Generic solution for cascading select lists/lovs

After implementing several times a select list/lov, which is depending on another item on the same page (see the AJAX example from Carl Backstrom), I thought that it was time to come up with a more generic solution where I don't have to implement javascript code and on-demand processes for each lov anymore.
I want to contribute my findings to the APEX community. More details about my solution can be found at
http://inside-apex.blogspot.com/2006/11/generic-solution-for-depending-select.html
Any feedback is welcome!

Hi Bjorn,
the "First schema provisioned" property is just available in "normal" workspaces, not in the "internal" workspace. But it's just the schema-name where the tables/... of your application are stored.
About your problem. Which version do you use? V2.0?
V2.0 doesn't have the APEX dictionary views, I think they have been created in V2.2.
So the only way to use my solution is to use the version which is stored into the FLOWS_... schema. But it has to be modified before.
1.) In the ApexLib.js file, all ocurrences of $x have to be replaced by html_GetElement => $x doesn't exist in V2.0
2.) Replace the FLOWS_020200 thru FLOWS_020000 in the header of the package (ApexLib_for_flows_020200.pks and .pkb)
3) Maybe you have to remove the where-clause restriction NVL(UPPER(ITEM_COMMENT), '@') NOT LIKE '%$APEXLIB_IGNORE_LOV$%', I'm not sure if the comment column exists in V2.0. Don't have a possibility to check that now.
I will come up with a solution on sunday or monday.

Cascading Select Lists - Not Working for me

I am trying to implement Denes Kubicek's Ajax Cascading Select List solution.
http://apex.oracle.com/pls/otn/f?p=31517:119
But it is not working for me.
I'm a newbie to APEX and checked the forum for advice on cascading select lists. I saw the thread for
"Cascading Select Lists - Not Working" posted by sue and the replies by Varad Acharya, but I'm still
having issues of not seeing the alerts, not able to run the pl/sql process in SQL Workshop, and not
getting the expected results.
I have a list of countries (US - USA, CA - CANADA, etc.) and a list of states for each country. When a
user selects a country I would like to show the list of states within that country.
This is what I've done so far:
Defined an application process:
Process Point: On Demand: Run ... by a page process.
Name: CASCADING_SELECT_LIST1
Process Text:
BEGIN
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn ('<select>');
HTP.prn ('<option value="' || 99 || '">' || '- All States -'
|| '</option>'
FOR c IN (SELECT state_code || ' - ' || state_desc d, state_code r
FROM tbk_state
WHERE country_code = :cascading_selectlist_item_1)
LOOP
HTP.prn ('<option value="' || c.r || '">' || c.d || '</option>');
END LOOP;
HTP.prn ('</select>');
END;

Now to the problem:
I run page 5 (the report) to see the list of locations and then I try to edit a record (page 6). When I
try to select a different country I get the following error (on IE):

Varad,
First, thank you for taking the time to try to help me with this problem.
When I view the page's source code (here are the first few lines):
<html lang="en-us">
<head>
<script src="/i/javascript/core.js" type="text/javascript"></script>
<link rel="stylesheet" href="/i/css/core.css" type="text/css" />
<script language="JavaScript" type="text/javascript">

<script>
function get_select_list_xml1(pThis,pSelect){
var l_Return = null;
var l_Select = html_GetElement(pSelect);
//alert ('Dept no=' + pThis.value);
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=CASCADING_SELECT_LIST1',0);
get.add('CASCADING_SELECTLIST_ITEM_1',pThis.value);
gReturn = get.get('XML');
// gReturn = get.get();
//alert('Enames=' + gReturn);
if(gReturn && l_Select){
var l_Count = gReturn.getElementsByTagName("option").length;
l_Select.length = 0;
for(var i=0;i<l_Count;i++){
var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'),
l_Opt_Xml.firstChild.nodeValue);
get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;

pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);
</script>
It looks like line 17 is:
var l_Select = html_GetElement(pSelect);
I'm still not sure why I'm getting this error and why it's not working?
Thanks,
Eti

Help with Cascading Select List in Tabular Form

Hello Friends,
I am trying to implement Denes Kubicek's sample for Cascading Select list and ran into this error:
Please help me identify what I might have missed ???
<code>
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

2.Created the hidden items
3.Created the buttons and items
4.Created the application process for MRU and Delete
5.Created the Application item [ TAB_CASCADING_ITEM]
6.Created the Application Process[tab_casc_sel_list]
Any clue/pointers to debug this are welcome.
I tried the above on apex.oracle.com; WS: CHAITANYAPATCHIPULUSU; USERNAME :[email protected]
PWD:Satya123 in APPLICATION : 12855 and Page :35
Regards..

OK, you didn't have the background process as an on demand process.
In the MRU and MRD process, you were referencing the wrong variables for the count. (as in deb's case, it's p176, but in your case its p35).
In the javascript function, the call that is supposed to assign : TAB_CASCADING_ITEM a value, isn't working (I believe).

How to populate another page item based on cascading select lists?

Oracle 10gXE
APEX 3.2
I've created cascading select lists based on the examples (using Javascript and AJAX) that i've seen on this forum. Thanks for help on that!
Now that I have these LOV's being populated without needing to submit the page, how do I take the value that is presently in each LOV and concatenate them together to populate another page item? I'm trying to build the URL string that will execute an Oracle Report once the user clicks a button.
Previously, when I had multiple Select Lists with a submit, the URL was being put together using an After Submit Computation that would set the value for an item (P26_REPORT_URL) on the page. Notice that a report parameter (i.e. parameter name and Select List value) is only included if the user has provided a value. The page item that holds these values is then referenced by a button for URL redirect. The URL Target for the button currently is: javascript:popupURL('&P26_REPORT_URL.'), but will not work at the moment because P26_REPORT_URL page item is not changing based on what is selected in the LOVs. Since I'm not submitting anything (do I need to?), how do I put together the values needed?
Computation for P26_REPORT_URL:
DECLARE
l_param VARCHAR2(2000);
BEGIN
l_param := '&REPORTS_URL.&report=&P26_RPT_VIEW..rdf&desformat=&P26_DESFORMAT.&destype=cache';
IF REPLACE(:P26_OLO_CODE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_olo_code=&P26_OLO_CODE.';
END IF;
IF REPLACE(:P26_BEG_DATE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_start_dt=&P26_BEG_DATE.';
END IF;
IF REPLACE(:P26_END_DATE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_end_dt=&P26_END_DATE.';
END IF;
IF REPLACE(:P26_ORG_CODE_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_org_code=&P26_ORG_CODE_2.';
END IF;
IF REPLACE(:P26_FLAIR_ORG_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_flair_org_code=&P26_FLAIR_ORG_2.';
END IF;
IF REPLACE(:P26_BUDGET_ENTITY_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_agy_code=&P26_BUDGET_ENTITY_2.';
END IF;
RETURN l_param;
END;

Andy,
This is a great suggestion! After I posted, I started looking at a Javascript solution and figured it's probably what I had to do.
However, now the cascading select list no longer working for some reason after I added the function to concatenate the item values. When I remove the showReport() function the select list works again.
Here is what I have in the HTML Header portion of the page:
<script language="JavaScript" type="text/javascript">
function popupURL (url) {
w = open(url,"winLov","resizable=1,width=800,height=600");
if (w.opener == null)
w.opener = self;
w.focus();
function showReport()
var l_param = '&REPORTS_URL.&report=' + $v('P26_RPT_VIEW') + '.rdf&desformat=' + $v('P26_DESFORMAT') + '&destype=cache';
if ($v('P26_OLO_CODE' != '')
   l_param += '&p_olo_code=' + $v('P26_OLO_CODE');
if ($v('P26_ORG_CODE_3' != '')
   l_param += '&p_org_code=' + $v('P26_ORG_CODE_3');
popupURL(l_param);
function get_AJAX_SELECT_XML(pThis,pSelect){
     var l_Return = null;
     var l_Select = $x(pSelect);
     var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ORG_SELECT_LIST',0);
     get.add('TEMPORARY_ITEM',pThis.value);
     gReturn = get.get('XML');
     if(gReturn && l_Select){
         var l_Count = gReturn.getElementsByTagName("option").length;
         l_Select.length = 0;
         for(var i=0;i<l_Count;i++){
             var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
if(document.all){
pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);

APEX Ajax Cascading Select List Tabular

Hi everyone,
We’re developping in APEX 4.X.
I went to your blog « Denes Kubicek - ApEx Solutions », it’s very interesting
http://apex.oracle.com/pls/otn/f?p=31517:176:384744492803038:::::
I tried to create something as Mr Kubicek did to get an Ajax Cascading Select List Tabular.
In step 5, he says the rest of the code if you apply for an account". Do we need to add a lot of code to get success ?
Is there someone who tries to do like Mr Kubicek did ?
Thanks in advance. Bye.
Eric.

Hi everyone,
I looked at Mr Kubicek solutions about tabular form and I asked him to get access to his workspace. But I’m not sure to get all I need.
I have a two select list named Activities and Entity. I want that Entity depends on Activities. Those list values come from respectively table h4_activities and h4_activity_entity.
But, when I show the tabular form, I want to see records which is in table h4_activity_day. I don’t want to see only my two select lists.
I think tabular form should be interesting.I want your advice.
But, I need something like a select list with a LOV and SOURCE.
Thanks in advance.
Have a great day. Bye
Eric

Apex 4.0 Cascading Select List: ajax problem with german umlaute

Hi everybody,
Apex 4.0
Dad PlsqlNLSLanguage: GERMAN_GERMANY.WE8MSWIN1252
I have problems with german umlaute and ajax cascading select lists (Cascading LOV Parent Item).
The data is populated without a page refresh in the select list when the parent select list changes but special signs like german umlaute are shown as weird characters.
Seems like there is some charset problem with ajax.
This is the only part of the application where special signs like umlaute are messed up. Everything else is fine.
I allready tried to figure out if I can escape the umlaute in the javascript (file apex_widget_4_0.js) but no success here.
Can anybody help me with this issue?
Thanks in advance,
Markus

Hi Markus,
your specified character set in your DAD is wrong. As mentioned in the installation instructions at http://download.oracle.com/docs/cd/E17556_01/doc/install.40/e15513/otn_install.htm#CHDHCBGI , Oracle APEX always requires AL32UTF8.
>
3. Locate the line containing PlsqlNLSLanguage.
The PlsqlNLSLanguage setting determines the language setting of the DAD. The character set portion of the PlsqlNLSLanguage value must be set to AL32UTF8,
regardless of whether or not the database character set is AL32UTF8. For example:Regards

Cascading Select list in tabular from

Looked at Denes example on Cascading Select Lists - http://apex.oracle.com/pls/otn/f?p=31517:119:2294401989620845.
Want to have the primary select list as an item in a region, then the secondary select list as
a column in a tabular form in the same region. Is this possible?
The Onchange event is placed in the HTML Form Element Attributes for a page item but a column on a tabular form doesn't have this.
Can the Element Attributes or Element Option Attributes be used to hold the OnChange event code?

On trial basis, i tried to implement code provided on [http://htmldb.oracle.com/pls/otn/f?p=31517:176:3223246187469527::NO|http://htmldb.oracle.com/pls/otn/f?p=31517:176:3223246187469527::NO]
I have same table DEPT & EMP HAVING same data. i created application items & processes. But My tabular form display column headings & null in each column.

SELECT COUNTRY,COUNTRY_ID FROM CAP_PLAN_COUNTRY_DETAILS'Now, how can I fix this to use the Pole Id every time the country Select List is touched..Can I just modify the query or should I add a Java Script OnChange function to handle this...
Please please help..
Thanks for reading the question...

Isn't this given in my example:
http://apex.oracle.com/pls/otn/f?p=31517:176
The second list is extended by adding:
|| 'WHERE deptno = '
|| c001to make sure it renders correctly once you call your report. In your case the second list would be extended by adding the following
apex_item.select_list_from_query(33, COUNTRY_CODE_ID, 'SELECT COUNTRY,COUNTRY_ID FROM CAP_PLAN_COUNTRY_DETAILS ' || 'WHERE POLE_ID = ' || POLE_CODE_ID
, 'style=""', 'YES', '0', '- Select Country -', 'f33_'
|| LPAD (line_no, 4, '0'), NULL, 'NO' ) COUNTRY_CODE_ID,and that should work.

Aplication item is always hidden - Shared Components > Application Items. You can create only one item and that would also be enough. For transparency purposes I said to create two. However, one will do the job.

3 Cascading Select Lists?

I've successfully implemented the AJAX cascading select list found on Denes' site, but I need to add a 3rd select list and I have not been successful with that! I've duplicated all of the steps (created a new application process, a new application item, duplicated the javascript functions using different names throughout) but I'm still missing something. My 3rd select list does not populate based on the LOV in my second select list. Is this even possible? Does the pFlowID value have anything to do with it? I tested my application process and my LOV query in the SQL Command window and both worked/returned data. Any ideas?
Thank you!

Do you mean this example:
http://apex.oracle.com/pls/otn/f?p=31517:119
It already has three select lists with a full explanation and the corresponding code.

Cascading select lists - HELP

I keep missing something from the samples i have seen on the internet on cascading select lists
I simple need one select list to determine the choices of another select list, Please use simple terms.
Thanks for your help. Please need asap.

Hi,
OK - first you should have a hidden item on page 2 that will receive the country code (I'll stick with my example, if that's ok) - say P2_COUNTRY_CODE.
Now create two select lists - say P2_STATE_CODE and P2_CITY_CODE.
It helps if you ensure that the P2_STATE_CODE list is set with a default value to ensure that the list can be filtered correctly. Create a Computation, to run in the "Before Header" process point and conditional on P2_STATE_CODE being null (Condition Type: Value of Item in Expression 1 is NULL; Expression 1: P2_STATE_CODE). Set the value to a "Static Assignment" of something that won't appear in the list (eg, ZZ for strings or -1 for numerics). You can do this on the Cities list as well if you like. Both lists should be set to display null values and have something like -Select- as the null display text.
Your States list should be created as a Select List with Submit with a List of Values based on a SQL statement:
SELECT STATE_NAME d, STATE_CODE r FROM STATES WHERE COUNTRY_CODE = :P2_COUNTRY_CODEYour Cities list is a normal Select List with a List of Values based on a SQL statement:
SELECT CITY_NAME d, CITY_CODE r FROM CITIES
WHERE COUNTRY_CODE = :P2_COUNTRY_CODE
AND (:P2_STATE_CODE = 'ZZ' OR STATE_CODE = :P2_STATE_CODE)Now, when the user selects a country from page 1, the country code is passed into P2_COUNTRY_CODE before page 2 is loaded. The default values for P2_STATE_CODE and P2_CITY_CODE are set and the lists are generated - the Cities list will display all cities for the Country selected as the States list will only show the default of ZZ and this "matches" every city in the country. Then, when the user selects an item on the States list, the page is submitted and the value for P2_STATE_CODE is updated in session. As the Cities list is based on this value, when the page is reloaded, it will be updated to filter based on the P2_COUNTRY_CODE and P2_STATE_CODE values.
The only thing you have to ensure is that P2_STATE_CODE and P2_CITY_CODE are cleared from cache when you no longer need the page - you can do this in the branch back to page 1.

thanks,
orton

Which version of Apex you r using?
If its 3.2 you can refer to this link: http://htmldb.oracle.com/pls/otn/f?p=31517:119:2521957760329919:::RP,::
if its 4.0 then enter the name of parent item in "Cascading LOV Parent Item(s)" property of the select list
and use the parent Item name in the where clause of select list query, like this.
Select name d, eid r from emp where emp_id in(select emp_id from dept_emp where dept_id = :p01_1);
where employee select list is the child and the department is the parent select list.
Thanks

Cascade Select list with Tabular Form

Hi,
I am trying to implement Cascade Select List functionality on a tabular form where users should be able to add multiple rows. The data should be saved to a temporary stage area, where users can review the data prior to saving to the table. Very similar to the shopping cart where one can Delete/Update rows by record. I believe there is a way to do it via APEX Collections. If anyone has an example it would definitely help. FYI, Running on APEX 3.2, so no built in cascade functionality.
Thank you,
Chandu

If you received a reply or figured out how to do this, can post? I need to implement exact same functionality and have not figured out how to do so. Have pinged Denes K. for source code on his demo app but not yet received response. Can this be done using wizard tab form or does it have to be a manually tab form?
