Concat multiple values in a queue

Hello,
I have the following problem in message mapping:
I have one target element and several values of a source structure which I collect using an If / then function. Afterwards I remove all contexts.
What I want to do now is to concat the remaining values to be filled to a single target element.
For example there are three values left in the queue (without a context change in between) and I would like to have all of them in a single field (separated by a blank).
Using the concat function it does not work of course as the exact number of elements is determined during runtime.
Is it possible to do this with standard functions or do I need to apply an advanced UDF?
Thanks for your advice.

Hi,
Here is the UDF code for the same..
While creating Advance UDF you have to select Cache as Context.
String output = "" ;
for( int i = 0; i< a.length; i++ )
output = output + a<i>;
if ( i != a.length - 1 )
output = output + " " ;
result.addValue(output);

How to read all values of a queue

Hi All,
In Message mapping I am checking condition for field value based on incoming value.
In test cases i can see the second or third occurence is getting supressed and first value fails the condition and mapping node not created.
I would like to know how to read multiple values from queue and check condition for each value and if correct value present condition should pass.
I tried all possible context changes but no luck.
Any ideas how to read all values coming .
Thanks.

How to get peoplepicker multiple value in text box?

Hi All,
How to get multiple selection people-picker value into text box while using InfoPath?
Thanks in advance!

Hi,
According to your post, my understanding is that you wanted to get peoplepicker multiple value in text box.
You can set the default value of the text box to:
eval(eval(Person, 'concat(pc:DisplayName, "; ")'), "..")
Or change XPath (advanced) to
xdMath:Eval(xdMath:Eval(../my:group/pc:Person, 'concat(pc:DisplayName, "; ")'), "..")

How to Concat multiple columns to single column at the report level

Hi All,
I have a requirement in such a way that I have to concat multiple colulmns to single column at the report level.
First of all the column I am using in my report is "X" with datatype as Integer. Now if the length of this column "X" is <8 then I have add zero's (0) before the number.
And then I have to concat with a column "Y" and then cocnat with a column "Z" and finally the datatype should be casted to CHAR.
Can anyone please let me know the logic how I can add to my column so that it satisfies all the above.
Thanks All

>Also, Another thing is if X < length of 8 Ihave to append with zero's..
>Ex: if the actual value of X is 123456 i wanted to show it as 000123456.
Try to be consistence what you said, you are looking for 8 length and above ex is 9 in length.
You need to learn many things one of those is CASE, at least do copy and also read

How to get multiple values from the list

I've a list of an item which I queried it from the database. I also created a button that will takes a selected items from the list when it was clicked. I used javabean to get the data from database.
<%     // clicked on Select District Button
Vector vselectedDistrict = new Vector();
Vector vdistrictID = new Vector();
String tmpSelectDistrict = "";
tmpSelectDistrict = request.getParameter("bSelectDistrict");
if(tmpSelectDistrict != null)
     // get multiple values from the list
     String[] selectedDistrict = request.getParameterValues("usrTDistrict");
     vselectedDistrict.clear();
     vdistrictID.clear();
     if((selectedDistrict != null) && (selectedDistrict.length != 0))
                       for(int i=0;i<selectedDistrict.length;i++)
               vselectedDistrict.addElement(selectedDistrict);
          vdistrictID = dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
          for(int i=0;i<vdistrictID.size();i++)
               out.println("district = " + selectedDistrict[i]);                         out.println("district ID= " + vdistrictID.get(i).toString());
%>
// get vdistrict from the database here......
<select name="usrTDistrict" size="5" multiple>
<%     for(int i = 0; i< vdistrict.size(); i++)
%>
     <option value="<%=vdistrict.get(i).toString()%>"><%=vdistrict.get(i).toString()%></option>
<%
%>
</select>
<input type="submit" name="bSelectDistrict" value="Select District">
Lets say the item that i selected from the list is 'Xplace' and I clicked on the Select District button,
what I got is this error message:
org.apache.jasper.JasperException: Unable to convert string 'Xplace' to class java.util.Vector for attribute usrTDistrict: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
So where is going wrong and what the message means?. Any help very much appreciated. Thanks

These are just guesses that might hopefully steer you in directions you haven't looked in yet.
I presume you used triangle brackets (< >) to avoid having the Jive Forum think it was the "italics" tag?
Are you certain this: dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
expects a Vector as its second parameter? And returns a Vector?
I don't believe you've shown how you use the javabean, or its code? Perhaps it should be rewritten to accept an array of strings instead of a Vector?

Getting all values from a queue

Hi all,
I have a queue as follows:

IF THAT dont work Inside my UDF I want to put thE CC for the b queue.
How will the loop behave then?
What will be passed to my input queue "a" and "b" when execute "all values on context" is set.
"a" has a context and "b" doent have one.
My UDF
public static void Test(String[] a,
                                       String[] b,

I make the following steps
copy to an arraylist. add a context change in between.
copy back to string b.

Printing report that has a parameter with multiple values crashes jvm

I am using BOE XI 4.0 as an unmanaged RAS.
I am able to preview a report that has a string discrete parameter that can have multiple values. If I give it a single value. It previews fine. If I give it an empty string it prints all values which is fine. If I give it two discrete values, it displays just those two.
However, if I try printing the report to a printer:
1 parameter value - prints fine.
2 parameter values - crashes jvm
empty string parameter value - crashes jvm
I would appreciate some direction on how to do this. It works in crystal reports for eclipse.
The test jsp I am using is based off of the samples. The print test jsp is the same as the preview test with the exception of the following code differences.:
preview report.jsp code
// Create a Viewer object
CrystalReportViewer viewer = new CrystalReportViewer();
// Set the report source for the viewer to the ReportClientDocument's report source
viewer.setReportSource(clientDoc.getReportSource());
// Process the http request to view the report
viewer.processHttpRequest(request, response, getServletConfig().getServletContext(), out);
// Dispose of the viewer object
viewer.dispose();
print report jsp code
PrintReportOptions printOptions = new PrintReportOptions();
printOptions.setPrinterName("DELL");
try {
      clientDoc.getPrintOutputController().printReport(printOptions);
} catch (ReportSDKException ex1) {
      System.out.println("Message - " + ex1.getLocalizedMessage());
} catch (Exception ex2) {
      System.out.println("Message - " + ex2.getLocalizedMessage());

Multiple values from database on a single text item

i am trying to do the following
on a single text item in a form
(under form property pallete->records->number of items displayed is 5) run a triger "when-new-block-instance" with the following pl/sql statement
declare
menu_item VARCHAR2(35);
begin
select label into menu_item
from menu_options;
end;
however, once i run the form it gives me
WHEN-NEW-BLOCK-INSTANCE trigger raised unhandeled exception ORA-01422
however, if in the pl/sql statement contains only
begin
execute querry;
end;
then it works fine
The problem i beleive is the fact that the first querry retreives multiple values or recordset instead of A record.
How can i go arond this and allow the form to list all the values in this form. Eventually i will need to add conditional SQL statments and that is why just execute querry will not work.
Also, is there a way to dynamically assign a number to "number of records shown" property?
All help is very much appreciated!

Hi, Marko
I teach Forms, and I usually find a bad idea to use SQL statements directly (in particular when you can "make" Forms to do what you want).
Inside PL/SQL, a SELECT..INTO statement is supposed to select a single row, otherwise an error occurs.
EXECUTE_QUERY works.
If by "conditional SQL statements" you mean restricted (filtered) queries, you don't need to write SQL to do this.
You can set the DEFAULT_WHERE block property to a different value before using EXECUTE_QUERY, like:
SET_BLOCK_PROPERTY('your_block', DEFAULT_WHERE, 'where menu_id > 100');
And the answer to your second question is no, you cannot dynamically change the number of records a block is displaying.
You can limit the number of records your block queries from the database table using Maximum Records Fetched block property (available in Forms 6 and above, not sure about Forms 5). However, this will only work as expected if you set Query All Records to Yes.
Hope this helps,
Pedro

Automatically Selecting Values in Multiple Values Dropdown Parameters

Hi,
Is it possible to have parameter values automatically selected in a dropdown in an SSRS report? I'm using SQL Server 2008 R2 Enterprise edition. Basically what I have in mind is this: The user wants to save his parameter selections in a
table that will be available as a dropdown parameter of a report, call it
ParamUserSelection. ParamUserSelection is the first parameter of the report and other parameters depend on it.
We have two other parameters called ParamCountry and
ParamState. These are dropdown text parameters that allow multiple values to be selected. Populating the list is not a problem as I use a standard cascading parameter technique. What I'm trying to do is the following:
The user selects a value from ParamUserSelection, call it Selection1. Selection1 is stored in a table and has all the values that should be selected in ParamCountry and ParamState. In other words, it should tell these two subsequent parameters,
what values should be selected in their respective dropdowns. For example if the user selects Selection1 from ParamUserSelection, it reads the values in the database table and if it finds US and Canada for countries and CA, NY, ON for states, ParamCountry
should be populated with all the countries available in the database but should have ONLY US and Canada as selected values and ParamState should be populated with all the states in the database but should have ONLY CA, NY and ON as selected values.
If then I click on selection 2 and it has ParamCountry = US, ParamState = TX,OH in its database then again all countries and states should be in the dropdown but only US for ParamCountry and TX,OH for ParamState should be selected.
Is this possible with SSRS? I've tried using the Default Values tab with a dataset that returns all the selected values under Report Parameters Properties but this only works for the first time that I select ParamUserSelection. It appears that
if I change the value of ParamUserSelection again, the default values are not invoked.
If this is possible, please tell me how to do this as I have been struggling for a day with it.

Hi Comedian,
According to your description, you have a report with three parameters (ParamUserSelection, ParamCountry, ParamState). The available value lists of ParamCountry and ParamState are based on the selection of a value for ParamUserSelection. Now you want to
show all countries and states in their parameter dropdown list when selecting a user selection instead of only showing the cascading values. Right?
In Reporting Service, when we want a parameter to show the cascading values, we only need to set the corresponding dataset and field for Default Values in this parameter. In this scenario, if we want to show all countries and states in their dropdown list,
we just need to set another dataset for Available Values in those parameters so they can display all countries and states. We have tested your case in our local environment. Since you have done with the cascading parameters, we just give some part of steps
and screenshots for your reference:
We created two tables (dbo.Selection, dbo.states) based on your information.
Create one more dataset (named dataset2) in your report, put text below into your query:
select distinct Country from states
Create another dataset (named dataset3), put text below into your query:
select distinct State from states
Go to your ParamCountry, in Available Values, select dataset2 and Country for dataset and field.
Go to your ParamState, in Available Values, select dataset3 and State for dataset and field.
Save and preview. It looks like below:

How to use Ajax Get Multiple Values in Tabular form?

Hi All-
I am trying to use AJAX to get multiple values in tabular form by using Denes Kubicek's example in the following link -
http://apex.oracle.com/pls/otn/f?p=31517:239:9172467565606::NO:::
Basically, I want to use the drop down list to populate rest of the values on the form.
I have created the example(Ajax Get Multiple Values, application 54522) on Oracle site -
http://apex.oracle.com/pls/apex/f?p=4550:1:0:::::
Workspace: iConnect
login: demo
password: demo
I was able to duplicate his example on page 1 (home page).
However, I want to use system generate tabular form to finish this example, and was not able to populate the data correctly.
Page 2 (method 2) is the one that I am having trouble to populate the column values. When I checked application item values in Session, and the values seems to be populated correctly.
This is what I have done on this page:
1. Create an Application Process On Demand - Set_Multi_Items_Tabular2:
DECLARE
v_subject my_book_store.subject%TYPE;
v_price my_book_store.price%TYPE;
v_author my_book_store.author%TYPE;
v_qty NUMBER;
CURSOR cur_c
IS
SELECT subject, price, author, 1 qty
FROM my_book_store
WHERE book_id = :temporary_application_item2;
BEGIN
FOR c IN cur_c
LOOP
v_subject := c.subject;
v_price := c.price;
v_author := c.author;
v_qty := c.qty;
END LOOP;
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 ('<body>');
HTP.prn ('<desc>this xml genericly sets multiple items</desc>');
HTP.prn ('<item id="f04_' || :t_rownum || '">' || v_subject || '</item>');
HTP.prn ('<item id="f05_' || :t_rownum || '">' || v_price || '</item>');
HTP.prn ('<item id="f06_' || :t_rownum || '">' || v_author || '</item>');
HTP.prn ('<item id="f07_' || :t_rownum || '">' || v_qty || '</item>');
HTP.prn ('</body>');
END;
2. Create two application items - TEMPORARY_APPLICATION_ITEM2, T_ROWNUM2
3. Put the following in the Page Header:
<script language="JavaScript" type="text/javascript">
function f_set_multi_items_tabular2(pValue, pRow){
    var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=Set_Multi_Items_Tabular2',0);
if(pValue){
get.add('TEMPORARY_APPLICATION_ITEM2',pValue)
get.add('T_ROWNUM2',pRow)
}else{
get.add('TEMPORARY_APPLICATION_ITEM2','null')
    gReturn = get.get('XML');
    if(gReturn){
        var l_Count = gReturn.getElementsByTagName("item").length;
        for(var i = 0;i<l_Count;i++){
            var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
            var l_ID = l_Opt_Xml.getAttribute('id');
            var l_El = html_GetElement(l_ID);
            if(l_Opt_Xml.firstChild){
                var l_Value = l_Opt_Xml.firstChild.nodeValue;
            }else{
                var l_Value = '';
            if(l_El){
                if(l_El.tagName == 'INPUT'){
                    l_El.value = l_Value;
                }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
                    l_El.parentNode.innerHTML = l_Value;
                    l_El.parentNode.id = l_ID;
                }else{
                    l_El.innerHTML = l_Value;
    get = null;
</script>
Add the follwing to the end of the above JavaScript:
<script language="JavaScript" type="text/javascript">
function setLOV(filter, list2)
var s = filter.id;
var item = s.substring(3,8);
var field2 = list2 + item;
f_set_multi_items_tabular2(filter, field2);
4. Tabular form query:
select
"BOOK_ID",
"BOOK",
"SUBJECT",
"PRICE",
"AUTHOR",
"QTY",
"BOOK_ID" BOOK_ID_DISPLAY
from "#OWNER#"."MY_BOOK_STORE"
5. In Book_ID_DISPLAY column attribute:
Add the following code to element attributes: onchange="javascript:f_set_multi_items_tabular2(this.value,'#ROWNUM#');"
Changed to -> onchange="javascript:setLOV(this,'f03');"
Now, T_ROWNUM2 returns value as f03_0001. But, TEMPORARY_APPLICATION_ITEM2 returns as [object HTMLSelectElement]...
Please help me to see how I can populate the data with this tabular form format. Thanks a lot in advanced!!!

Updated code in Red..

Lets start with looking at what the javascript code is doing.
function f_set_multi_items_tabular(pValue, pRow){
/*This will initiate the url for the demand process to run*/
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
                          'APPLICATION_PROCESS=Set_Multi_Items_Tabular',0);
if(pValue){
    /*If there is an value than submit item name with value*/
    get.add('TEMPORARY_APPLICATION_ITEM',pValue)
    get.add('T_ROWNUM',pRow)
}else{
    /*Else set the item TEMPORARY_APPLICATION_ITEM to null*/
    get.add('TEMPORARY_APPLICATION_ITEM','null')
/*Submit the url and te returned document is of type XML*/
gReturn = get.get('XML');
if(gReturn){
    /*There is something returned*/
    var l_Count = gReturn.getElementsByTagName("item").length;
    /*For all elements of the tag item*/
    for(var i = 0;i<l_Count;i++){
      /*Get the item out of the XML*/
      var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
      /*Get the id of the item*/
      var l_ID = l_Opt_Xml.getAttribute('id');
      /*Get the element in the original page with the same id as
      **the item we have in the XML produced by the ondemand process
      var l_El = html_GetElement(l_ID);
      /*Now get the value of the item form the XML*/
      if(l_Opt_Xml.firstChild){
        var l_Value = l_Opt_Xml.firstChild.nodeValue;
      }else{
        /*There is no value*/
        var l_Value = '';
      if(l_El){
        /*There is an element with the same id as the item we are processing*/
        if(l_El.tagName == 'INPUT'){
          /*The element is an input item just set the value*/
          l_El.value = l_Value;
        }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
          /*If it is a span elment and has the class grabber
          **Then set the innerHTML of the parent to the value
          **and the id of the parent to the id
          l_El.parentNode.innerHTML = l_Value;
          l_El.parentNode.id = l_ID;
        }else{
          /*Else set the value as innerHTML*/
          l_El.innerHTML = l_Value;
get = null;
Now where it went wrong in your initial post
The XML that was returned by your XML process would be something like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_1">CSS Mastery</item>
<item id="f03_1">22</item>
<item id="f04_1">Andy Budd</item>
<item id="f05_1">1</item>
</body>
When you don't use apex_item to create your tabular form a item in the table will look like
<input id="f02_0001" type="text" value="CSS Mastery" maxlength="2000" size="16" name="f05" autocomplete="off">
Notice the id's f02_1 and f02_0001 don't match.
So to make it work the XML would have to look like

To do that simply use lpad in the ondemand process like
HTP.prn ('<item id="f02_' || lpad(:t_rownum,4,'0') || '">' || v_subject || '</item>');
HTP.prn ('<item id="f03_' || lpad(:t_rownum,4,'0') || '">' || v_price || '</item>');
HTP.prn ('<item id="f04_' || lpad(:t_rownum,4,'0') || '">' || v_author || '</item>');
HTP.prn ('<item id="f05_' || lpad(:t_rownum,4,'0') || '">' || v_qty || '</item>');
Keep in mind that the above is based on your original post and #ROWNUM# not being lpadded with zero's.

Passing Multiple Values from Multi Select

Hi,
My requirement is simple. I have created a simple Multi Select Option in parameter form and i want to send multiple selected values from the multi select option (in parameter form) to reports.
eg:
I want to send multiple countries code as input .........'US', 'CA', 'IND', 'UK'
Can i do it in Oracle 6i reports, Thanks in Advance.
Regards,
Asgar

Hi Thanks Again,
For such a nice response. I got the Lexical Where condition properly running but still getting problems in catching the multiple values to be passed from form. just i will give u an insight of wat i have done:
SQL:
SELECT ALL FROM EMPLOYEES &cond_1* -- Working FIne
in my Html Parameter Form i have an Multi Select component (the Problem is here) it is not passing more than i value from the form once i am accessing it from web or running it in paper report. In paper report layout it is not allowing me to select more than one value. but in HTML it is allowing to select multiple values but at the server end (After Parameter Form Trigger) it is giving a single value not multiple values.
In PL/SQL when i checking the length of country_id i m getting it as one.
Here is my SQL code
srw.message(10, LENGTH(:country_id_1));
:cond_1 := 'where country_id = '''|| :country_id_1 ||'''';
This is passing the condition properly to SQL but only with single value but i want to pass multiple values
I am struck in this+_
WHERE CONTRY_COLUMN IN ('USA','UAE') -- This variable you have to pass from you form...
Here as you said you gave multiple selection in your parameter form to generate report. So before generation report just prepare variable like this as it is bold above.
and pass parameter through your runtime form to the report as you pass the normal parameter...liket this i gave you example...
ADD_PARAMETER(PARAMETER_LIST_NAME,'P_CONT_PARAM',TEXT_PARAMETER,vString);
Sorry for troubling you for a small thing but please help me to solve this issue.
Thanks Again............
Asgar.

Displaying All Values from a Multiple Value Parameter

Hi,
Using XI, I have a parameter field that allows the user to enter multiple values Eg. 01, 02, 13, 14. I want to create a formula to display all the values the user has selected.
Is there a way to do this?
Thanks,
Brian

join({?Parameter},",")
creates a string with the items in your parameter separated by commas

How do I pass multiple values from a text box to an update statement

I hope this does not sound to lame. I am trying to update multiple values Like this:
Code|| Computer Desc || Computer Price || Computer Name
SEL1 || Apple macbook || 1564 || Apple Macbook Basic
SEL2 || Dell 630 || 1470 || Dell Latitude
I want to change all six values at once in one update statement based on the Code, I can't find a good tutorial/example to help me.
Can anyone point me in the right direction?
Thanks so much,
Laura

You can do conditional updates with decode or case statements e.g.
SQL> create table t as
2 select 'SEL1' as code, 'Apple macbook' as comp_desc, 1564 as comp_price, 'Apple Maxbook Basic' as comp_name from dual union
3 select 'SEL2', 'Dell 630', 1470, 'Dell Latitude' from dual
4 /
Table created.
SQL>
SQL> update t
2 set comp_desc = CASE code WHEN 'SEL1' THEN 'Test1' Else 'Test2' END,
3      comp_price = CASE code WHEN 'SEL1' THEN 1234 Else 2345 END,
4      comp_name = CASE code WHEN 'SEL1' THEN 'Test1 Name' Else 'Test2 Name' END
5 /
2 rows updated.
SQL>
SQL> select * from t
2 /
CODE COMP_DESC     COMP_PRICE COMP_NAME
SEL1 Test1               1234 Test1 Name
SEL2 Test2               2345 Test2 Name

[UIX] How To: Return multiple values from a LOV

Hi gang
I've been receiving a number of queries via email on how to return multiple items from a LOV using UIX thanks to earlier posts of mine on OTN. I'm unfortunately aware my previous posts on this are not that clear thanks to the nature of the forums Q&A type approach. So I thought I'd write one clear post, and then direct any queries to it from now on to save me time.
Following is my solution to this problem. Please note it's just one method of many in skinning a cat. It's my understanding via chatting to Oracle employees that LOVs are to be changed in a future release of JDeveloper to be more like Oracle Forms LOVs, so my skinning skills may be rather bloody & crude very soon (already?).
I'll base my example on the hr schema supplied with the standard RDBMS install.
Say we have an UIX input-form screen to modify an employees record. The employees record has a department_id field and a fk to the departments table. Our requirement is to build a LOV for the department_id field such that we can link the employees record to any department_id in the database. In turn we want the department_name shown on the employees input form, so this must be returned via the LOV too.
To meet this requirement follow these steps:
1) In your ADF BC model project, create 2 EOs for employees and departments.
2) Also in your model, create 2 VOs for the same EOs.
3) Open your employees VO and create a new attribute DepartmentName. Check selected in query. In expressions type (SELECT dept.department_name FROM departments dept WHERE dept.department_id = employees.department_id). Check Updateable always.
4) Create a new empty UIX page in your ViewController project called editEmployees.uix.
5) From the data control palette, drag and drop EmployeesView1 as an input-form. Notice that the new field DepartmentName is also included in the input-form.
6) As the DepartmentName will be populated either from querying existing employees records, or via the LOV, disable the field as the user should not have the ability to edit it.
7) Select the DepartmentId field and delete it. In the UI Model window delete the DepartmentId binding.
8) From the data controls palette, drag and drop the DepartmentId field as a messageLovInput onto your page. Note in your application navigator a new UIX page lovWindow0.uix (or similar) has been created for you.
9) While the lovWindow0.uix is still in italics (before you save it), rename the file to departmentsLov.uix.
10) Back in your editEmployees.uix page, your messageLovInput source will look like the following:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="${bindings.DepartmentId.path}"
    destination="lovWindow0.uix"/>Change it to be:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="DepartmentId"
    destination="departmentsLov.uix"
    partialRenderMode="multiple"
    partialTargets="_uixState DepartmentName"/>11) Also change your DepartmentName source to look like the following:
<messageTextInput
    id=DepartmentName
    model="${bindings.DepartmentName}"
    columns="10"
    disabled="true"/>12) Open your departmentsLov.uix page.
13) In the data control palette, drag and drop the DepartmentId field of the DepartmentView1 as a LovTable into the Results area on your page.
14) Notice in the UI Model window that the 3 binding controls have been created for you, an iterator, a range and a binding for DepartmentId.
15) Right click on the DepartmentsLovUIModel node in the UI Model window, then create binding, display, and finally attribute. The attribute binding editor will pop up. In the select-an-iterator drop down select the DepartmentsView1Iterator. Now select DepartmentName in the attribute list and then the ok button.
16) Note in the UI Model you now have a new binding called DCDefaultControl. Select this, and in the property palette change the Id to DepartmentName.
17) View the LOV pages source, and change the lovUpdate event as follows:
<event name="lovSelect">
    <compound>
        <set value="${bindings.DepartmentId.inputValue}" target="${sessionScope}" property="MyAppDepartmentId" />
        <set value="${bindings.DepartmentName.inputValue}" target="${sessionScope}" property="MyAppDepartmentName" />
    </compound>
</event>18) Return to editEmployees.uix source, and modify the lovUpdate event to look as follows:
<event name="lovUpdate">
    <compound>
        <set value="${sessionScope.MyAppDepartmentId}" target="${bindings.DepartmentId}" property="inputValue"/>
        <set value="${sessionScope.MyAppDepartmentName}" target="${bindings.DepartmentName}" property="inputValue"/>
    </compound>
</event>Thats it. Now when you select a value in your LOV, it will return 2 (multiple!) values.
A couple things to note:
1) In the messageLovInput id field we dont use the .path notation. This is mechanism for returning 1 value from the LOV and is useless for us.
2) Again in the messageLovInput we supply _uixState as an entry in the partialTargets.
3) We are relying on partial-page-refresh functionality to update multiple items on the screen.
Im not going to take the time out to explain these 3 points, but its worthwhile you learning more about them, especially the last 2, as a separate exercise.
One other useful thing to do is, in your messageLovInput, include as a last entry in the partialTargets list MessageBox. In turn locate the messageBox control on your page (if any), and supply an id=MessageBox. This will allow the LOV to place any errors raised in the MessageBox and show them to the user.
I hope this works for you :)
Cheers,
CM.

Thanks Chris,
It took me some time to find the information I needed, how to use return multiple values from a LOV popup window, then I found your post and all problems were solved. Its working perfectly, well, almost perfectly.
Im always fighting with ADF-UIX, it never does the thing that I expect it to do, I guess its because I have a hard time letting go of the total control you have as a developer and let the framework take care of a few things.
Anyway, I'm using your example to fill 5 fields at once, one of the fields being a messageChoice (a list with countries) with a LOV to a lookup table (id , country).
I return the countryId from the popup LOV window, that works great, but it doesn't set the correct value in my messageChoice . I think its because its using the CountryId for the listbox index.
So how can I select the correct value inside my messageChoice? Come to think of it, I dont realy think its LOV related...
Can someone help me out out here?
Kind regards
Ido
