flag, It says the field is protected against update.
Can somebody provide a solution for this.
Thanks in Advance.
Ben

It actually depends on what you need.
If you have multiple localizations(locs) implemented in your Org, then un-checking the Enabled field, will not show the value for any of the locs.
In which case you can use the Tag field, to work out according to your installed locs.
If there is only 1 loc you're interested in, then both are the same.
One small thing though -
If the created_by is : 1 (AUTOINSTALL) or 2(INITIAL SETUP)
then the system is not allowing you to change the Tag filed for the record from the UI(you can use Diagnostics -> Examine to change it)
If the created_by is : 120(ORACLE12.0.0)
then you can change the Tag, Enabled flag from the UI.
So this might be a bug on the Lookup screen.
You can check with Oracle and log a bug.
Also, when you change values from Diagnostics -> Examine, just check what happens if you re-apply a patch or hrglobal.drv.
If the patch is overwriting your modified values, then it might be an issue. You might have to change these every-time a patch is applied.
Cheers,
VB

[UIX] How To: Return multiple values from a LOV

Hi gang
I've been receiving a number of queries via email on how to return multiple items from a LOV using UIX thanks to earlier posts of mine on OTN. I'm unfortunately aware my previous posts on this are not that clear thanks to the nature of the forums Q&A type approach. So I thought I'd write one clear post, and then direct any queries to it from now on to save me time.
Following is my solution to this problem. Please note it's just one method of many in skinning a cat. It's my understanding via chatting to Oracle employees that LOVs are to be changed in a future release of JDeveloper to be more like Oracle Forms LOVs, so my skinning skills may be rather bloody & crude very soon (already?).
I'll base my example on the hr schema supplied with the standard RDBMS install.
Say we have an UIX input-form screen to modify an employees record. The employees record has a department_id field and a fk to the departments table. Our requirement is to build a LOV for the department_id field such that we can link the employees record to any department_id in the database. In turn we want the department_name shown on the employees input form, so this must be returned via the LOV too.
To meet this requirement follow these steps:
1) In your ADF BC model project, create 2 EOs for employees and departments.
2) Also in your model, create 2 VOs for the same EOs.
3) Open your employees VO and create a new attribute DepartmentName. Check selected in query. In expressions type (SELECT dept.department_name FROM departments dept WHERE dept.department_id = employees.department_id). Check Updateable always.
4) Create a new empty UIX page in your ViewController project called editEmployees.uix.
5) From the data control palette, drag and drop EmployeesView1 as an input-form. Notice that the new field DepartmentName is also included in the input-form.
6) As the DepartmentName will be populated either from querying existing employees records, or via the LOV, disable the field as the user should not have the ability to edit it.
7) Select the DepartmentId field and delete it. In the UI Model window delete the DepartmentId binding.
8) From the data controls palette, drag and drop the DepartmentId field as a messageLovInput onto your page. Note in your application navigator a new UIX page lovWindow0.uix (or similar) has been created for you.
9) While the lovWindow0.uix is still in italics (before you save it), rename the file to departmentsLov.uix.
10) Back in your editEmployees.uix page, your messageLovInput source will look like the following:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="${bindings.DepartmentId.path}"
    destination="lovWindow0.uix"/>Change it to be:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="DepartmentId"
    destination="departmentsLov.uix"
    partialRenderMode="multiple"
    partialTargets="_uixState DepartmentName"/>11) Also change your DepartmentName source to look like the following:
<messageTextInput
    id=DepartmentName
    model="${bindings.DepartmentName}"
    columns="10"
    disabled="true"/>12) Open your departmentsLov.uix page.
13) In the data control palette, drag and drop the DepartmentId field of the DepartmentView1 as a LovTable into the Results area on your page.
14) Notice in the UI Model window that the 3 binding controls have been created for you, an iterator, a range and a binding for DepartmentId.
15) Right click on the DepartmentsLovUIModel node in the UI Model window, then create binding, display, and finally attribute. The attribute binding editor will pop up. In the select-an-iterator drop down select the DepartmentsView1Iterator. Now select DepartmentName in the attribute list and then the ok button.
16) Note in the UI Model you now have a new binding called DCDefaultControl. Select this, and in the property palette change the Id to DepartmentName.
17) View the LOV pages source, and change the lovUpdate event as follows:
<event name="lovSelect">
    <compound>
        <set value="${bindings.DepartmentId.inputValue}" target="${sessionScope}" property="MyAppDepartmentId" />
        <set value="${bindings.DepartmentName.inputValue}" target="${sessionScope}" property="MyAppDepartmentName" />
    </compound>
</event>18) Return to editEmployees.uix source, and modify the lovUpdate event to look as follows:
<event name="lovUpdate">
    <compound>
        <set value="${sessionScope.MyAppDepartmentId}" target="${bindings.DepartmentId}" property="inputValue"/>
        <set value="${sessionScope.MyAppDepartmentName}" target="${bindings.DepartmentName}" property="inputValue"/>
    </compound>
</event>Thats it. Now when you select a value in your LOV, it will return 2 (multiple!) values.
A couple things to note:
1) In the messageLovInput id field we dont use the .path notation. This is mechanism for returning 1 value from the LOV and is useless for us.
2) Again in the messageLovInput we supply _uixState as an entry in the partialTargets.
3) We are relying on partial-page-refresh functionality to update multiple items on the screen.
Im not going to take the time out to explain these 3 points, but its worthwhile you learning more about them, especially the last 2, as a separate exercise.
One other useful thing to do is, in your messageLovInput, include as a last entry in the partialTargets list MessageBox. In turn locate the messageBox control on your page (if any), and supply an id=MessageBox. This will allow the LOV to place any errors raised in the MessageBox and show them to the user.
I hope this works for you :)
Cheers,
CM.

Thanks Chris,
It took me some time to find the information I needed, how to use return multiple values from a LOV popup window, then I found your post and all problems were solved. Its working perfectly, well, almost perfectly.
Im always fighting with ADF-UIX, it never does the thing that I expect it to do, I guess its because I have a hard time letting go of the total control you have as a developer and let the framework take care of a few things.
Anyway, I'm using your example to fill 5 fields at once, one of the fields being a messageChoice (a list with countries) with a LOV to a lookup table (id , country).
I return the countryId from the popup LOV window, that works great, but it doesn't set the correct value in my messageChoice . I think its because its using the CountryId for the listbox index.
So how can I select the correct value inside my messageChoice? Come to think of it, I dont realy think its LOV related...
Can someone help me out out here?
Kind regards

Bold value from popup LOV

Hi,
style="font-weight:bold" or class="fielddatabold" in the element's HTML Form Element Attributes work perfectly for the text field. I cannot get the same result for field with disp.value from popup LOV (display value,return key). I can change font family for example, but cannot bold. Any suggestions ?

Thanks a lot for your answer. I got the same idea, but cannot see any place to manage returned values on this template. Description from pop-up key LOV seems to be turned "disabled", and will get the grey colour on the screen. However, if I will change to Select list, it looks fine.

Two values from a LOV to Timecard LDT

Hi,
I have a requirement to pull two values from single LOV to Timecard layout page.
e.g.: Suppose we have a LOV field 'emp_number' on layout and this field is getting value from one LOV. Query in LOV shows emp_number and emp_last_name. I want to put one more field on layout page by the name Last_Name and whenever a emp_number value is selected in LOV, corresponding emp_last_name value should be coming to Last_Name field of layout page. Can somebody please help me on how to do this?
I have tried to add one similar HXC_LAYOUT_COMPONENTS as of Emp_number LOV field to ldt file with component = 'Text_Field' but it is not working for me :(

Follow this note 307151.1, this note describes how to populate a Task Name in a different field when Task number is selected in LOV, you have a similar requirement, so you can configure the attributes as described in that note.

Returning a value from a LOV to the main document

Hi,
I'm using jheadsrart with uix, I have a form with a LOV. When I chose a value in the LOV, I need to return another value from that LOV to a hidden field in my main document.
How can I do that?
Thanks for your help!
Martin

Hi Rohit,
Just declare the two variables var1(variable for checking data) & var2(variable for counter) in your include program.
Inside the include you can do the coding as under:
IF VAR1 <condition for checking data>.
VAR2 = VAR2 + 1.
ENDIF.
Now you can check the value of the variable VAR2 in the main program & call the desired function.
Regards,
Chetan.

How do I pass selected values from dynamic LOV to Command SQL in Oracle

My environment:
Crystal 11
Oracle 10
I've created and tuned a SQL script for a report. In the Database Expert, I've copied the SQL into a Command. I've modified the Command to create 3 parameters.
I need help with the following:
1) How do I create a dynamic, cascading LOV and associated prompt group for the three parameters defined in the Command?
2) How do I pass the user selected valueS from the prompt group into the Command SQL as limits applied to the query executed against the database?

I have the same problem with same environment .
The main report is having a 2 level cascading dynamic parameters.
I created a sub report with a command as below.
*select * from (*
select DATUM,MSEC,CNT,B1_NAME,B2_NAME,B3_NAME,ELEM_NAME,INFO_NAME,m.INFOTYPE,V.NAME,rank()
over (partition by B1_NAME,B2_NAME,B3_NAME order by DATUM desc ,MSEC desc,CNT desc) currentRank
from MESSAGES m,INTYDE i,VANAME v
where DATUM <=SYSDATE and trim(B1_NAME)='{?B1Name}'
and trim(B2_NAME)='{?B2Name}'
and m.INFOTYPE=i.INFOTYPE
and i.VALUE_NAME_NUMBER = v.VALNUM) where currentRank=1
I needs to pass cmbination of B1Name and B2Name from main report. I created a formula like
formula=Join({?B1Name},{?B2Name}),'|'); But this is showing some error.
and How I will substitute this in my command . As I new to Crystal XI help expected.

How to create a multi column list item and select these values from a LOV

Hi all,
My requirements are:
1) create an LOV which holds the productno, productname and productprice fields (this is working)
2) at run time, select one record from LOV and populate the list/grid with this selected record values of productno, productname and productprice fields, so we are showing them on the form in the form of a table/grid (not working)
3) be able to select multiple records from LOV and be able to populate the list item with multiple records (not working)
4) have two more columns in the list/grid, for productquatity and total price (not wokring)
Please help me.
how can i create this grid or list in oracle
whats the possible way of acheiving this in oracle

If you use a list item to display multiple columns then you'll need to use a fixed-width font. You can achieve a similar look with proportional fonts by using a normal block and setting the fields' bevel to 'None'.
Each column in the LOV has a Return Item property (under Column Mapping Properties). Set this to a :block.item reference for each column to bring the data back into those referenced fields.
You can't select multiple records from an LOV. For this you will need to create your own form. Check the help for system.mouse_button_modifiers to see how to respond to Ctrl+click and Shift+click.
To add columns just modify the LOV's record group's query.

Return multiple values from dynamic lov in apex 3.2.1

Hi
I need to create a dynamic lov that displays multiple values from a table and RETURNS multiple values into display only fields in a form page to be saved to the database
For example
dynamic list of value name SERVER
select name || ',' || life_cycle d, name r
from sserver
order by 1
This SERVER LOV is attached to the P4_SSERVER_NAME field in the form.
However this only returns sserver. name into the P4_SSERVER_NAME field in the form. I would need to capture the life_cycle field as well and populate the P4_LIFE_CYCLE field in the form as well. How does one do this?
I have searched this forum however could not find a thread that fit my situation. i saw that in 4.2 there is dynamic action however unable to upgrade at this moment.
any suggestions are greatly appreciated.
thank you

Hi CRL,
One method is to set the value of your P4_LIFE_CYCLE item via APEX_UTIL.set_session_state
To do this you need to create a Page Process
Type PL/SQL anonymous block
Process Point On Load - Before Header
The source for the Process might look like this: DECLARE
   l_life_cycle   VARCHAR2 (50);
BEGIN
   SELECT life_cycle
     INTO l_life_cycle
     FROM sserver
    WHERE :p4_sserver_name = sserver.name;
   APEX_UTIL.set_session_state ('P4_LIFE_CYCLE', l_life_cycle);
END;Jeff

Better display values from shuttle LOV in a report

Hi,
I have created a shuttle LOV in a form and then a report that shows (among other things) the values chosen from this shuttle LOV.
If the user choose more than one value I don't like how they get displayed in the report (they have to go into a single cell) because
the user sees a list of items separated by ":" .
Is there a simple way to show them for example as a bullet point list or in some other nicer human readable format?
Thanks,
Antonella

Hi user13140530,
*1. I think you have colon separated data in your database.*
//create one function
create or replace function DISPLAY_FORMAT
    (L_ID in NUMBER)
    return VARCHAR2 is
v_selected APEX_APPLICATION_GLOBAL.VC_ARR2;
val_list varchar2(4000) := '';
val_list1 varchar2(4000) := '';
begin
SELECT SHUTTLE_VALUE INTO val_list FROM YOUR_TABLE WHERE ID = L_ID;     // select shuttle value according to your table structure.
v_selected := APEX_UTIL.STRING_TO_TABLE(val_list);
FOR i IN 1..v_selected.count
LOOP
    val_list1 := val_list1||i||'.'||v_selected(i)|| '<br>';
END LOOP;
RETURN val_list1;
end;
/*2. call the above function in your report as a column.*
// suppose this is your report query
select ID, NAME, DISPLAY_FORMAT(ID) from your table_name;Try the above code,hope this may helps you.

Error while selecting NULL value from Popup Key LOV(numeric or value error)

Hi,
I have a item P1_DEPTNO with following properties.
P1_DEPTNO - Popup Key LOV (Displays description, returns key value)
LOV - P1_DEPT_LOV
select deptname d, deptno r from deptP1_DEPTNO item properties
List of Values
Named LOV - P1_DEPT_LOV
Display Null - Yes // changed to Yes, so that it can accept NULL values.
Null display value - NULL
Null return value -   (blank)PL\SQL Process -
declare
v1 number;
begin
if :P1_DEPTNO is null OR :P1_DEPTNO = '' then
    v1 := 0;
else
    v1 := :P1_DEPTNO;
end if;
// rest of the PL\SQL process
end;Now, when I run the page and select NULL value from Popup LOV and submit, I get the following error.
ORA-06502: PL/SQL: numeric or value error: character to number conversion error.When, I select any other value other than NULL, then it's working perfectly fine.
Only in case of NULL value, I am getting this error.
ANY idea, why this error is coming??
Thanks,
Deepak

Hi Varad,
I did the following change
Null display value - (blank) // by default it is displaying '%' in the select this
Null return value - -1
but when I select % (null value) from the popup list, it displays the return value -1 in the text field.
My question is why it is displaying the return value -1 in the text field...*It should display the display value in the text field (i.e blank in this case)*
then, I did the following change
Null display value - (blank) // by default it is displaying '%' in the select this
Null return value - // a single space, so that when I select %(null value) from the list, it should display blank in the text field...
then I did the following change in the PL\SQL process.
PL\SQL process
declare
v1 number;
begin
if :P1_DEPTNO = ' ' then // -- checking the value of single space ' ' when we select %(null) in the popup list, BUT even I select %(null), control is not coming here.
    v1 := 0;
else
    v1 := :P1_DEPTNO;
end if;
// rest of the PL\SQL process
end;Thanks,
Deepak

ADF-UIX- How to populate multiple input fields from an lov?

Like in Forms Developer where using an LOV we can populate multiple tex input items on selection of a value from the LOV, is it possible for us to do the same in ADF UIX.
Iam usiing JDeveloper 10.1.2

Have a look at this previous post:
Re: Can return messageLovinput more than one value?

Error when submitting NULL from a LOV

Hello!
I searched the forum and couldn't find a matching thread.
While using APEX 3.01 I have problems while submitting a NULL-value from a LOV to a function, which expects a number.
The error-msg is : "ORA-06502: PL/SQL: numeric or value error: character to number conversion error"
NullValue: NULL
I can't use a workaround like using -1 instead of NULL, because of constraints.
Thanks!
Max

Hello,
I'm confused....you're selecting something from an LOV and passing that to a function correct?
You can't pass NULL as you're getting the error, but if you 'hardcode' a value like -1 it won't work due to your constraints correct?
So....the question is...what do you want it to submit instead of NULL/-1 ?

How to get actual value from LOV list

Like Subject says: How to get actual value from LOV list. Any help will be appreciated.
Thanks.

Thanks Shay, I did it with bind variable because I'm not using JSF. Is there any chance to post solution using standard JSTL or HTML expression. I have something like this: LOV displays some Companies names:
<html:select property="UserJobCompanyId"
                         disabled="${!bindings[\'UserJobCompanyId\'].updateable}"
                         onchange="submitform();">
              <html:optionsCollection label="prompt" value="index" property="UserJobCompanyId.displayData"/>
            </html:select>and I want to get CompanyID of selected Company.
Thanks, again.
