Bug in select LOV ?

Hi All,
I have report error:
"ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small" when I try to build select LOV on a column in wisard-generated tabular form. This happens when the LOV is quite long. The lookup table has about 850 values. But if I restrict query result set with rownum < 600, the form works fine.
The example is available on http://htmldb.oracle.com/pls/otn/f?p=24345:1
How to workaround such a problem?
Thanks

Follow Up:
After some discussions with Steven I tried to move some stuff around. Eventually I found out that if the ViewObjects on which these two table-blocks are based are built on different Entity Objects, then the application works as desired.
So the conclusion seems to be: it is not a good idea to have - probably in the same UIModel - multiple Iterators based on ViewObjects that are based on the same EntityObject.
Note: this is only a work-around: I still do not know exactly what goes wrong and why! It can be in JHeadstart runtime (not so likely), in ADB Binding Layer (very likely) and potentially in ADF BC (quite unlikely).
best regards,
Lucas

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

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.
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.
A new version of qms$msel package body is available on iXchange for download.

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

application exits.
This occurs in Forms 6.0.8.13.0 and 6.0.8.14.1. It did NOT occur in prior

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.

All values from multiple select LOV

Hi.
Ik have a customize screen for a chart where a can select days. That works. But i want the standard value to be 'all days', so the user does not have to click all seven days. When i have combobox i use in the where clause:
"and (fieldname = :variable or :variable = '%')"
For a mutiple select i use IN:
"and fieldname IN :variable"
That would make:
"and (fieldname IN :variable or :variable = '%')"
This does not work for a multiple select LOV.
Anu ID how i can make it work???

Try the following:
(:variable = '%' or
:variable <> '%' and fieldname in :variable)

How to select LOV items from edit report / form?

I'm new to ApEx 3 with very little web developer knowledge.
I have a create record form (Page1) that uses single-select and multi-select LOVs and correctly inserts the data into a table.
I have a basic report (tabular form) (Page2) that shows the records with the correct LOV information. When I click the edit icon for a row on Page2, Page1 displays row data for each field except the LOVs. There are no selections made in any of the LOVs.
How do I make the connection between the tabular report and the edit form LOVs?
Thx for your assistance.

It turns out that the imported data did not match the LOV values. We changed the ETL processing, and now the LOV values are selected as expected.

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 -

Select LOV in a report

hi,
I'm having a problem with the select LOV (query base) in my report. I'm using Application builder to construct my report. My query is this:
Select proj_desc name, proj_code code FROM TM_Proj
where (substr(:p1_customer,1,1) = '*' or :p1_customer is null)
union
Select proj_desc name, proj_code code FROM TM_Proj
where substr(:p1_customer,1,1) != '*' and :p1_customer is not null and cust_gen_nbr = :P1_customer
I consistantly get this error: ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
I don't get this problem if I change it to "display as text based on LOV". However, when I changed it to "Popup LOV based on query," I get Popup List of Values authentication failed.
Can anyone provide any insight on this?

this is from ApEx forum, it may help;
Generated HTML for report rows cannot exceed 32K. Select lists must be >> reasonable in size. It appears that you have too many entries in them to use them >> thrice per row. You should consider popup LOVs instead.

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.

Selected Lov Value as Parameter to Concurrent Program in oaf

Hi,
iam new to OAF ,Can any one please help me how to pass selected lov value as a parameter to the Concurrent program in oaf.
i created one lov in oaf page after selecting value in lov i want that value to be passed as parameter to concurrent program.
Please help me how to implemet code so that Lov will pass as parameter to the concurent program in Controller.

Check these links. You need to get the value from the LOV to a variable, add it to the vector and pass to the conc program. Below link provides the details on concurrent program submission.

For fetching LOV values, check the Dev Guide

Multi-Select LOV for Report Parameters

I have a LOV defined in Oracle Portal as a Multi-Select LOV. When I assign this to an optional report parameter when defining a reports definiton file and run the parameter screen, it comes up as a combo box. Is a combo box the only type of LOV I can use for an Oracle Reports Parameter.
Thanks
Jody

With whatever i could make out is you are trying to change a discovere report to xml; publisher report isnt it?
To answe to your question, directly it is not possible to have In clause but you could use some smart logic like lexical parameters etc to achieve similar things.I guess you cannot do in in EBS Reports too.

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.
