Multi-Select LOV with multiple return columns

Hi,
I'm wondering if it's possible (and how) to return more columns from the LOV page the calling page. Default only 1 column is displayed in the LOV and 1 column is returned.
However it's easy to display an additional column in the LOV: Just copy the column tag change the binding column to display and change the prompt.
Furthermore in my situation I don't have a FK between the calling page and LOV. It's just a LOV which returns values which can be edited after.
Regards,
Marcel

Marcel,
In the upcoming release it will be possible to supply a comma-separated list in the 'Lookup Display Attributes' field, so that multiple fields are shown in the LOV.
When you use UIX and have an Entity Association to the Entity Object in the LOV, passing back multiple fields is already possible. But in your case, you will probably have to use your own javascript to implement this functionality.
Kind regards,

CreateInsert and LOV with multiple return values

HI. I am on Build JDEVADF_11.1.2.3.0_GENERIC_120914.0223.6276.1
I have a View Object which is based on Entity Object.
View Object has customer_name and customer_id attributes.
customer_name attribute has LOV (input field with LOV) based on some other View Object (which of caurse holds customer name and customer id data)
I defined that when LOV return the chosen values it will populate customer_name with "Customer Name" value and customer_id with "Customer Id" value
All atributes are updatable
I droped my View Object on the page and also "CreateInsert" buton. When I click on "CreateInsert" button, I can see new row added as expected, customer_name field has LOV. I can choose from LOV and can see customers and customer_id data. But when I click OK in the LOV pop-up only customer_name attribute is populated!
I do see that customer_id is returned from LOV (I implemented ReturnPopupEvent listener), but still the customer id remains empty.
I though maybe I need to add LOV as auto submit = true and set LOV to be a partial trigger for customer_id. But still - it didn't help
However, if I run Application Module tester, I do get what I want. I can create new row and when I change customer name , both customer name and customer id fields are populated
Please advice

Hi Michael,
On Lov VO, make sure you have at least one or combination of attributes as Key attribute. and re test.
Thanks,
Jeet

Multi-select LOV return into single row

I have a multi-select lov setup on a column in a table layout. I want to be able to select the lov, select multiple rows in the lov and then when I press the select button in the lov window to have those lov records select return to the same column. Currently, the lov returns the multi lov records into multiple records on my table layout.

IN JHeadstart 10.1.3, we will add the option to return multiple selected values as a comma-separated list into the same field. With 10.1.2 this is not possible. You can implement this yourself by overriding method JhsDataAction.onLovSelect.

Select list with multiple columns

I want to create a select list with multiple column option. What are the options. Any developments in apex 3.0.1 ? Thanks in advance. I tried the tutorials by Kubicek.
I am kind of stuck to see the function entry inside LOV definition returns a error.

Still really one column.
If they need to be independent then you've got to have three selection lists.

How to create multiple rows in a child table from the multi select Lov

Hi
We have Departments and EmployDept and Persons tables and each employee can associate multiple departments and vice versa.While creating a Department page there should be a Multi Select LOV(values from Persons table) with search option for the Persons.From the search panel we can select multiple persons for that department.Suppose we have selected 5 persons and click on submit, then it should create 5 rows in the EmployDept table for 5 persons with that department id.
Any inputs on how to implement this scenario please..

Maybe you can get some ideas from here -

Creating Select List with multiple columns

I want to create a select list with multiple columns. I followed the demo application model described in the by Denes Kubicek (Currently my reference for APEX !!)
The code is as follows:
CREATE OR REPLACE FUNCTION getcrops(p_cropid IN NUMBER)
RETURN VARCHAR2
IS
v_cropid VARCHAR2 (400);
v_fcode VARCHAR2 (400);
v_product VARCHAR2 (400);
v_var VARCHAR2 (400);
v_fname VARCHAR2 (400);
v_acres VARCHAR2 (400);
v_style_start VARCHAR2 (400);
v_style_end VARCHAR2 (400);
v_return VARCHAR2 (400);
BEGIN
FOR c IN (select "CROP"."CROPID" as "CROP ID",
     "CROP"."FIELDCODE" as "FIELD CODE",
     "CARROTPRODUCTLIST"."CARROTPRODUCTNAME" as "PRODUCT",
     "VARIETYLIST"."VARIETYNAME" as "VARIETY",
     "FIELD"."FIELDNAME" as "FIELD NAME",
     "CROP"."SIZEINACRES" as "ACRES"
from     "FIELD" "FIELD",
     "CARROTPRODUCTLIST" "CARROTPRODUCTLIST",
     "VARIETYLIST" "VARIETYLIST",
     "CROP" "CROP"
where "CROP"."CARROTPRODUCTTYPE"="CARROTPRODUCTLIST"."CARROTPRODUCTID"
and     "CROP"."VARIETYID"="VARIETYLIST"."VARIETYLISTID"
and     "CROP"."FIELDID"="FIELD"."FIELDID")
LOOP
v_cropid := TO_CHAR (c.'CROP ID', 'FML999G999G999G999G990');
v_fcode := c.'FIELD CODE';
v_product := c.'PRODUCT';
v_var := c.'VARIETY';
v_fname :=c.'FIELD NAME';
v_acres :=c.'ACRES';
FOR i IN 1 .. 12 - LENGTH (c."CROP ID")
LOOP
v_cropid := v_cropid || ' ';
END LOOP;
FOR i IN 1 .. 12 - LENGTH (c.'FIELD CODE')
LOOP
v_fcode := v_fcode || ' ';
END LOOP;
FOR i IN 1 .. 12 - LENGTH (c.'PRODUCT')
LOOP
v_product := v_product || ' ';
END LOOP;
FOR i IN 1 .. 12 - LENGTH (c.'VARIETY')
LOOP
v_var := v_var || ' ';
END LOOP;
FOR i IN 1 .. 12 - LENGTH (c.'FIELD NAME')
LOOP
v_fname := v_fname || ' ';
END LOOP;
FOR i IN 1 .. 12 - LENGTH (c.'ACRES')
LOOP
v_acres := v_acres || ' ';
END LOOP;
v_return := v_cropid || v_fcode || v_product || v_var || v_fname || v_acres;
END LOOP;
RETURN v_return;
END;
I created this anonymous Pl/SQL function at a application level ..Then I followed up to create a select list with a function inside. However I could not create select list with the command suggested in the demo which is
select getcrops(cropid) d, cropid r from crop;
APEX (2.1) returns a error message. What am I missing ? Should the function be called from somewhere else after creating a regular select list..? Where the functions (Pl/SQL) should be ideally stored for application level access..? and for across application level access ? How can I check the function works good. Help is appreciated.

Still really one column.

Problem with Headstart Multi-Select LOV

Hi,
I'm working on a few forms which should include a Multi-Select
LOV. Now here's the problem: One MSEL doesn't close; you can
select record(s), the LOV returns them, but doesn't disappear.
Clicking Cancel doesn't help.
Another MSEL-problem in another form: if you click Select All,
this selection isn't visible in the MSEL. He returns all of the
records, but it looks like he only selected one. Working with
CTRL to select more than one record doesn't work either. This
one closes fine.
As you know I have to include module component
QMS_MSEL_LOV_BUTTONS (which includes all button-functionality),
and then it should work, but it doesn't.
We've checked all the properties and they seem to be correct. It
isn't the first time we encountered these problems. We always
rebuilt the MSEL LOV, but it doesn't help this time.
Has anyone got an idea what's causing this problem.
P.S. There are also MSEL LOV's which operate just fine, without
any problems; only these two are doing strange things.
Thx,
Wouter

Workaround provided by Lauri Boyd seems to have worked:
A bug (#1985903) was introduced in Forms 6.0.8.13.0 and later which affected Headstart. This was fixed in Headstart patch 6.5.2.1 which is available through the Supplement Option.
Description
===========
1. When using a multi-select LOV (which is displayed in a modal dialog
window), you select the records you want, press OK, and the application exits.
2. When using a shuttle control to move records from left to right or vice
versa, you select the records you want, press '>' to move them, and the
application exits.
This occurs in Forms 6.0.8.13.0 and 6.0.8.14.1. It did NOT occur in prior
releases. This is some kind of forms bug.
Workaround
==========
For some reason the call to procedure renumber in qms$msel.process_records
causes the application to exit. If you copy the code from renumber to all the
places from which it is called, it works fine.
- open qmslib65.pll in Form Builder
- open package body qms$msel
- find procedure process_records and define a local variable l_recno of type
number.
- find local procedure renumber and copy the body of this procedure
(everything
after 'begin' and before 'exception').
- replace each call to 'renumber;' with the copied code.

Multi-select LOV does not work in forms

the multi select LOV does not work in the form.
the LOV works individually but in the form it does not work. it does not allow multiple selection from the list.
is there a workaround for this or is this a bug ...?
any ideas ...?
thanx a lot.
null

Right, we cannot store more than one value in a single column in a table :), we were getting a lot of requests to support multiple select LOVs but requirements were contradictory if not mutually exclusive.
The only sense it makes is when used together with user-defined object types (nested tables for example) but the current [application building]infrastructure we have does not support this. However, we are looking into this and this feature maybe implemented in a future release.

Multi Select LOV Gives CDI-21600

Have discovered that the Multi Select LOV facility is causing error CDI-21600 in some circumstances.
We have 2 tables -
Instance_Type_Owners
ito_int_id
ito_owner_org_id
ito_owner_ort_id
ito_created_by
ito_created_date
pk is the first 3 columns
Instance_Type_Relations
itr_ito_int_id1
itr_ito_owner_org_id1
itr_ito_owner_ort_id1
itr_ito_int_id2
itr_ito_owner_org_id2
itr_ito_owner_ort_id2
pk is all 6 columns, with 2 fk's pointing back to Instance_Type_Owners.
I'm creating a 2 block form, master block has base table of Instance_Type_Owners, detail block has base table of Instance_Type_Relations, using a key link based on the fk pointing back to id1's. I also want a multi-select LOV using the fk pointing back to id2's. This is giving me CDI-21600; the error goes away if I take the Template/Library Object qmsso$msel_lov_item off the leading element of the fk used by the LOV (i.e. itr_ito_int_id2).
I've double-checked everything about the definitions of these tables/pks/fks, & everything looks ok. I've successfully used multi-select LOV on other tables with a similar fk structure (ie relationship tables, with 2 fks pointing back to the same master table), & with multi-column fks, so it's not being caused by any of these reasons.
Any ideas on what may be causing this?

Thanks for the response. I have seen the checklists for causes of this problem, & have checked all tables/fks/pks involved in the form. I can successfully generate forms which maintain these tables, or with lookups to these tables. The problem only happens when I use the Headstart multi-select LOV facility. As I said, the problem goes away immediately I remove the 'qmsso$msel_lov_item' template/library object from the leading element of the fk in the base table.
If I go to Designer support & tell them this, I'm pretty sure they'll say it's a Headstart problem, since it only happens when Headstart facilities are involved.

Dynamic select list with display,return val & join condition issue.

hello,
I am having a dynamic select list with display, return value
say for example my select statement is
select distinct dname d, deptno r
from dept dt
right join emp e on (e.deptno=dt.deptno)
where (condition)
when i tried this query for my select list, it is not working. It saying that
" LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query. "
I am not able to understand the problem. Can anyone help me out with this issue?
thanks.

Shouldn't your join have dept as the driving table?
select distinct dname d, deptno r
from dept dt
right join emp e on (dt.deptno = e.deptno)
where (condition)
Or using older Oracle standard join
select distinct dname d, deptno r
from dept dt, emp e
where (dt.deptno (+) = e.deptno) AND (OTHER WHERE condition)
OR
(Since a right join is just getting the values from the driving table that are NOT in the associated table)
select distinct dname d, deptno r
from dept dt
WHERE dt deptno NOT IN (SELECT deptno FROM emp) AND (OTHER where condition)
Thank you,

Multi-select LOV bug and Developer6i R2 Patch7

Has anyone verified that Patch7 corrects the problem with multi-
select LOV bug (see below). The Headstart6i Report Launch form
(QMS0012F) exhibits this bug (when using the demo reports for
example) and we were unsuccessful applying the workaround (see
below). We will upgrade to Patch7 if this bug is fixed or we
could use a little help from the HeadStart team correcting the
Report Launch form to get around this bug. Thanks, Keith
We have found one odd quirk with Headstart 6i and Forms
6i versions 6.0.13 and higher.
Description ===========
1. When using a multi-select LOV (which is displayed in a modal
dialog window), you select the records you want, press OK, and
the application exits.
2. When using a shuttle control to move records from left to
right or vice versa, you select the records you want, press '>'
to move them, and the application exits. This occurs in Forms
6.0.8.13.0 and higher. It did NOT occur in prior releases. This
is some kind of forms bug.
Workaround ==========
For some reason the call to procedure 'renumber' in
qms$msel.process_records in qmslib65.pll causes the application
to exit. If you copy the code from renumber to all the places
from which it is called, it works fine.

So far as I know, this bug has not yet been corrected.
You will have to apply the fix as described in your email
message.

Multi-select LOV's hang form and use 100% CPU power

Hello,
We are using Designer 6i (6.5.52.1.0) and Headstart 6.5
In one of our forms we are using 6 Multi-select LOV's.
When we click the Cancel or Ok button (included through QMS_MSEL_LOV_BUTTONS), or hit Enter query in one of the ML_... blocks the form hangs and starts using all the CPU-power. I've tested this locally (c/s) and through the web (iAS), same result...
I already rebuilt the LOV's but the problem isn't solved.
We've got other forms with one or two multi-select LOV's, and these work fine.
Has anyone experienced this behaviour before, and what is the cure?
Thanks in advance!

Wouter,
If you are running against Solaris, you could be running into the following:
Headstart applications that run via webforms on a Sun Solaris application server, suffer again from bug 1985903. This bug was spotted and solved a time ago and seemed to be solved at next
releases of Forms 6i. Now, on Solaris the bug is introduced again.

Is it possible to Add to Multi-Select Lov through Customization?

Hi All,
I have a Oracle Seeded page( Oracle Training Administrator).
Clients wants a new field with Multi-Select LOV on that.
Is is possible to create Multi-Select LOV through Customization or changing the page in JDeveloper?
As per OAF Developer guide, Multi-Select Lov on single field in not possible and their is topic on 'Multi-Select on Advance Table'.
Please guide me, is it possible? If Yes, steps to achieve this will be great help for me.

That is correct you can only add a normal LOv through personalization and not a multi select LOV.

Processing Multi Select LOV Results in Portal Forms

Hi,
I want to be able to create a portal form where i can use a multi-select LOV to create multiple records on a seperate table. How does one 'capture' all selected items so that one can do a seperate insert into a child table containing the items? When querying the form how can one programmatically set the items so that they appear as selected.
Thanks

Hi,
Were you able to fix this up? If so, can you please provide me some directions?
