How to populate data in the data table on combo box change event

hi
i am deepak .
i am very new to JSF.
my problem is i want to populate data in the datatable on the combo box change event.
for example ---
combo box has name of the city. when i will select a city
the details of the city should populate in the datatable. and if i will select another city then the datatable should change accordingly..
its urgent
reply as soon as possible
thanks in advance

i am using Rational Application Developer to develop my application.
i am using a combo box and i am assigning cityName from the SDO.
and i am declaring a variable in the pageCode eg.
private String cityName;
public void setCityName(String cityName){
this.cityName = cityName;
public String getCityName(){
return cityName;
<h:selectOneMenu id="menu1" styleClass="selectOneMenu" value="#{pc_Test1.loginID}" valueChangeListener="#{pc_Test1.handleMenu1ValueChange}">
                    <f:selectItems
                         value="#{selectitems.pc_Test1.usercombo.LOGINID.LOGINID.toArray}" />
               </h:selectOneMenu>
               <hx:behavior event="onchange" target="menu1" behaviorAction="get"
                    targetAction="box1"></hx:behavior>
and also i am declaring a requestParam type variable named city;
and at the onChangeEvent i am writing the code
public void handleMenu1ValueChange(ValueChangeEvent valueChangedEvent) {
FacesContext context = FacesContext.getCurrentInstance();
Map requestScope = ext.getApplication().createValueBinding("#{requestScope}").getValue(context);
requestScope.put("login",(String)valueChangedEvent.getNewValue());
and also i am creating another SDO which is used to populate data in datatable and in this SDO in the where clause i am using that requestParam .
it is assigning value in the pageCode variable and in the requestParam but it is not populating the dataTable. i don't no why??
it is possible that i may not clear at this point.
please send me the way how my problem can be solved.
thanks in advance

  • How to populate rows in the detail table of a form from another table.

    please can someone help me here:
    i have a master/detail page. the master data is created and then i would like to do this: when one goes to the detail page (when first created), i would like somehow to populate all the rows in the detail table from rows retrieved in another table (with conditions).
    i am new to apex so if this is a stupid question i apologise in advance!

    Hi
    Firstly, there are no stupid questions, we all start somewhere!
    However, I could do with some more detail (or even better an example on apex.oracle.com). Please can you post exactly what you have so far and what you want to achieve with simple details of the tables involved.
    It sound like you may need to create a custom process to populate the details. You say 'with conditions'... what conditions?
    Cheers

  • How to fetch records from the database into a combo box?

    Hi:
    I&acute;m really new with ABLBPM and I&acute;m trying to fetch records from the database to display them into a combo box as valid values for a presentation but I&acute;m using a dynamic method with this code:
    <em>for each row in SELECT campo1, campo2 from TABLE</em>
    <em>do</em>
    <em>solicitudes[] = [row.campo1, row.campo2]</em>
    <em>end</em>
    <em>return solicitudes
    </em>And the debugger says that SQL instructions can be used only in fuctions and procedures that are executed on the server.
    Do you know another way to do it?
    P.D. Sorry for my terrible english
    Greetings

    Hi Steve,
    Thank you, your idea is perfect, but when I try to run the screenflow where the combo should be filled I get this error:

  • How to pass the data of the dynamic table into internal table

    Hi all,
    I had designed an Dynamic table in my Online Interactive form.
    I am able to pass only the First row data into the internal table which i had created
    Now how can i pass  data of all the rows  into the  internal table.
    Needed some coding help
    Thanks
    Ajay

    Hello Ajay,
    If you have dynamic table in adobe and you want to capture all the added rows then you need to add corresponding element in the node bound to that table ui.
    when u add a row using java script in adobe form there is no corresponding element created in the backend that is ur wd node bound to the table ui. and so u only get 1 row of data back.
    try this,
    create a button in your view holding adobe form say "add rows" and on click of this button write the code to add one more element to the node bound to ur table ui of adobe form. when server side rendering occurs it will recreate the table in adobe with added row in the node and you will be able to get the data entered by user.
    Thanks,

  • How to hide committed data in the adf table

    Hi,
    I want to hide the existing data or committed data from the ADF Table when it loads.
    When I press the create button the new record only should show.
    How to do this?
    Any suggestions please.
    Thanks in advance,
    Sundar

    You can use VO.setQueryMode(ViewObjectImp.QUERY_MODE_SCAN_UNPOSTED_ENTITY_ROWS) followed by VO.executeQuery() in this case.
    http://docs.oracle.com/cd/E23549_01/apirefs.1111/e10653/oracle/jbo/ViewObject.html#QUERY_MODE_SCAN_UNPOSTED_ENTITY_ROWS
    alternatively you can also iterate over the rowset and check the entity state of the current row to be STATUS_NEW else remove the row from the collection.

  • DB Connect Load - "Unknow error while uploading data from the DB Table"

    Hi Experts,
    We have our BI7 system connected to Oracle DB based third party tool. The loads are performing quite well in DEV environment.
    I would like to know, how we transport DB Connect datasources to Quality systems? Any different process to be followed for DB Connect datasources?
    At present the connections between BI Quality and the third party quality systems are established. We transported the DataSource from BI DEV system to BI quality system, but on trigerring an infopackage we are not able to perform loads. It prompts - "Unknow error while uploading data from the DB Table".
    Also on comparing the DataSources in DEV system and Quality system there are no fields in "Proposal" tab of datasource in Quality system. Also I cannot change or activate Datasource in Quality system as we dont have change access in quality.
    Please advice.
    Thanks,
    Abhijit

    Hi,
    Sorry for bumping an old thread ....
    Did this issue get ever get resolved?
    I am facing the same one. The loads work successfully in Dev. The transport for DBConnect DS also moved in successfully.
    One strange this is that DB User for dev did not automatically change to db user from quality when I transported the DBConnect datasource. DBCon DS still shows me the DB User from Dev in Quality system
    I get "Unknown Error" whenever I trigger the data package.

  • How to fetch the data & display the data if fields got the same name in alv

    hi frnds, i need ur help.
    how to fetch the data & display the data if fields got the same name in alv grid format.
    thanks in advance,

    9321043028

    Refer the url :
    http://abapexpert.blogspot.com/2007/07/sap-list-viewer-alv.html
    Go thru the guide for OOPs based ALV.
    Use SET_TABLE_FOR_FIRST_DISPLAY to display the table:
    CALL METHOD grid->set_table_for_first_display
     EXPORTING
    I_STRUCTURE_NAME = 'SFLIGHT'     “Structure data
    CHANGING
    IT_OUTTAB = gt_sflight.          “ Output table
    You can also implement
    Full Screen ALV, its quite easy. Just pass the output table to FM REUSE_ALV_GRID_DISPLAY. 
    For controlling and implementing the FS-ALV we have to concentrate on few of the components as follows :
    1. Selection of data.
    2. Prepare Layout of display list.
    3. Event handling.
    4. Export all the prepared data to REUSE_ALV_GRID_DISPLAY.

  • Best solution to automate/upload data to the GL_DAILY_RATES_INTERFACE table

    We are using Oracle Apps 11.5.10.2 and I would like to get some feedback on a proposed solution to upload Exchange rates to the GL_DAILY_RATES_INTERFACE and then populate the GL_DAILY_RATES table.
    From what I have read so far I understand that I need to do the following, to allow the GL_DAILY_RATES table to be populated:
    Use sql Loader as the tool to upload the data.
    Write a control file, with the load data command, in this example, called rates.ctl
         LOAD DATA
         APPEND
         INTO TABLE GL_DAILY_RATES_INTERFACE
         FIELDS TERMINATED BY ','
         (FROM_CURRENCY                CHAR
         ,TO_CURRENCY                CHAR
         ,FROM_CONVERSION_DATE           DATE
         ,TO_CONVERSION_DATE           DATE
         ,USER_CONVERSION_TYPE          CHAR
         ,CONVERSION_RATE                DECIMAL EXTERNAL
         ,MODE_FLAG                     CHAR)
    Provide a data file .txt or .csv for the control file to access, for this example called fxcsv.csv
         formated:
         PHP,USD,01-SEP-11,01-SEP-11,Corporate,0.01984,I
    Provide a command for sql loader that can be written into a Unix shell script. I don't have unix level access or the recent experience to perform this task.
         sqldr apps/pw contraol=rates.ctl log=rates log bad -rates.bad data-fxcsv.csv
    Create a batch file to request the fxcsv.csv file from the OANDA site for the days current rates.
    Create a Samba share for the .csv file for OANDA file to be copied from the windows environment.
    Run Program - Daily Rates Import + Calculation to populate GL_DAILY_RATES from the data in GL_DAILY_RATES_INTERFACE.
    Couple of items that I will need to address, if the above process is the correct way to make this upload work.
    The format of the OANDA file that is download from the OANDA site, will have to be modified before it can be upload by the control file.
    I am not sure the best approach to script a modification to the .csv file, but any suggestions are welcome.
    The date in the OANDA file is not formatted correctly.
    The OANDA file does not have to_conversion_date.
    The OANDA file does not have a user_conversion_type.
    The OANDA file does not have a Mode Flag for insert or delete.
    All of the above being said, is this a solid process for uploading into the GL_DAILY_RATES_INTERFACE?
    Any feedback is appreciated.

    Hi,
    Thanks for the solution. My company has assigned me similar kind of automation process. So if you could give me more input on this that would be great. You can send me further mails on the following id : [email protected] or a reply in the same forum is much appriciated. Waiting for your reply.

  • Updating data in the database table

    Can any help me in the code for updating data in the database table.
    Regards,
    Rahul

    Hi Rahul,
    A slightly longer procedure that i'm adding here...
    1.) Create the component (i'm sure you have this covered)
    2.) Next on the button click that updates the database - add an action.
    3.) double click the action so that you are taken to the methods section of the view.
    4.) next you need to add the code that is required the update the database - this will be in the form of the above two posts.
    5.) compile and test the application
    Let me know in case you need further information on how to do this with a function module or something.
    Thanks.
