LOV doesn't return selected value to the base page

Hi All,
I have created an LOV based on VO. When I select value on the LOV page, it is not returning the selected value to the base page.
I am getting the error when I select any value .
Error
You are trying to access a page that is no longer active.
- The referring page may have come from a previous session. Please select Home to proceed.
Can anyone please guide me which property has to be set.
Thanks,

1> Go to the About this page* of the page and check whether page Root AM is extended or not?
If the page root AM is extended then delete the extension by jdr_util.deleteDocument or using functional Adminstartor
or
2> See in the LOV CO, if you are using the method "releaseApplicationModule"
If yes , then remove this.
Thanks,

LOV does not return value to the base page sometimes

Hi,
I have created messageLOV type items. These LOVs do return value to the base page usually. We have a user in Uruguay who is trying to use the page which has the LOVs. He says the LOV takes a long time to return to the main page after he clicks on quick select and also the value does not get populated in the main page.
We have not been facing any such problem here in India. The LOV has been tested rigorously with no issues as such.
Can you please suggest a reason why such a problem is occuring? Expecting your replies soon
Thanks,
Priya

Thiyaga, did you read the devguide or the tutorial ?
Can you please give me the inputs about the creation of LOV and it requires how many lov mappings as mandatory?
This is there in the devguideHow to identify the mapping fields of an LOV which is already existing in the base page to reproduce in a similar way and need to do a customization on top of it ?
Open the page XML and you can find the LOV mappings.Tapash

The LOV modal window could not return value to the base page

when practicing the "create1" task in tutorial, met an issue.
when create an employee, manageName is a messageLovInput and managerID is a messageTextInput.
The issue is the LOV modal window could not return value to the mangerName, but can return to managerID .
If I remove the data boud porperties of the managerName (the bc4j porperties of view name-EmpFullVO and view attribute-MgrName), the lov works fine.
What is the reason?

James I would suggest to read the LOV topic in OAF developers' guide. Lov mappings are responsible for bringing pop up values to base page in LOV.

Custom Integrator - Date Picker/LOV does not return a value to the cell

Hi,
I have configured a webADI template with a date picker in it. Though the picker is rendered when i double-click on the cell, the selected date is not populated back. Same happens for any other list of values may render in the integrator. Any suggestions on debugging this issue.

Vinayaka

I have got the LOV working now. The issue was that I had not provided the table-select-column with the interface column name. It was set to the table column name.

Help with modal dialog returning a value to the calling page

Greetings,
Apex Version: 4.1.0.0.32
What I am trying to do is to create a modal dialog that is called from a form page. The dialog will present the user with an IR report that will allow the him to select a row and return a value from that row to a field on the calling page. I have it working in Firefox, but I get an error using IE 8. I hope someone can show me why it is not working in IE.
Here is how I am doing it:
From the calling page:
Created a button
     Action: Redirect to URL
     URL Target: javascript:var rc = window.showModalDialog('f?p=&APP_ID.:70:&SESSION.::&DEBUG.:::','','resizable:yes;center:yes;dialogWidth:1000px;dialogHeight:500px;');
On the called page:
The called page is an IR report where the query returns this as one of the columns:
*(Note: I had to put a dot '.' in front of the onclick to get it to show in this thread. It is not there in my real code.)*
select
<a href="#" name="z" style="color:blue; text-decoration:underline;" .onclick="javascript:passBack(''' || LOT_NO ||''');">Select</a>' SelectThis
, column1
, column2
from sometablename;This resolves the anchor to:
<a .onclick="javascript:passBack('232158');" href="#">Select</a>Here is the Javascript function that is called from the anchor onclick:
function passBack(passVal1)
opener.document.getElementById("P75_ITEM1").value = passVal1;
close();
}When I run this in Firefox, it works as expected. I click on the button on the parent page. The modal dialog is opened and the IR report is displayed. I click on one of the links in the report and it returns the correct value back to the calling page and closes the modal dialog.
When I run it in IE8, it fails. I click on the button on the parent page. The modal dialog is opened and the IR report is displayed. I click on one of the links in the report and I get this error: “opener.document is null or not an object”.
I hope that is clear and that someone can help.
Thanks

A quick google search determines that window.opener doesn't exists when using window.showModalDialog
Suggestions range from using window.open instead of window.showModalDialog to using dialogArguments instead of window.opener
Try the following:
In the parent page define a getPopupValue() function:
function getPopupValue(){
   var dr = window.showModalDialog('f?p=&APP_ID.:70:&SESSION.::&DEBUG.:::','','resizable:yes;center:yes;dialogWidth:1000px;dialogHeight:500px;');
    if ( (dr != undefined) && (dr != '') && (dr != false) ){
     $x("P75_ITEM1").value = dr;
}Change the button url to call the function:
javascript:getPopupValue(); On the popup page change the passback function to:
function passBack(passVal1)
returnValue = passVal1;
close();
}

Apex 2.2 popup lov doesn't return chosen value

Hey,
I've built a page within one of my applications in apex 2.2 that has an item based on a Popup LOV. I have a pre-built dynamic LOV.
When I run the page the popup icon appears and I can launch the popup. The filters work, and the result set appears. However, if I attempt to click on a value, nothing happens. The window remains opened and no value is returned to the parent window. The browser window shows no sign of javascript errors.
I'm using Theme 11 and the standard popup template.
I've tried this is a different workspace, using the same lov sql etc, and it works ok!
I've tried it elsewhere in a new page within my problematic application, and the problem is replicated there too.
What could be going wrong?
Cheers,
John

Doesn't return true value .........

Hi All,
please check the following code.
password (originalPassword) from the database is : xyz
password (password) from the login page is : xyz
when I try for equality for the password :
if(originalPassword.equalsIgnoreCase(password)) {
it doesn't return true value while the password is same that is : xyz ?
I an stuck in the problem.
Please look into the code and solve my problem.
Thanks
public boolean verifyPassword(String username, String password) {
        String originalPassword=null;
        try {
            Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
           Connection con = DriverManager.getConnection("jdbc:microsoft:sqlserver://sqlserver:1433","harish","harish");
           PreparedStatement pstmt = con.prepareStatement("select password from registration where username='"+username+"'");
           //ResultSet rs = pstmt.getResultSet();
           ResultSet rs = pstmt.executeQuery();
           if(rs.next()) {
               originalPassword=rs.getString(1);
           pstmt.close();
           if(originalPassword.equalsIgnoreCase(password)) {
                          return true;
           } else {
               return false;
       } catch (Exception e){
           System.out.println("Exception: verifyPassword="+e);
           return false;
     Harish Pathak

Are you sure there's no space before or after "xyz"? Try adding some debug output to your code:
if(originalPassword.equalsIgnoreCase(password)) {
//foo
} else {
System.out.println("<" + password + "> does not match <" + originalPassword + ">");
}

Copy select value in the textfield from LOV and allow user to edit it

Hi,
I have a datablock with 20 records and each record has comments (say field_comments) fields. I would like to allow user to choose predefined comments populated from LOV (say lov_comments) and to append some extra comments after they choose the value from LOV.
I have created a LOV and added Return type “field_comments” in the column mapping properties. When user clicks on a button, LOV opens up. They select the value from the LOV and the value goes to “field_comment” field. The problem with this approach, user can’t add their comment after selecting from LOV.
I tried this way too. I created another non-visible textbox (say dummy). In the LOV, I added “dummy” field as returntype. In the dummy field, I have created “POST-CHANGE” trigger which basically says :block. field_comments = :block. Dummy.
But, the user has to click on other field to view the selected value from the LOV. The values in the “field_comments” is not updated as soon as user click on “OK” button in the LOV.
I would appreciate it if somebody could give me some input and help to solve my issue. Thank you for your help.
Thank.

Well, I tried exactly what you posted and it allowed me to SELECT from LOV and then CHANGE/APPEND new text in front of returned value in the field. It saved to the database and queried without any problems.
Is your item allowed to INSERT/UPDATE ? If not, then set "Update/Insert Allowed" properties to Yes and attach your LOV to the item and set "Validate from list" to No.
You may also see if you have any validation being performed on WHEN-VALIDATE-ITEM or POST-CHANGE trigger which will fail since you are editing the values populated from LOV.
Hope it helps!

LOV selection fails when there are validation errors on the base page

Hi
I have lovs and some other required fields on a page . If there are any validation error on one of those text fields and if I open the LOV (not related to the text fields) and tries to select
an item from the LOV search results, it doesn't do it until unless I go back to the base page and correct all the validation errors on the text fields eventhough those text fields have nothing to do with the LOV.
Any suggestion is appreciated.
Thanks
Anwar

I am on Anwar's team, and I've been dealing with the same problem, although on a different page.
The JSPX for a contrived example is below. I can provide backing bean code, if needed.
The form contains two LOVs. Both fields are required. If you leave both fields blank and click Continue, you get a red box around both fields and error messages are displayed. If you then click the magnifying glass to select from the first LOV, the LOV pop-up is rendered. However, you cannot make a selection, either by double-clicking a line item or by clicking OK (the OK button has no effect). All you can do is cancel.
Interestingly, the act of clicking the magnifying glass on the first LOV gets rid of the red box around that field. So, once you cancel out, the second LOV actually does work. If there were more than two fields on the page, that wouldn't happen. The problem seems to be that the LOV doesn't work unless there are no validation errors on the page other than for the LOV which is being invoked.
As you can see, immediate="true" is set on both LOVs. The behavior is the same whether this is true or not.
I'm left thinking there must be something obvious that we're missing... but none of us can see it.
Thanks,
KEN

Need to get the selected values from the selectManyShuttle

Hi,
I am using ADF11g newer version.
I have a selectManyShuttle and a command button. Need to insert all the selected values on the right hand side of the selectManyShuttle into a database table.
I created the selectManyShuttle with the values. Need help in getting the values on the right hand side.
<af:selectManyShuttle value="#{bindings.UserMgmtVO1.inputValue}"
id="sms2">
<f:selectItems value="#{bindings.UserMgmtVO1.items}"
id="si6"/>
</af:selectManyShuttle>
Any sample code or link is really appreicated.
Thanks

Thanks for the reply.
I am using a View Object and I dropped it as SelectManyShuttle
<af:selectManyShuttle value="#{bindings.UserMgmtVO1.inputValue}"
id="sms2"
valueChangeListener="#{POBacking.getSelectedValues}"
valuePassThru="true"
autoSubmit="true">
<f:selectItems value="#{bindings.UserMgmtVO1.items}"
id="si6"/>
</af:selectManyShuttle>
public void getSelectedValues(ValueChangeEvent valueChangeEvent) {
System.out.println("Testing Shuttle");
ArrayList list = new ArrayList(Arrays.asList(valueChangeEvent.getNewValue()));
String val = "";
String sqlStmt = "";
try {
if (list != null) {
for (int i = 0; i < list.size(); i++) {
int l = list.size() - 1;
val = list.get(l).toString(); //returns , delimited string
System.out.println(" value:" + val);
if (val != null) {
val = val.replaceAll("[\\[\\]]", ""); //remove []
StringTokenizer st = new StringTokenizer(val, ",");
int nto = st.countTokens();
for (int j = 0; j < nto; j++) {
String users = st.nextToken().trim();
System.out.println("Users:" + users);
//sqlStmt = " update xxpp_project_clip set clip_status='true', clip_seq = "+j * 10+
// " where project_id = "+rHdr.getAttribute("ProjectId") +
// " and clip_name ='"+ clip_Name +"'";
//System.out.println("sqlStmt:" + sqlStmt);
//stmt.executeUpdate(sqlStmt);
//am.getDBTransaction().commit();
//if (stmt != null)
// stmt.close();
// am.getDBTransaction().commit();
} catch (Exception ex) {
ex.printStackTrace();
I don't see the values in the list.
I gets printed as
value:[Ljava.lang.Integer;@1b10691
Users:Ljava.lang.Integer;@1b10691
how to get the individual values in the list?
Thanks

How to directly get the selected value in the dropdown

Hi Experts
    Now, in POV, i want to directly get the selected value in the dropdown. Because, the program doesn't enter the PAI before POV part. Therefore, the corresponding variable of dropdown doesn't store the selected value. That's reason why i want to find a way to directly get the selected value in the dropdown. is there any function module to do this?

you can use INITIALIZATION event which triggers first before any other events..
and u can use VRM_SET_VALUES to populate the values in the list
DATA : v TYPE vrm_values.
DATA : vw LIKE LINE OF v.
INITIALIZATION.
vw-key = '1'.
vw-text = 'ABC'.
APPEND vw TO v.
vw-key = '2'.
vw-text = 'DEF'.
APPEND vw TO v.
CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING
      id              = 'A'
      values          = v.
PARAMETERS : a TYPE c VISIBLE LENGTH 10 AS LISTBOX.

How to clear the selected values in the JCombobox

Hi All,
Can you please tell - how to clear the selected values in the JCombobox
I have four dropdowns in my application, When I click "CLEAR" button, what ever the values selected in the four drop downs should go off and view as "SELECT" in all the dropdowns.

In addition to the above you should also check out [Combo Box Prompt|http://www.camick.com/java/blog.html?name=combo-box-prompt] which makes it easy to display the default prompt.

I want to input two values, AWG and mils and return the value in the Days column.
In the instance of what I am showing .... AWG=2 AND mils=320 so Soak=110 ....
I want to search the columns (AWG) AND (mils) to return a value in the column (Days) for that row into cell H10 (Soak) ...
So far I have toyed with LOOKUP, INDEX and MATCH ....

SCW,
I'm sure there is a clever way to cascade functions to avoid adding an auxiliary column in your practice table, but to me it wouldn't be worth the aggravation. I would add a column that concatenates Columns A & B, AWG & mils. This column can be anywhere and would be Hidden. Let's say your new column is Column N.
In Column N, fill the body rows with:
=A&"-"&B
As good Numbers programming form would indicate, let's name the Practice Table Practices and only put the practices in that table. In another table where you do the lookup, let's call it Program, we will have the calculation/lookup.
Based on your example, I'd guess that AWG may be in Column D and mils in Column E of your Program table, and the Soak lookup in Column F. If I'm wrong, adjust the column id.
In Column F, write:
=OFFSET(Practices::I$1,MATCH(D&"-"&E, Practices::N,0)−1, 0)
The hyphen in the concatenated representation of the combination of AWG and mils is just tp make it more readable.
As I'm sure you know, you could use other approaches, but since I had you put your aux column at the end of your Practices table, OFFSET with MATCH is a clean approach. INDEX could be used too.
Here's an illustration:
