Dynamic popup LOV

I have a select list with 3 values. The value chosen determines the table name and column name to be used for a subsequent popup LOV.
How can I do this?
The query for a popup LOV doesnt seem to accept a PL/SQL block returning a query like a report region does.
Thanks

OK I got this.
I changed the select list to 'select list with redirect' so that it sets just that value in session state and wrote my LOV query as
select col1 d,col2 r
from table1
where :P1_SELECT='Table1'
union all
select col3 d,col4 r
from table2
where :P1_SELECT='Table2'
union all
select col5 d,col6 r
from table3
where :P1_SELECT='Table3'
Depending on the value of the selected item, only one of the above queries should be executed.
Thanks

POPup LOV Dynamic List of values

Hi All,
I need to change the list of values of a popup Lov in my application depending on a checkbox.
Like:
If I the checkbox is checked by the user the list will come from Table A and if the checkbox is unchecked the the list needs to come from Table B.
I need to bind this to the checkbox click event. But I don't know which option should I use to create this Dynamic action.
Please help me out as Its urgent..... I got the deadline today..... :(
Thanks in advance.....

Solved with cascading feature.. Thanks All.

Switch item display type dynamically? popup-lov | select-list

Hi,
I've got a select-list item which I want to switch dynamically to a popup-lov. I want to display a popup-lov when the number of items to select from is high (say more than 15), otherwise I want to display a selct-list. How can I achieve this?
thanks,
Stephan

The simple approach is to create separate Select List and Pop-up LOV items and use conditions based on the number of available options to display the correct one. The items have to have different names, so if this is to be used for example to provide a value for a database column, create another hidden item based on the database column and transfer the values between the UI and DB items using computations.

Dynamically load Popup LOV

I need to load a Popup LOV with values filtered by a previous selection in a standard Select List. I need to do it without submitting the page to place the filtering LOV's value into session state (I've got other things happening on submit). 
I've used Carl's cool AJAX solution for standard Select Lists. Is there a similar method that will work when the target LOV is a Popup?
thanks, 
Mark

A select list (dropdown) is part of the page when it is rendered, that is why the AJAX stuff is needed to replace the dependent dropdown lists.
With popup LOVs, it is much simpler because the popup LOV query is not run until you click on the popup icon.
If the popup LOV query refers to session state (:P1_ITEM), all you need to do is set the session state using the AJAX snippet.
Put onchange="foo(this);" into the HTML Form Element attributes of the first select list (say P1_ITEM) and use something like
function foo(pSelect)
var l_select=html_SelectValue(pSelect);
var get=new htmldb_Get(null,html_GetElement('pFlowId').value,'APPLICATION_PROCESS=null',0);
get.add('P1_ITEM',l_select);
get.get();
get=null;
}"null" is a on-demand Application Process that does nothing. A PL/SQL block with just "null;"
That's it. Now when you click on the popup LOV, it will get the latest value of P1_ITEM in session state in its defining query.
Hope this helps.

Disable/enable popup LOV image anchor in tabular form

Hello all,
I am trying to find the solution how to enable/disable popup LOV's image anchor. When I disable the popup item, then only the text field is disabled but the image is still active and opens the LOV window. I have tried to implement some solutions but without success.
I have created DA (fired after refresh of needed region) with code below which disables the needed field.
$('td[headers="DEPTNO"] input').each(function(i)
            $('td[headers="DEPTNO"] input:text').disabled="disabled";
$($('td[headers="DEPTNO"] input:text')[i]).addClass('apex_disabled');
Could anyone help me with a code which will also disable the image?
Thanks in advance!

Hello Jiri,
Please see your page:
I have changed the dynamic action:
$('td[headers="DEPTNO"] input').each(function(i)
            $('td[headers="DEPTNO"] input:text').disabled="disabled";
$($('td[headers="DEPTNO"] input:text')[i]).addClass('apex_disabled');
     $($('td[headers="DEPTNO"] a')[i]).click(function(e) { e.preventDefault(); });
$($('td[headers="DEPTNO"] img')[i]).addClass('apex_disabled');
Hope it helps!

How to get the value from one Popup lov column to another popup lov column

Hi,
I am new to oracle apex development and having the below issue.
In my application, there is a tabular form with 15 columns ( c1.. c15).
I have to populate the value of column C5 based on the selected(from popup lov) value of column C3, tried to use onchange, but didn't help much.
Any help please.
Thanks and Regards,

Oh boy, this is a fun one.
onchange should work theoretically (in this example, assume that f05 is the target column that should be set and "this" is the source item whose value is to be transferred to f05 on the same row (row 2)):
onchange=$s('f05_0002',$v(this));
BUT the catch is of course that needs to be different for every row (can't hardcode the '2'), so you need something to dynamically create the row number component.
I wrote this for an app I'm working on that uses master-detail forms heavily (I also wrote a lot more code to read the fmap array that is in v4 so that I can reference my cells via their column name and not the numeric position (so "f05 can be determined w/o hard coding), insulating against columns moving around, columns being made display-only etc. but I won't bore you with that here unless you really need to know).
function getRow(pObj)
{ //Pass in an object reference to a tabular form cell and get back an integer
//derived from the object ID.
var vRow=pObj.id.substr(pObj.id.indexOf("_")+1);
if (isNaN(vRow))
 return (null);
return (parseInt(vRow,10));
function formatRow(pRow)
{ //Pass in an integer and it'll be returned as the tabular form cell ID suffix
//(e.g.: pass in 1 and get back string "_0001").
//Used in building ID references to tabular form cells.
if((isThingEmpty(pRow)) || (isNaN(pRow)))
 return(null);
var vRow=pRow.toString();
while(vRow.length<4)
 vRow="0"+vRow;
return("_"+vRow);
}Therefore:
onchange=$s('f05_'+formatRow(getRow(this)),$v(this));
So in essence, pass in "this" which will be a reference to the current item, largely to determine what row we're on. getRow will return 1, 2, 3, etc. formatRow will take that and return 0001, 0002, 0003, etc. Once that is done, it'll concatenate with the f05 and f04 to refer to the correct columns (determining f05, f04, etc. dynamically is another matter if you really need to but I didn't want to complicate this answer too much at once).
Note: above I also use a isThingEmpty() function that I wrote. It does nothing other than check the item for an empty string, if the item is null, etc. Just do your own evaluation of empty-string, no-value, etc. there.
It would indeed be nice though if Apex had a better way to delclaratively access the tabular form items though. Despite all the v4 enhancements, tabular forms were not entirely upgraded to the same full functionality of page items.

Return multiple values for the popup LOV

Hi folks,
I have one challange. I have a search engine and there is an popup lov and its having three Display and 3 Retun value such as
select
p.A || ', ' || pi.B|| ', ' || km.C|| ' ' d, p.A || ', ' || pi.B|| ', ' || km.C|| ' ' r
from tableA km,tableB p,tableC pi
where km.col1=p.id and km.col1=pi.id and km.C is not null
when i click on the pop lov it will display 3 values shuch as SAP+DBA+HR and in popup lov iteam its will return 3 values
such as SAP+DBA+HR this return values are from 3 cloumn names from same table ie. A column, B column, C column
and when i click on submit button this return values from 3 columns values should assign to the 3 column such as
A=SAP, B=DBA and C=HR and search fetchs the result in a Report.
Its some thing new, is it possible..:)
ok will be waiting for your reply..:D

Suri

Hi Varad,
am facing problems i wrote dynamic sql its working fine for 2 and 3 fields like (SAP+ORCL) and (SAP+ORCL+HRA) but for the single value like SAP the results are not comming properly. my code is
If (:P25_TEST Is not Null ) THEN
V_Sql := V_Sql||q'!
And
(multipleInstr1(R.Pillar,:P25_TEST)>0 )
or INSTR ( '+' || Upper(:P25_TEST) || '+', Upper(R.Pillar))>0 ) and
((multipleInstr1(R.Product_Line,:P25_TEST)>0 )
or INSTR ( '+' || Upper(:P25_TEST) || '+', Upper(R.Product_Line))>0) and
((multipleInstr1(R.Category,:P25_TEST)>0 ) or (R.Category is null)
or INSTR ( '+' || Upper(:P25_TEST) || '+', Upper(R.Category))>0 )
End If;
where multipleInstr1 is a function created to search results even its delimited by '+' it ignors '+' delimiter and
:p25_test is the popup iteam which takes values like SAP+ORCL+HRA or SAP+ORCL or SAP how its possible to get this results.
Its turning too complicated for cheking condetion for a single popup iteam, can we get any solution for this or not..
Hope will do respond
Thanks and Regards,

APEX 4.0 - AJAX not working with Popup LOV field

Hello,
In the application I have built I have three fields which are 'feeded' by selects via a AJAX construction.
All three fields are based on three others, which are PopUp LOV fields. Up to version 3.2 I had no problems: the fields were 'refreshed' as expected when in the 'parent' field a specific value was entered or choosen by the Popup Lov selector.
But since the migration to APEX-4 (lin a test-system) all the three fields are not correctly refreshed anymore: two of them give the value 'undefined', the third, which is a select-list shows values, but at the moment I try to click on the select-list down arrow to pick a value, the list is emptied and stays that way.
More specific about the third field:
item 1 is a popup-lov defined item in which a user can type a value, but can also choose a value from a popup-lov. Item 2 is based on item-1: it does a select based on the value of item-1 and refreshes a select-list. Item-2 is defined as a select list.
I got it all working when making item-1 also a select list, but since the list can become very large, I made a Popup lov of it. Most users do know what code they have to enter and in case somebody is not sure, the lov can be used.
In this forum I came across a problem with AJAX callback, which was answered by Patrick Wolf, saying that in an htmldb_Get ( ... ,0) the last 0 should be replaced by $v('pFlowStepId'), but this did not fix my problem. I have the feeling that the problem is somewhre else, since on first hand, after entering a value in item-1 I see item-2 refreshed with the correct values, but the moment I try to select one item, the list is emptied.....
I hope I made it clear what my problem is and that somebody can help me, else APEX-3.2 was the latest version for this application....
Thanks in advance and best regards,
Jan.

Hi Jan,
the problem is the
onBlur="javascript:f_P21_select_kostenposten(this,'P21_KOSTENPOST');"on P21_GBREKNR. This is getting attached to the HTML input text field but as well the the anchor link which opens the popup. So when you leave the text field the cursor will be put onto the icon to open the Popup LOV. When you press tab another time or leave the anchor link by clicking somewhere the above JavaScript function is fired again. But the problem is that "this" this time points to the anchor and not the text item anymore, so it will return an invalid value when you access this.value in your f_P21_select_kostenposten function which results in an empty result of your on-demand call.
I still have to investigate why the above JavaScript code is now added to the anchor link as well. But as a workaround, just change your code to
onChange="javascript:f_P21_select_kostenposten(this,'P21_KOSTENPOST');"which is better anyway, because it's just firing when the value really got changed. And because the anchor link can't really be changed, the event will never fire when you leave the anchor. BTW you can use the Application Search feature to search for all your onBlur events. onChange is much better than onBlur because it doesn't fire that often unintended.
But if you want to use some of the new APEX 4.0 features, you could use the cascading LOV feature of APEX 4 and avoid all this JavaScript and on-demand code which you have written.
I have changed your application to take use of it.
1) I changed the LOV query for P21_KOSTENPOST from
select '('||replace(lpad(gbreknr, 3, chr(1)),chr(1),' ')||') '|| omschrijving d, kostenpost r
from kostenposten
where vervallen is null
and bedrijf = :P21_BEDRIJF
order by gbreknr, kostenpostto
select '('||replace(lpad(gbreknr, 3, chr(1)),chr(1),' ')||') '|| omschrijving d, kostenpost r
from kostenposten
where vervallen is null
and bedrijf = :P21_BEDRIJF
and (:P21_GBREKNR is null or gbreknr = :P21_GBREKNR)
order by gbreknr, kostenpostas it was in your on-demand process. The query will return all values if P21_GBREKNR is null but will restrict it if the field is filled out.
2) Set "Cascading LOV Parent Item(s)" to P21_BEDRIJF,P21_GBREKNR Because based on your LOV query I assume "Kostenpost" should be refreshed if one of the two fields gets changed.
3) Set "Optimize Refresh" to No because one of your parent items (P21_GBREKNR) can contain a null value.
4) Removed the onBlur/onChange from P21_GBREKNR
5) Removed the *%null%* from the "Null Return Value" attribute of P21_BEDRIJF, because that will cause a ORA-1722 if someone picks "-- kies: --"
That's it.
Have a look at dynamic actions and the "Set Value" action as well, because I think that could remove your other on-demand calls as well without having to write any JavaScript code.
I will still investigate what's going on with the anchor link in APEX 4.0

Patrick

Is there a problem using popup LOVs in a portal form with a bind variable?

I have a portal form with 2 LOVs. The second LOV is a dependent LOV whose bind variable can be NULL. I have read Note 263923.1, "How To Create Dependent Lovs In Forms", and my form works as long as I use combo boxes to display the LOVs. I need to use popups so the user can search the LOVs as they are quite lengthy. Plus I want to be able to pick a value from my second LOV without selecting a value from the first LOV -- hence, my bind variable can be null and that is where my problem lies. As long as I select a value from the first LOV, the second LOV popup will work. If I click on the icon to display the second LOV without pre-selected a value from the first LOV, I get the following error:
POPUP LOV ERROR:
LOV: "9A17692880B6B8509F514F5B9CA9EC808DD403218B3CF19A33C04CD1FAB0ADE17ADC33E6B67998A933357CE5264D204E"
Parse Message: Parse as pre-set global: "TORE".
Find Message: LOV is of type DYNAMIC (LOV based on SQL query).
Query: "SELECT ...."
wwv_bind.prepare_bind: ORA-01403: no data found
My form is based on a table with a custom layout. The sql for the second LOV is similar to: SELECT ENAME, EMPNO FROM SCOTT.EMP WHERE (DEPTNO = :DEPT AND :DEPT IS NOT NULL) OR :DEPT IS NULL.
Thanks in advance for any help,
Carol

Don't use EPS any more! It does not support transparency nor color management.
If you save vector files from Illustrator, use AI with PDF compatiblity.
If you save image files from Photoshop, use PSD.
If you save image files combined with vector forms and/or text from Photoshop, use PDP which is a Photoshop PDF.
For vectors from Illustrator use CMYK files.
For images use RGB, conversion to CMYK should never done before PDF export, better, if the printer allows it, is to export a PDF with live transparency as it is PDF/X-4
If the printer requires a PDF with CMYK only export a PDF/X-1a.

Apex 2.2 popup lov doesn't return chosen value

Hey,
I've built a page within one of my applications in apex 2.2 that has an item based on a Popup LOV. I have a pre-built dynamic LOV.
When I run the page the popup icon appears and I can launch the popup. The filters work, and the result set appears. However, if I attempt to click on a value, nothing happens. The window remains opened and no value is returned to the parent window. The browser window shows no sign of javascript errors.
I'm using Theme 11 and the standard popup template.
I've tried this is a different workspace, using the same lov sql etc, and it works ok!
I've tried it elsewhere in a new page within my problematic application, and the problem is replicated there too.
What could be going wrong?
Cheers,
John

Base a popup lov on another popup lov

I created 2 dynamic lovs.
The first one, Lov_project, has the following code:
select project_id, project_name
from ke_projects
The second Lov_budget:
select budget_version_id, budget_vesion_name
from ke_budgets
where project_id = :project
Project_id is a field of ke_budgets and ke_projects
I created a procedure based on a stored procedure:
rocedure KE_TEST(p_project in varchar2,
p_budget in varchar2) is .....
Then I use the field p_project for lov_project and p_budget for lov_budget
Next to the bind variable, I choose lov_project.
I can choose a project but when I click on lov_budget I have the following error:
POPUP LOV ERROR:
LOV: "APP_MATTHIEU.LOV_BUDG"
Parse Message: Parse as pre-set global: "KEV".
Find Message: LOV is of type DYNAMIC (LOV based on SQL query).
Query: "select VERSION_NAME, BUDGET_VERSION_ID from KEV.KE_BUDGET_VERSIONS where project_id = :p_project"
What is the problem?
Thanks

There can be one way of doing this,change your combobox (Driving LOV) to text box and assign a format mask to it.
After applying the format mask to it again change the text box to combobox.
one more thing you have to put fm before applying the format for eg.fm99999999999999999 or fm99999999999999.99
By doing these it should work.

Popup LOV (fetches first rowset)

Hi experts,
I would like to set the return value of Popup LOV(fetches first rowset) which calls P10_ORG_NAME to P10_ORG_ID when I select the value of LOV dynamically.
In the current setting above, P10_ORG_ID is getting the return value when submitting a button :-(
Does anyone have any idea?
Thanks,
Rui

OK I got this. The popup LOV window contains only those records that match what I have entered so far before clicking on the popup icon.
Sorry for the noise, thanks.

Theme 23 does not display popup LOV in tabular form

I created new application using new Theme 23. In tabular form the popup LOV button does not show. While using this theme the column LOV button is soooooo small it is not visible. If I move the cursor on the side of the field eventually I cursor handle will change and I can click and popup LOV will show. When I switch to an older theme (e.g. 21) the LOV button shows just fine.
Does anyone can offer a solution? Can I expect more this type of problems in the new theme 23?

I examined exported application file. Indeed the problem is p_column_id parameter. It should be decimal number for translated application. Characters %2C in p_column_id value stands for comma. It should be dot instead. Parameter value should be p_column_id=30289208519476123679.915121.

Popup lov in a report is not working if I have an order by caluse

I created a form manually using the document from the url:
http://otn.oracle.com/products/database/htmldb/howtos/tabular_form.html#MANUAL
I used the following query from that document.
select htmldb_item.hidden(1,empno) empno,
ename,
htmldb_item.select_list_from_query(3,job,'select distinct job, job from emp') job,
htmldb_item.popupkey_from_query(4,mgr,'select ename, empno from emp',10) mgr,
wwv_flow_item.date_popup(6,null,hiredate) hiredate,
htmldb_item.text(7,sal,10) sal,
htmldb_item.text(8,comm,10) comm,
htmldb_item.select_list_from_query(9,deptno,'select dname, deptno from dept') deptno
from emp
This works fine.
But if I add an order by clause to the query the popup key for mgr column doesn't work.
select htmldb_item.hidden(1,empno) empno,
ename,
htmldb_item.select_list_from_query(3,job,'select distinct job, job from emp') job,
htmldb_item.popupkey_from_query(4,mgr,'select ename, empno from emp',10) mgr,
wwv_flow_item.date_popup(6,null,hiredate) hiredate,
htmldb_item.text(7,sal,10) sal,
htmldb_item.text(8,comm,10) comm,
htmldb_item.select_list_from_query(9,deptno,'select dname, deptno from dept') deptno
from emp
order by ename
Is this a bug ?
Is there a work around ?
Thanks
Chandra.

Chandra,
Please refrain from asking the exact same question twice. It doesn't help the quality of this forum. If you have to, "bump" an existing unanswered question up (wait a day or two, please) in case it fell through the cracks.
Now for the answer:
select htmldb_item.hidden(1,empno) empno,
ename,
htmldb_item.select_list_from_query(3,job,'select distinct job, job from emp') job,
htmldb_item.popupkey_from_query(4,mgr,'select ename d, empno r from emp',10) mgr,
wwv_flow_item.date_popup(6,null,hiredate) hiredate,
htmldb_item.text(7,sal,10) sal,
htmldb_item.text(8,comm,10) comm,
htmldb_item.select_list_from_query(9,deptno,'select dname, deptno from dept') deptno
from (select * from emp order by ename)
Use an inline view like in the example above to do the sorting first. If you sort a result set that includes Popup LOVS, then the Javascript used to populate the text fields doesn't work anymore.

How to create a condition based on a select that retrieve dynamically a LOV

Hi all, I need to create a condition based on a select that retrieve dynamically a LOV.
So, the condition have to be:
inventory_item_id NOT IN (SELECT inventory_item_id FROM apps.mtl_system_items_kfv WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV')
I need to create a LOV based on this select without making any join with the folder which contains the field inventory_item_id, because otherwise I have the contradiction:
and o124757.INVENTORY_ITEM_ID = o118741.INVENTORY_ITEM_ID -- join between the main custom folder (o118741) and the LOV custom folder (o124757)
and o118741.INVENTORY_ITEM_ID NOT IN (o124757.INVENTORY_ITEM_ID) -- condition
These two condition together don't show any data, obviously....This means also, that I can't use a calculated field, because if I want to see this field, I have to create a join, another time, with the main custom folder.
I tried to create a LOV on the Administrator, but when I create the condition I have to check manually the values....and if in the future this LOV will increase I need every time to re-check all the values.....instead I need that the inventory_item_id have to be NOT IN dinamically in the list of values retrieved by the select.
Anybody has inplemented something similar ??
Thanks in advance
Alex

Hi alex,
SELECT incidents.INVENTORY_ITEM_ID,
pcodes.PROBLEM_NAME
FROM apps.cs_incidents_all_b incidents,apps.jtf_rs_problem_codes_v pcodes
WHERE incidents.category_id IN (SELECT category_id
FROM mtl_categories_kfv
WHERE concatenated_segments = 'IPTV')
AND incidents.PROBLEM_CODE = pcodes.PROBLEM_CODE
where incidents.INVENTORY_ITEM_ID NOT IN SELECT inventory_item_id
FROM apps.mtl_system_items_kfv
WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV'
You want to add this condition to the first query it holds good for this scenerio.All the items which are NOT IN will be retrieved.Here you are selecting other than "General_faults_iptv"
But again your trying to select in the second query where you want "General_faults_iptv"
SELECT inventory_item_id
FROM apps.mtl_system_items_kfv
WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV'
If you carefully go through what your doing,you will understand.In the above explantion ,there will be no records generated.First query your saying NOT IN and again your saying for the same IN,how will records retrieve its meaningless.
I dont know what you want to get from second query.I would suggest you to do is dont use the second query and just use the first query and you will get.Here is the query and this will give you result.
SELECT incidents.INVENTORY_ITEM_ID,
pcodes.PROBLEM_NAME
FROM apps.cs_incidents_all_b incidents,apps.jtf_rs_problem_codes_v pcodes
WHERE incidents.category_id IN (SELECT category_id
FROM mtl_categories_kfv
WHERE concatenated_segments = 'IPTV')
AND incidents.PROBLEM_CODE = pcodes.PROBLEM_CODE
AND incidents.INVENTORY_ITEM_ID NOT IN SELECT inventory_item_id
FROM apps.mtl_system_items_kfv
WHERE concatenated_segments = 'GENERAL_FAULTS_IPTV'
