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.
Only one top level element is allowed in an XML document. Error processing resource 'http://apex.oracle.com/pls/apex/f?p=12...
<select><option value="0">- Select Employee (0) -</option></select><html lang="en-us" xmlns:htmld...
</code>
Please find below the list of activities I performed:
1.Created the region source
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]

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).

Multiple select lists in tabular form

Hi,
I created a tabular form with two select lists (Queries are same for both the select list and results around 300 records in the SQL).
I am getting the following error:
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
If I changed Select list to POP list, I am not getting error.
Please suggest how to user select list in this case.

Meda

Please suggest how to user select list in this case.It is not possible. There is a 32K limit on the HTML generated for select list items. (As a type of report, tabular forms are also subject to the 32K limit on the size of a report row.)
In terms of usability 200 options is about the maximum size I would consider sensible for a select list ( and for select lists in tabular forms, much, much fewer!)
Use Popup Key LOVs.

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.

Problem with cascading select lists

Hi All,
I have two select lists on a form, category and sub category. When I select the category the sub-category list gets populated and a report is displayed. When I select the sub-category the report listing re-displays limited by sub-category. Works fine.
However, when I go back and select another category, the report returns no data on the first attempt. In debug mode I note that although visually the sub-category has been reset, the session value has not, and so the report is selecting on an invalid combination of category and sub-category.
How do I get the sub-category to reset when the category changes?
I have tried an onChange javascript entry on the form attribute but it does not work since APEX inserts its own onChange before my one.
Suggestions please...thanks in advance.

Hi,
can you setup an example on apex.oracle.com which fails so that we can have a look.
Or you can use Firebug for Firefox and have a look what is sent to the server and what the response it. Check the "Console" tab. I suspect you will see an error when you trigger the refresh.

Two select lists in tabular form

I have two Select Lists which one of them depends on the another -the second one's query depends on the first one's - .....
This operation can be done in a form or a page, but how it could be done in a tabular form???
Saad

The simple answer is that to the best of my knowledge, it cannot be done because of how the tabular form works. If I understand it correctly, Tabular forms are populated completely at page load and cannot post back from items inside the form in order to refresh a list of values on the second select list. If you want to do this, you will need to build the form as a "Form and Report" page type where you have links in your report that populate a regular page form. Just tell it to put the form and the report on the same page them add a hidden page item that you set to 1 or 0 to display the form and setup the form processing so it is button tied instead of unconditional (You may have to duplicate auto processing processes).
The complex answer....there probably is a way to do this using AJAX as AJAX is good at this kind of stuff and every field in the tabular form has an HTML id of some kind....but I am not well versed enough in AJAX to give you a straight answer as to how to accomplish it. I used AJAX to do something similar to what your talking about but it was with regular page items (using a select list to populate a shuttle without a post back) and not items in a tabular form.

Dynamic Actions in Select List of Tabular Form

I have a tabular form in my application and one of the column A is Select List with lot of values. My requirement is, there is another column B in the same tabular column like Display text, which should appear when a user select A, B or C in the select list column A. Is it possible, how can I implement it?
I tried it through Dynamic Actions ->DOM Objects, but I am not sure what is the name of the Select List column value that needs to be specified, it is jst f06 or f06_???. Can someone tell me the exact steps that needs to be followed.

My mistake, Javascript (and DOM attributes/methods) are case-sensitive. The attribute in question is readOnly, not readonly
I fixed it on my example page at http://htmldb.oracle.com/pls/otn/f?p=24317:255
<script type="text/javascript">
function ro_Item(nd,a){
    var lEl = html_GetElement(nd);
    if (lEl && lEl != false){
       if(a){
      lEl.readOnly = true;
      lEl.style.background = '#cccccc';
    }else{
      lEl.readOnly = false;
      lEl.style.background = '#ffffff';
     return true;
function foo(pThis)
var lTD=pThis.parentNode;
var nextinput=lTD.nextSibling.getElementsByTagName('input')[0];
var nextnextinput=lTD.nextSibling.nextSibling.getElementsByTagName('input')[0];
if (pThis.value=="CLERK") {
ro_Item(nextinput,true);
ro_Item(nextnextinput,true);
else {
ro_Item(nextinput,false);
ro_Item(nextnextinput,false);
</script>

Can you order by label of select list in tabular form?

Imagine this scenario, you have an updateable tabular report based on a query like the following:
select emp_id
      ,ename
      ,dept_id
from employeesAnd you define the dept_id column as a query based lov, so you see a select list for departments.
select dept_name d
      ,dept_id   r
from departments
order by 1However if the user chooses to order by the department column by clicking on the heading to sort, they see the following order (note the H between A & B):
Accounting
Human Resources
BiodiversityWhich is because of the ID not being in the same order as the label
1 - Accounting
3 - Biodiversity
2 - Human ResourcesHow can I allow the user to order by the lov based column, but have it order by the label and not the reference id?
A colleague reckons she fought and lost this battle. Surely this must be a common issue? I can't seem to find any related questions.
Cheers,
ScottWe.

>
Option B: Convert to manual tabular form. Here is a sample of the report query (leave column display as at "standard report column").
select e. emp_id
      ,e.ename
      ,'<input type="hidden" value="'||d.dept_name||'" />'||APEX_ITEM.SELECT_LIST_FROM_QUERY(3,e.dept_id,'select dept_name ,dept_id from departments order by 1') dept
from employees e, departments d
where e.dept_id = d.dept_idI recently had problems when I had to apply a script to a page that used this technique: basically too many <tt>input</tt>s. Never understood why this element is used—guess it's the fact that it's "hidden". Anyway, an HTML comment works as well and is more out of the way:
select e.empno
      ,e.ename
      ,''||APEX_ITEM.SELECT_LIST_FROM_QUERY(3,e.deptno,'select dept_name ,dept_id from departments order by 1') dept
from emp e, dept d
where e.deptno = d.deptno

Need help with Hierarchical Select List

I'm trying to left-pad the entries in a select list to indicate organizational hierarchy. Here's the query:
SELECT
LPAD(' ',2*(LEVEL-1)) || ORG_NM d,
ORG_ID r
FROM
ORG_ENTITIES
START WITH ORG_ID = 901
CONNECT BY PRIOR ORG_ID = MNG_ORG_ID
ORDER BY 2;
(there are two spaces between the single quotes)
It seems to work fine from a standard SQL prompt, but it looks as if either Apex or the browser is stripping off the spaces in the padding. Can someone point out a reason? I'm using Application Express 3.0.0.00.20. Thanks.

I've used the concatenation of two items to create space between them before, and that works fine. This is an LPAD situation, however, as there is only one item.
I did try the & nbsp; in place of the literal space character. The select list strips out the & and I get some variation of the literal characters. I even tried using periods in place of spaces for the padding and that didn't work either.
Don't know what is going on.

Cascading select list in a tabular form -plz help me out

hello,
how can i implement cascading select list for filtering my tabular form report results.
Like i want to have the cascading select list's above the tabualr form report such that when i select the value in one select list, this should populate the values in other select list box(like one select list is dependent on other select list) and try to click a button say refresh, my tabular form report should be refreshed and should filter the report based on the select list value.
i want to have three select list items above my report - and these select list are dependent on one other - tats why i want to make them cascading select list.
can anyone provide me with an example of the cascading select list.
can anyone help me out with cascading select list.
thanks.

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.

CONNECT BY LEVEL = 2The filters to list the countries[2nd col of SQL, field : f33] will work on Change of Pole after a selection is made..the whole list of countries will appear with out the Pole being considered. I understand that is the case because, I have not used PoleID in the query for f33
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.

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?

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

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.

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
