Conversion Error setting value ''{0}'' for ''{1}''

Hi
I have to populate a drop-down list on my page with the values coming from the DB.
JSF code:
<td align="right"><div id="wait" style="visibility:hidden;">Select an existing Application</div></td>
<td align="left"><div id="wait1" style="visibility:hidden;" >
<h:selectOneMenu id="exist" value="#{processApplication.selectedOwner}" styleClass="selectOneMenu">
<f:selectItems value="#{processApplication.existingOwners}"></f:selectItems>
</h:selectOneMenu>
</div>
</td>
processApplication bean:
public List<SelectItem> getExistingOwners() {                    
//existingOwners = this.getOwners();
try{
     List < SelectItem > existingOwners = new ArrayList < SelectItem > ( ) ;
     SelectItem si_0 = new SelectItem();
     SelectItem si_1 = new SelectItem();
SelectItem si_2 = new SelectItem();
     si_0.setValue("11");
     si_0.setLabel("sri");
     si_1.setValue("21");
     si_1.setLabel("ADAMS");
     existingOwners.add(si_0);
     existingOwners.add(si_1);
     logger.info("values in the list" +existingOwners.get(1).getValue());
          }catch(Exception e){
               logger.debug(e.getCause());
               e.printStackTrace();
          return existingOwners;
     public void setExistingOwners(List<SelectItem> existingOwners) {
          try{
          this.existingOwners = existingOwners;
          }catch(Exception e){
               logger.debug("%%%%");
               logger.debug(e.getCause());
               e.printStackTrace();
public String getSelectedOwner() {
     try{
     List<SelectItem> test = this.getExistingOwners();
     selectedOwner = (String)test.get(1).getValue();
     logger.debug("selected owner from the list" +selectedOwner);
     }catch(Exception e){
     logger.debug(e.getCause());
     e.printStackTrace();
     return selectedOwner;
     public void setSelectedOwner(String selectedOwner) {
          this.selectedOwner = selectedOwner;
public List<SelectItem> getExistingOwners() should actually be a call to the DB to get the list.
But since i was getting exception I tried to hard code the list in the method itself.
But , I get this exception:
logger.info values in the list 21

Earlier, I had a drop down list that was working perfectly fine.
But its values came from a Helper class and not the DB.
What is it that Iam missing or doing wrong?
Please help me.
Thanks.

Based on your example on the link that you referred to I tried to do this
fillSelectItems();
as the initialization block (I read what it means)
changed my getter method to
public List<SelectItem> getExistingOwners() { return existingOwners; }
private void fillSelectItems() {
this.existingOwners = new ArrayList<SelectItem>();
try{
     existingOwners.clear();
     List test = this.getOwners();
     SelectItem[] myitem = new SelectItem[test.size()];
     for(int i=0;i<test.size();i++) {
     Object[] arrayOne = (Object[])test.get(i);
try{
     SelectItem tmp = new SelectItem();
     tmp.setLabel(arrayOne[0].toString()+(String)arrayOne[1]);
     tmp.setValue((Integer)arrayOne[0]);
     myitem[i] = tmp;
this.existingOwners.add(myitem);
}catch(Exception e){
          logger.debug(e.getCause());
          e.printStackTrace();
     }catch(Exception e){
          logger.debug(e.getCause());
          e.printStackTrace();
Basically, I moved what I had earlier in getter method I have it now in the fillSelectItems()
Butthen, I get a NullPointerException.

  • Conversion error in Table control for Negative values

    hello all,
    Iam using table control with 6 columns and in that columns values are coming from Ztable. and out of that one column is of value which is input/output field and having negative value's also.type of that column is DEC.
    Now when i run the report dump occurs showing error message as COnversion Error.
    I think its because of negative value even the in attributes of that column i had selected With Sign checkbox.
    Now when i run the report then if in Ztable negative value is there then i want to display negative value in table control also.
    Please suggest me...

  • Currency conversion error in Update rules for 0SD_C03

    Hi All
    I have freshly installed Sales Overview cube 0SD_C03 from BI Content(3.x version) and when extracting data from datasource "2LIS_13_VDITM" there is an error "Error: Conversion foreign curr. -> local curr.: 0090000000 20080516 M -> SGD".
    Till PSA data is loading fine, there is error while loading from PSA to cube(ie. in Update Rule).
    Checked in the PSA for the errored records, all the records which have 0(zero) as amount are green and the rest of them are errored with the above message.
    When checked in the manage cube there are added records but the request is red.
    Please let me know if some one as the clue.
    Regards
    Jayant

    Hi
    You will find the transfer global settings for the source system where you are extracting the data.
    Select the source sytem, right click,go to transfer gloabal settings, (select the currencies in this)
    Then Reload the data into the cube,
    After, Reloading the data into the cube replicate the master data, and activate the mappings,and load the data.
    I think, this will work....

  • Why cannot I set value "base_directory"  for AIT?

    Hi,
    I am trying to insert MHP app into a ts and then try to recieve it on stb.
    I have a simple Xlet named HelloWorld including only one file HelloWorld.class . This xlet will display a string "Hello" on screen.
    Suppose that my xlet is stored in file system as the following:
    Test
    |----- HelloWorld.class
    |----- Folder
    |------- HelloWorld.class
    2 HelloWorlds are the same; and the whole file system will be broadcast in DSMCC OC.
    If i generate AIT including the first xlet (of Test directory) with:
    base_directory : /
    initclass: HelloWorld
    Result : GOOD, stb can run HelloWorld xlet
    If i generate AIT including the second xlet (of Folder subdirectory) with:
    base_directory: /
    initclass: Folder.HelloWorld
    or:
    base_directory: Folder
    initclass: HelloWorld
    Result: stb cannot run this Xlet.
    (I sure that the whole file system is broadcast .)
    So i think that stb just load and run xlets in root directory???
    I donnot know what causes the error ?
    How can stb load and run xlets in subdirectory?
    Thanks in advance
    Nghia.

    Sill question, but have you made sure that the path structure you are using matches the package structure for your application?
    Copying HelloWorld.class into "Folder" should not work unless the base directory is also set to "Folder". (I say this because you've indicated that the two HelloWorlds" are the same). Remember that the full name of your initial class is <package>.<className>. If this doesn't match your initclass setting then the VM will be unable to load your class.
    In general there is no particular reason why your initial class has to be at the root of the DMCC, although it is possible that the devive you are using to play out your AIT has some additional restrictions about what can be done.

  • SelectManyListbox Conversion error. Please Help

    In my application, I have a selecteManyListbox, but the selections are entirely optional.
    I have set required="false" in the component, still I see the message:
    Conversion Error setting value "" for '#{Page1.selections}'.
    The application works just fine if I select one or more options, so I do not think there is any problem in the code or the setup.
    How do I skip any conversion errors, so that I can proceed without any selections?

    Show your jsp page and source of the bean.

  • Numeric or value error: character to number conversion error

    I'm having problems inserting a value from a date picker field (DD-MON-YYYY HH MI )
    i'm submitting this value to a packaged procedure that accepts this field as VARCHAR2 .
    on the insert, i do a to_date( P_DATE, 'DD-MON-YYYY HH:MI PM' )
    and i get the numeric conversion error.
    If I change the to_date on the procedure side, I get the :could not read the end of the format mask - which I've found threads about on this site.
    I've tried using HH24 and different formats, but I get one of the two above errors on the insert.
    If I don't fill in the datepicker field at all, it works fine.
    help is appreciated !

  • Set required status for all subtypes first error

    Hello,
    While implementing OSS note 1744002 for Application Control Workflow i had the following error.
    In fact, i added a new attribute for BOR bus2201.
    When i wanted to change the status to implemented, i got the following error 'Set required status for all subtypes first'.
    Thanks,
    Meriem.

    Hi Meriem,
    Any new attribute should be added to the newly created custom SubType of the Object type BUS2201, but not Object BUS2201 itself.
    Revert the BOR BUS2201 to its original state and add the new attribute to your z<subtype>. You will no more get the error.

    Thank you for the quick reply! But the solution provided by you, it seems, has still not been able to address my issue. I ran the program at command prompt with your said parameters, but the download still gave an error in the App window.
    Also, is there some way of defining these parameters in the source code? I am keen in using NetBeans to run the program.

  • Mobile Account Error Setting Up Leopard Client, createmobileaccount error.

    Hi all. I posted this discussion under Portable Home Directories, but that is unfortunately a subcategory of Max OS X Server v10.4 Tiger and this is strictly a Leopard issues, so I'm reposting here.
    Just following up on an earlier thread regarding mobile home accounts. Thought I'd post a new entry as the other one has been "answered".
    I've just recently upgraded a slew of clients and a server to Leopard and have been trying to enable mobile accounts on existing network home accounts. When I set this as a Preference using Workgroup Manager, nothing happens on the clients. When I try to create a mobile account directly on the client while logged in as the network user, I get a standard error (The mobile account could not be created.) every time after it asks to log out and enter the user password in order to create the mobile account.
    So, I followed the steps in this thread: http://discussions.apple.com/thread.jspa?threadID=1234051&tstart=0
    For the account "leedale" logged in using a network home directory, entered the Terminal command as follows:
    /System/Library/CoreServices/ManagedClient.app/Contents/Resources/createmobileac count -vsn leedale -h /Users/leedale
    createmobileaccount built Oct 2 2007 22:44:49
    verbose output on.
    user name = "leedale"
    home path = "/Users/leedale"

    prompt for password = FALSE
    encrypt new home = FALSE
    create as external account = TRUE

    Any suggestions?

    Hi,
    The namespace you are using for creating client proxy might not be available for consumption(i.e. it might not be published) or there is no connectivity to the source system so namespace is not available.
    Try checking connection.
    Hoping it helps..
