How to do cascading select lists in ADF table

I have bulk update ADF table and two of the columns are select lists. For example, in a row of the table, if first select list is changed, then is it possbile to populate second list based on the value in first select list within that row?. any ideas are appreciated.

Surya

Cascading LOV's .. refer http://andrejusb.blogspot.com/2008/12/cascading-lovs-in-oracle-adf-11g-update.html
In table just set the PRR on column 2 for the column 1 component. Also set the AutoSubmit/PartialSubmit to true for the column1 component.

How to delete a selected row from adf table

Hi
I am using a ADF Table to get data from the database, i need to select a specific row and then delete it how to get
this done.
Thanks in Advance.

Or try this code:
In your backing bean:
    public void deleteRows(ActionEvent actionEvent) {
        ((AppModuleImpl)getApplicationModuleForDataControl()).deleteRowEmp();
    public static Object resolveExpression(String expression)
            try
                FacesContext facesContext = FacesContext.getCurrentInstance();
                Application app = facesContext.getApplication();
                ExpressionFactory elFactory = app.getExpressionFactory();
                ELContext elContext = facesContext.getELContext();
                ValueExpression valueExp =
                    elFactory.createValueExpression(elContext, expression, Object.class);
                return valueExp.getValue(elContext);
            catch (Exception e)
               ;// log you message here
            return null;
         * Get application module for an application module data control by name.
         * @param name application module data control name
         * @return ApplicationModule
        public static ApplicationModule getApplicationModuleForDataControl()
            return (ApplicationModule) resolveExpression("#{data.AppModuleDataControl.dataProvider}");
        }In your AppmoduleImpl:
    public void deleteRowEmp(){
        this.getEmpView1().removeCurrentRow();
        this.getDBTransaction().commit();
    }And another option is to expose the appmodule method as a client and bind to the jspx as a button.

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);
</script>

Using multiple select lists in ADF

Hi,
I am trying to use a multiple select list in my JSP page, and have a method in the ApplicationModule be called when the Struts action is called. I am following the example ADF tutorials, where the method is added to the ApplicationModule class, then dragged onto the Stuts Flow diagram (to associate it with an action).
I am able to create a dyna form bean for the page that contains the multi select as a type "java.lang.String[]" (string array). I am able get that values that were selected in a normal action's "execute" method. For example:
msf = (DynaActionForm) form;
String[] statusSelection = (String[]) msf.get("multSelectList");
However, I cannot seem to get the "multSelectList" values into a method in my Application Module class. The "multSelectList" is defined in my dynaFormBean as a String[] type. I am passing it in as an argument like the following....
public void setParams(String multSelectList[]) {
This results in the method not being called at all. I am not sure why. Does this have something to do with a String[] not being serializable??
However, if I just attempt to pass other types form items to the method, it works. For example:
public void setParams(String simpleCheckbox) {
Does anyone know how to use multiple select lists in conjunction with ADF?
P.S.
my multSelectList looks something like this:
<select name="multSelectList" multiple size="5">
<option value="ALL">Select All</option>
<option value="preferred">Preferred</option>
<option value="standard">Standard</option>
<option value="approved">Approved</option>
<option value="interim">Interim</option>
</select>

I got this working by changing the signature of the Application Module method to use ArrayList rather than String[], then you can marshal the Struts FormBean contents into an ArrayList to pass up.
To do this, subclass the DataAction by using "Go To Code" off of the context menu and then override the initializeMethodParameters() method:
protected void initializeMethodParameters(DataActionContext actionContext, JUCtrlActionBinding actionBinding)
    //Get the String Array from the Form Bean
    String[] selection = (String[])((DynaActionForm)actionContext.getActionForm()).get("multiSelect");
    //convert that to an ArrayList
    ArrayList selectionArr = new ArrayList( Arrays.asList(selection));
    //Add that object to the Arg List for the AM method
    ArrayList params = new ArrayList();
    params.add(selectionArr);
    actionBinding.setParams(params);
}

Issue with my Tabular form Cascading Select List

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.

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.

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?

Cascade select list tack few second to execute application process

Hi,
i have created some application proces fro cascading select list.
BUt when i select some value from select list then list is drpo down after click on slect value it show me drop down list value for few second .
i want when i click on selectted value then immediate relect this cascade list.
How can i resolve it.
Thanks

I am trying to guess from what I understood from your question.So correct me if I am wrong.You have set up cascading select list using ondemand process (onchange call process,retrun XML/JSON , parse the reyurn data and create/append option nodes to the child shortlist ) . The problem is that the child select list has the drop down available for a few second until the ajax HTTP request finishes completion.
Now you don't want any drop own to be available as soon as you select something.
If this is the case, add a line of code that disables the child select list as the first line of the called SJ function and enable it in the last line of the function
onchange="my_cascade_function()"
function my_cascade_function()
$x('SELECT_CHILD_ITEM').disabled=true;
//do ajax request here
//process retrun value, create select list
$x('SELECT_CHILD_ITEM').disabled=false;
}Does that help ?

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.

Help with Cascading Select List in Tabular Form

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).

Vikas,
Is your page 0 a public page or it requires authentication? I remember having the same
problem a while ago.

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.

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.
