Simple drop down list

I just need to display a typical drop down list with values "A", "B", and "C". When I do this with a ComboBox there is a description needed, which I do not have/want to display. How can I create this simple drop down list?

You may use A B C for the values and descriptions. I think everyone uses this solution.
Well, everyone, but SBO itself! There are normal drop down lists all over the place (e.g. look at the Activity form).
Seems like I have to live with those limitations, only I don't understand them. Maybe someone can explain this?
Still, the question is answered, thank you very much for helping.

How can I make a bound drop-down list using OAF?

Please note, this is for OAF. I am aware of the support in ADF.
I'm sorry this is such a basic question, but I've been trying for days, and I can't think of anywhere else to look for an answer.
I need a simple drop-down list, not a search. This particular list only has 10 or so items. It is based on a view containing a code value, and a description. I need all descriptions to be available at all times. Just click the arrow, and the entire list is displayed. When the user selects an entry, the code associated with the discription populates a bound attribute. Ideally, when the page is instantiated, the code value controls the text value visible in the collapsed drop-down list. Visually, it would be similar to an html <select> element.
Can someone please tell me how I can produce such a simple thing, or point me to some documentation?
Thank you.

Thank you for the excellent reference Peddi. I had played with the OAMessageChoiceBean component yesterday, but I was able to tell from your instructions that "Picklist Display Attribute" and "Picklist Value Attribute" really are not for binding to the database EO. That was the key piece of information that had me confused.
In addition to adding the messageChoice component to the page, I needed to write some code to synchronize the picklist value with the corresponding code value, which I placed in am OAFormValueBean (hidden form field) which I could then bind to my application's database EO in the controller, running in the processFormRequest procedure:
/** Synchronize the catalog code with the selected catalog name */
protected void syncCatalogValues(OAPageContext pageContext,
OAWebBean webBean, MyApplicationAMImpl am) {
OAMessageChoiceBean mcb =
(OAMessageChoiceBean) webBean.findChildRecursive("CatalogName");
OAFormValueBean cc =
(OAFormValueBean) webBean.findChildRecursive("CatalogCode");
String catalogDescription = mcb.getText(pageContext);
if (catalogDescription != null) {
String catalogCode = am.getCatalogCode(catalogDescription);
cc.setValue(pageContext, catalogCode);
Along with a little code to get the catalogCode value from the LOVVO, that's all it took.
Thanks again. This was a great help.

Populating Drop-down List in Interactive Forms for Java

Hi,all
I need to populate a drop-down list in Interactive Form.
I tried to do it by using Dynamic Properties of the drop-down
list,but didn't give nothing.At the same time I have successfully
populated a simple drop-down list(on webdynpro view),which I
replaced near my InteractiveForm.
What may be the problem?
Regards,
Michael

Use the DDL from the Web Dynpro pallette. Bind the same/ similar attribute of the DDL you used in the web Dynpro view in the interactive form also... this should work..
Thanks and Regards,
Anto.

Display pages that reacts to different values in the drop down list.

I currently did up a simple drop down list that stores values retrieved from the database. I would like the program to display pages that reacts to the selected value without the press of any button, which means, if I select any value from the drop down list, the page will be displayed according to the value selected.
Below are the codes that I did for the retrieval of data from the database.
<%
        String username = "test";
        String password = "test";
        String thinConn = "jdbc:oracle:thin:@dbdev:1521:ORCL";
        Connection conn;
        Statement stm;
        ResultSet rs;
        String baseQuery ="SELECT DISTINCT ID FROM STAFF ORDER BY ID ASC";
        try {
            conn = DriverManager.getConnection(thinConn,username,password);
            stm = conn.createStatement();
            rs = stm.executeQuery(baseQuery);
%>
<strong>Retrieve ID from Database</strong>
    <select size="1" name="dropdown">
    <%
    while (rs.next()) {
        String id = rs.getString("ID");
        out.write("<option value=\"" + id + "\">" + "level " + id + "</option>");
                conn.close();
            } catch (SQLException e) {
    %>
    </select>Would appreciate if someone might offer some help to what I have to do next

Drop-down list is crashing my interactive PDF document

Hello, I'm using LiveCycle Designer 7.0 on Windows XP.
I'm attempting to create some simple editable PDF documents for use by my security staff.
I've created the forms and most fields work correctly, except for a simple drop-down list field with about 15 choices. When the pdf is called up from Windows and the user reaches that field (either by tabbing to it or clicking on it), the entire pdf crashes; the user is booted out and the pdf closes. The "debug" option doesn't seem to fix anything.
When I test-run the pdf in Designer, the field seems to work OK. The problem is happening when we open the pdf from Windows.
I've deleted and rebuilt this field twice, with the same result.
I'm an Adobe noob and am nowhere near sophisticated enough to employ JavaScript or other behind the scenes programming; I'm just using the basic features of Designer.
Please help, I'm stuck and don't know how to troubleshoot this problem.
Thanks in advance to anyone who may be able to point me in the right direction. Remember, I'm a noob, so single syllable words are probably best.

Hello Srini,
Thanks very much for your gracious offer. I did a bit more research
yesterday after posting my issue on the forum, and based on a similar
thread, I saved my document as a static PDF instead of a dynamic PDF.
That seems to have done the trick; all fields now work correctly without
crashing.
I will still be happy to share the document with you, but my current IE8
browser is having problems with accessing the specific website; it keeps
crashing/recovering the tab. My IT department knows about this issue and
is working to address it. At any rate, since my problem seems to be
fixed, I'm sure you have other pressing matters to attend to, but thanks
again for providing support! I will be sure to come back to the forums
if I encounter any other problems I cannot resolve.

A simple process I just don't know - how to make one drop down list dependent on another.

Drop-Down List One has 17 office names. Drop-Down List Two has sub-office names associated with each of the 17 main offices. If user selects Office 3 from Drop Down List One, only sub-offices associated with Office 3 should appear as choices in Drop-Down List Two. How do I do that?

Using a variable/drop down list in header of planning layout

Dear all,
I have created a simple BPS application for purely GL planning (No CO related objects like cost centre involved). I have the following characteristics in the header of the manuel planning layout.
Business area
Chart of accounts
Company code
Currency
Currency Type
Fiscal year
Fiscal Year Variant
Fiscal year/period
Value type
Version
I have created variables for Business area, Fiscal Year, Fiscal Year Period, Posting Period and Version. The client wants either a variable or a drop down list for these characteristics in the header in the web application. When I assign a variable and put the characteristic in header, I get the error message in the web application saying header characteristic can only have a fixed value. Can someone tell me if it is possible and if so than how? I'll be very grateful for any inputs. Thanks a lot.
Regards,
Sumit

Hi,
When you create a variable, assign some values to the variable. These then become available in the drop down box. Ths first time a Web interface is called, these variable values are initial.As a result, u get the error messages. Select the variable values and then the error message should go away.
Thanks,

How to get Date value from database and display them in a drop down list?

Hello.
In my Customers table, I have a column with Date data type. I want to create a form in JSP, where visitors can filter Customers list by year and month.

Hi
What part is your biggest problem?? I am not experienced in getting data out of a database, but the way to get a variable amount of data to show in a drop down menu, i have just messed around with for some time and heres how i solved it... In my app, what i needed was, a initial empty drop down list, and then using input from a text-field, users could add elements to a Vector that was passed to a JComboBox. Heres how.
package jcombobox;
import java.awt.*;
import java.awt.event.*;
import java.util.Vector;
import javax.swing.*;
public class Main extends JApplet implements ActionListener {
    private Vector<SomeClass> list = new Vector<SomeClass>();
    private JComboBox dropDownList = new JComboBox(list);
    private JButton addButton = new JButton("add");
    private JButton remove = new JButton("remove");
    private JTextField input = new JTextField(10);
    private JPanel buttons = new JPanel();
    public Main() {
        addButton.addActionListener(this);
        remove.addActionListener(this);
        input.addActionListener(this);
        buttons.setLayout(new FlowLayout());
        buttons.add(addButton);
        buttons.add(remove);
        add(dropDownList, "North");
        add(input, "Center");
        add(buttons, "South");
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            list.addElement(new SomeClass(input.getText()));
            input.setText("");
        } else if (e.getSource() == remove) {
            int selected = dropDownList.getSelectedIndex();
            dropDownList.removeItemAt(selected);
    public void init(String[] args) {
        setSize(400,300);
        getContentPane().setLayout(new BorderLayout());
        getContentPane().add(new Main());
}And that "SomeClass" is show here
package jcombobox;
public class SomeClass {
    private String text;
    public SomeClass(String input) {
        text = input;
    public String toString() {
        return text;
}One of the things i struggled a lot with was to get the dropdown menu to show some usefull result. If the list just contains class references it will show the memory code that points to that class. Thats where the toString cones in handy. But it took me some time to figure that one out, a laugh here is welcome as it should have been obvious :-)
When the app is as simple as this one, using a <String> vector would have been easier, but this is just to demonstrate how to place classes in a vector and get some usefull info out of it, hope this answered some of your question :-)
The layout might have been easier to write, than using the toppanel created by the JApplet and then the two additional JPanels, but it was just a small app brewed together in 15 minutes. Please comments on my faults, so that i can learn of it.
If you need any of the code specified more, please let me know. Ill be glad to,

Prevent Identical Selection in Drop Down List in an Expanding Table

Hi All,
I have a 2x2 table in which the top row is a header row and the bottom row 'Row1'. Row1 Cell1 has two buttons in it, one to add a new Row1 using Javascript click instance script:
this.parent.parent.instanceManager.addInstance()
...and one to remove any Row1 using Javascript click instance script:
var rowNum = this.parent.parent.index;
this.parent.parent.instanceManager.removeInstance(rowNum);
Row1 Cell2 contains a datadropdown object. Basically, when a user adds an extra Row1, I need to prevent them from selecting a previously selected item from the dropdowndata list. I'm having trouble figuring it out because I'm trying to put together exit instance script (or should it be validate script?) that is trying to reference Row1[*]. In simpler situations where I have two fixed objects, I have just been doing this as a FormCalc exit script:
if (Object1 = Object2)
then xfa.host.messageBox("You can't select the same thing again")
and xfa.host.resetData("Object1")
endif
... which prevents the user from selecting something with the same rawvalue by alerting them, then clearing the field.
Hope this makes sense and that someone can help! Thanks in advance to all the adobe gurus out there

Hi,
Would it be possible to filter out the choices in the drop down list that have already been selected. If so you could try something like this JavaScript in the preOpen event of your drop down.
var dropDownItems = [ "abc", "def", "hij" ];
var rows = Table1.resolveNodes("Row1[*]");
for (var i = 0; i < rows.length; i++)
    var row = rows.item(i);
    if (!row.DropDownList1.isNull)
        dropDownItems = dropDownItems.filter(function(element) { return element !== row.DropDownList1.rawValue});
this.setItems(dropDownItems.join(","));
The first line initialises a variable with all the possible values and then we go though each row filtering out the ones already selected.
You will probably have to change the form object names to suit you form, but here is my sample to test the code, https://files.acrobat.com/preview/eb0256dc-af30-4f7c-9187-469ba84464a4

How to create drop-down list in Portal??

My case: I have three locations A B C(in the database) for example.
I would like to use drop-down list to show list of All, A, B, and C.
After I choose any of them, for example A, it must show all the data of that particular location and if it is All it must show data of all three locations.
By using Simple Parameter, it's just a static one but I prefer the dynamic one that get directly from the database. And I also got a problem of showing all locations by choosing All in my dropdown menu
Any idea??!?
Thank you so much.

You could try a dynamic page:<br>
<br>
&LT;html&GT;<br>
&LT;body&GT;<br>
<br>
&LT;form action="http://host.port/pls/portal/etc." method="get"&GT;<br>
&LT;select name="location"&GT;<br>
&LT;ORACLE&GT;<br>
for rec in (select loc_code, loc_name from locations union select '-1' id, 'All' loc_name from dual)<br>
loop<br>
htp.p('&LT;option value="' || rec.loc_code || '"&GT;' || rec.loc_name || '&LT;/option&GT;');<br>
end loop;<br>
&LT;ORACLE&GT;<br>
&LT;/select&GT;<br>
&LT;/form&GT;<br>
<br>
&LT;/body&GT;<br>
&LT;/html&GT;<br>
<br>
The form should then call your page with a &location=loc_code in the url. Using a page parameter and a bound variable you can access that. You may need to use a decode in your sql to deal with the All scenario:<br>
<br>
select ..... where loc_code like decode(:location, -1, loc_code, :location)<br>
<br>
Hope this helps.<br>

Fill Drop down list in Interactive form

Hello.
I am trying to display multiple values form the context of an form, so not web dynpro! I am using a valuelist object for that.
When I test the form I am only getting to see the first value of my internal table and the drop down list cannot be expanded.
If I analyse the XML I see that the items are there which I want to display.
What is the cause of this, or is this only possible with Interactive form in an Web dynpro scenario (I hope not)
Regards,
Harrie Prinsen

Hi Harrie,
As per this post, I understand that you are going to use a simple ADOBE PRINT FORM which fetches data from ECC and displays it in the form...Am I right?
See, if it is going to be a Simple PRINT FORM which is NON-INTERACTIVE in nature, I dont see the need of DROP DOWN LIST in this scenario. I think that could be the reason why always the first item of the INTERNAL TABLE is displayed all the time.
If you have an INTERACTIVE SCENARIO where the user can select an option from the drop-down, then you can go with ABAP WD/JAVA WD/ISR Adobe Interactive Forms.

Populating Drop down List in Excel Planning Layout

HI!
hopefully somebody can help me.
I have a simple planing function ( copy function: Version1 => Version2 ), Version2 the target version is a BEx Variable and a parameter of the copy planing function.
basicly i want to put a drop down list on a Excel Planing Layout to manipulate the BEx Variable (Version 2 - the target version). So that the user can fill the BEx Variable by selecting the version by the dropdown list.
In BW-BPS is quite simple -but unfortunately i dont know how it works in BW-IP.

Hello Mike,
First you create two Drop Down lists (Dimension Version, Read Mode Masterdata table) in your workbook. Now go to the Visual basic editor (alt+F11) and you will find the following code for each Drop Down list:
Public Sub DROPDOWN_22_LostFocus()
Dim lComboBoxName As String
Dim BEx1 As Object
On Error Resume Next
lComboBoxName = "DROPDOWN_22"
Set BEx1 = Application.Run("BExAnalyzer.xla!GetBEx")
Call BEx1.RaiseComboBoxChange(Parent.Name, lComboBoxName)
End Sub
Comment the last line and add a function to output the chosen value to a cell in the workbook
Public Sub DROPDOWN_22_LostFocus()
Dim lComboBoxName As String
Dim BEx1 As Object
Dim version As String
'Call Dropdown List
On Error Resume Next
lComboBoxName = "DROPDOWN_22"
Set BEx1 = Application.Run("BExAnalyzer.xla!GetBEx")
'Call BEx1.RaiseComboBoxChange(Parent.Name, lComboBoxName)
'get version
version = DROPDOWN_22.Text
'output chosen version to a cell in the workbook
Range("C801").FormulaR1C1 = version
End Sub
Now add a command range to your workbook (VAR_VALUE_1,1, <VERSION>). Thats it.
If you need further information dont hesitate to ask me!
Best regards

Triggering "exit" event of a drop-down list in all instances of a table row

I have a drop-down list in a table row with multiple instances that performs a calculation on the exit event. This calculation draws information from 2 other dropdown lists contained above in non-repeating rows of the same table.
The desired behavior is: should the user change their choices above, all instances of the drop-down list below would perform the "Exit" event script accessing the new values above.
My script is:
RowOptionalCoverage.DdlCoverageType.execEvent("exit");     this works, sort of
It only updates the first instance of RowOptionalCoverage and none of the subsequent instances. The user can "Tab" through the instances and trigger the Exit event for each instance, but this is not a reasonable solution.
I have tried using the resolveNodes method without success. I understand, using the resolveNodes method may be necessary when referencing multiple instances of an object:
this.resolveNodes("RowOptionalCoverage[*].DdlCoverageType[*]").execEvent("exit");     doesn't work
xfa.resolveNodes("RowOptionalCoverage[*].DdlCoverageType[*]").execEvent("exit");      doesn't work
No doubt, I must be using the resolveNodes incorrectly or missing something? Probably something simple.
Any advice is greatly appreciated.
Stephen

PERFECT!!! Works right out of the box!
This has opened my eyes to the essential nature of loops. My form is very large and complex and functions correctly, Yet the coding is lacking in sophistication--no loops, functions, fragments or other code efficiencies. I am teaching myself (with the help here) and I have skipped learning and using some techniques when I could things to work using the limited skill set I have.
Sometimes, I just don't "get it". After I fail a few times, I skip it and try something else. Functions are a great example. I could utilize a bunch of these if I could only write one that works. It is frustrating. If I got one to work, I know could write a ton of them. But, there is some essential part of functions I am missing that's preventing me from having my first success with them. (I think it has to do with not understanding arguments completely).
Anyway, I am overjoyed with the solution you provided and I understand it well enough to be able to use again in other situations.
Thanks again!

Error while populating drop down list with values from a database

Hi all,
I have a JSP page with a drop down list that is to be populated with values from a database.
This is the code in my JSP file:
     
         
         <% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers();
            Iterator<Integer> iterator = floornumbers.iterator(); %>
         
         <form id="floorselectionform">
              <input type="hidden" name="action" value="floorselected"/> 
              Select floor | <select name="floorselector" id="floorselector">
                   <% while (iterator.hasNext()) { %>
                   <option value="<%=iterator.next().intValue()%>"> <%=iterator.next().intValue()%> </option>
                   <% } %>
              </select>
              <input type="submit" value="Go!"/>
         </form>   The DataManager.java class simply forwards this to its respective Peer class, which has the code shown below:
      package seatplanner.model;
    import java.sql.Connection;
    import java.sql.ResultSet;
    import java.sql.SQLException;
    import java.sql.Statement;
    import java.util.ArrayList;
    /* This class handles all floor operations */
     public class FloorPeer
     /* This method returns all the floor numbers */
     public static ArrayList<Integer> getAllFloorNumbers(DataManager dataManager) {
        ArrayList<Integer> floornumbers = new ArrayList<Integer>();
        Connection connection = dataManager.getConnection();
        if (connection != null) {
          try {
            Statement s = connection.createStatement();
            String sql = "select ID from floor order by ID asc";
            try {
              ResultSet rs = s.executeQuery(sql);
              try {
                while (rs.next()) {
                  floornumbers.add(rs.getInt(1));
              finally { rs.close(); }
            finally {s.close(); }
          catch (SQLException e) {
            System.out.println("Could not get floor numbers: " + e.getMessage());
          finally {
            dataManager.putConnection(connection);
        return floornumbers;
     } The classes compile properly, but when I load this page up in Tomcat it just freezes and does not load the form. I tested the DB connection and it works fine.
What am I doing wrong in the JSP code?
Thanks for the help in advance.
UPDATE: I commented out the form, and added <%=floornumbers.size()%> right above the commented code to check if the ArrayList is indeed getting populated with the values from the database (the values are of type integer in the database). The page still freezes like before. I'm puzzled now :confused: .

Wrong usage of Iterator.

         
         <% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers();
            Iterator<Integer> iterator = floornumbers.iterator(); %>
         
         <form id="floorselectionform">
              <input type="hidden" name="action" value="floorselected"/> 
              Select floor | <select name="floorselector" id="floorselector">
                   <% while (iterator.hasNext()) {
                                Integer inte = iterator.next();
                        %>
                   <option value="<%=inte.intValue()%>"><%=inte.intValue()%></option>
                   <% } %>
              </select>
              <input type="submit" value="Go!"/>
         </form>or make use of enhanced loop as you are already using J2SE 5.0+ for avoiding confusions.

         
         <% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers(); %>
         
         <form id="floorselectionform">
              <input type="hidden" name="action" value="floorselected"/> 
              Select floor | <select name="floorselector" id="floorselector">
                   <% for(Integer inte:floornumbers) {%>
                   <option value="<%=inte.intValue()%>"><%=inte.intValue()%></option>
                   <%}%>
              </select>
              <input type="submit" value="Go!"/>
         </form>and a lot better thing would be making usage of basic Taglib provided with JSTL spec or struts spec which make life easier and simple.
something like usage of <c:forEach/> or <logic:iterate/> would be lot better without writing a single scriptlet code.
Hope that might help :)
REGARDS,
