JUCtrlListBinding -- get current value of list

Hi.
(Jdev 11,1,2 win7.)
I saw a staff code in "Oracle Fusion Developer Guide" book for get current value of listItem as below :
import oracle.adf.model.BindingContext;
import oracle.binding.BindingContainer;
import oracle.jbo.uicli.binding.JUControlBinding;
import oracle.jbo.domain.Number;
import oracle.jbo.server.ViewRowImpl;
BindingContext bindingCtx = BindingContext.getCurrent();
BindingContainer bindings = bindingCtx.getCurrentBindingsEntry();
JUControlBinding listBinding = null;
listBinding = (JUControlBinding)bindings.get("JobId");
ViewRowImpl selectedListRow = null;
selectedListRow = (ViewRowImpl)*listBinding.getSelectedValue()*; :(
String jobIdValue = (String)selectedListRow.getAttribute("JobId");
Number maxSalary = (Number)selectedListRow.getAttribute("MaxSalary");
but Jdeveloper cannot find method getSelectedValue() for listBinding .
help me please to understand correct method .!
thanks

Declare the type of <tt>listBinding</tt> variable as <tt>JUCtrlListBinding</tt> instead of <tt>JUControlBinding</tt>. The base class JUControlBinding does not contain a method getSelectedValue(), this method is defined in the subclass JUCtrlListBinding.

    You should not create checkboxes like this. Either use the APEX_ITEM.CHECKBOX2 API or change the Column Type to Simple Checkbox.

    Depends in how you are invoking/triggering the change event. Are you using DA or have you written an "onchange" event on the element?

    please anybody help me i need urgent help

    Are you working with a list or a library? In a list, you will need to handle the synchronous (ItemUpdating) event instead of the asynchronous (ItemUpdated) event in order to access the original value...but there's a catch!
    As per the table in
    this post, the BeforeProperties hashtable is not populated for list items. You can, however, access the original value using
    properties.ListItem (the line you have commented out above) in the
    ItemUpdating event.
    Confusing, I know...but hopefully that helps!

  • How to get current logon user list of biee?

    All,
    I used BIEE 10.1.3.3. I want to export current logon user list to OS file. How to do it? I know BIEE session manager can do it. But I must export session information by java or other program.

    Hi,
    You could create a procedure which stores this information at logon and updates this information at log off.
    On the 'Connection Scripts' tab of a Connection Pool you can define two sorts of scripts; 'Execute on connect' and 'Execute on disconnect'. This way you can store the user_name and the connect and disconnect in a table.
    Good Luck,

  • How to get current value of SEQUENCE without using NEXTVAL

    Hi,
    Here is my requirement. I need to provide a screen for allowing user to change the sequence # at any given instance. If I use CURRVAL, i get error 'ORA-08002 sequence EMP_NO.CURRVAL is not yet defined in this session'
    If I use NEXTVAL and then CURRVAL it works, but i loose a sequence # which i cannot afford, since it's an employee #.
    Help required in solving the problem.
    Thanks,
    Raj

    Use this...
    select last_number from user_sequences where sequence_name = '<your-sequence>'
    to get the current sequence value. However bear in mind that on a multi-user system (and which system today is not?) there may be many users firing this query, so in case of a next sequence no. allocation request fired by more thn one of them the sequences each gets will not all be this number + 1.

  • Getting Current  Stock Prices in a Numbers 08 spreadsheet

    Can anybody give me detailed instructions to get different data regarding stock market values into a Numbers 08 spreadsheet in a way that the data can be updated by a query? I searched the forum for this but could not find anything. I am looking for data like current stock value, p/e, yield , 52 week range etc.
    I can put the stock values on the dash board and that seems to be linked to Yahoo Finance but I can find no link or help articles on how to do that in Numbers 08 and to refresh the query in Numbers to get current values.
    Thanks in advance.

    Barry is right, my script was written for Numbers '09 which offer some scriptable features.
    None of them are available in Numbers '08.
    So if you really need it and have no plan to upgrade (not to iWork '09 but to its highly wished successor) I may drop the code dedicated to Numbers '09 and stop the process with the datas stored in the clipboard so that you would be able to paste them in a table by yourself.
    Let me know if you are interested by such a stripped version;
    I'm very busy so I don't wish to spent time on a project which is not clearly useful.

  • Problem in getting the current value of the drop down while calling value change listener

    I have 2 drop down list. I am trying to get the value of first drop down from other drop downs value change listener. Initially one drop down contains a default value. First time I got the value while calling the value change listener. But if I change the default value to other in the first drop down and call the value change listener of the second drop down then I got the old value in the bean. Can anyone suggest a process

    If I use the following code it gives me the current index.
                valueChangeEvent.getComponent().processUpdates(FacesContext.getCurrentInstance());
                System.out.println(valueChangeEvent.getNewValue());
    This is also giving me current index.
    BindingContainer container = BindingContext.getCurrent().getCurrentBindingsEntry();
    AttributeBinding attrIdBinding = (AttributeBinding)container.getControlBinding("PersonTypeId1");
    if(attrIdBinding.getInputValue()!=null)
                   System.out.println(attrIdBinding.getInputValue().toString());
    But at last I got some help from Shay Shmeltzer's Weblog.
    BindingContainer bindings =
                    BindingContext.getCurrent().getCurrentBindingsEntry();
                    // Get the sepecific list binding
                    JUCtrlListBinding listBinding =
                    (JUCtrlListBinding)bindings.get("PersonTypeId1");
                    // Get the value which is currently selected
                    Object selectedValue = listBinding.getSelectedValue();
                      long value =0L;
                    if(selectedValue!=null){
                        System.out.println("Sudip.. Person Type using bindings"+selectedValue.toString());
    But this returns "ViewRow [oracle.jbo.Key[300000860721156 ]]"
    300000860721156 is the original value.. Would you please help me to figure it.

  • Get/Set values from a drop down list

    I am trying to modify the http://www.netbeans.org/kb/60/web/web-jpa-part2.html so that instead of entering the data from a text field (in update & add) the values come from a drop down list from a table. I have drop down lists that are populated bothe from the DB and hard coding. When I run, I am able to see the options on the DDs. But none of the CRUD work. I think this is because my set and get for the drop down is wrong. Then again, I also have a few text fields from the original example which also don't seem to work. Here is a piece of my addButton():
            RowKey[] selectedRowKeys = getTableRowGroup1().getSelectedRowKeys();
            PaymentDetails[] pv = getSessionBean1().getPaymentVoucher();
            int rowId = Integer.parseInt(selectedRowKeys[0].getRowId());
            PaymentDetails upPV = pv[rowId];
            bankCodeDD.getSelected();
            statusDD.getSelected(); // hard coded value
          upPV.setPrepBy((String) prepByField.getText());
          PaymentDetailsController pvController = new PaymentDetailsController();
            pvController.addPaymentDetails(upPV);
            addRequest = false;
            return null;How do I set and get the values from the drop down so than it passed to my bean? When I choose a row to be updated, make changes and click Update, I get this message on my Tomcat:
    com.sun.webui.jsf.component.DropDown::The current value of component form1:deptCodeDD does not match any of the selections.
    Did you forget to reset the value after changing the options?Can someone please point me to a place which shows how I can add a default value from my DD? I tried to follow http://www.netbeans.org/kb/55/dropdowncomp.html, but unable to complete because I get an error for Options api. The auto-fix imported import org.apache.jasper.Options; But the package given in the tutorial is com.sun.webui.jsf.model.Option. My Java version is 1.6.0_07.
    private Options listOptions[];
    ...//getter setter goes here
    listOptions = new Option[noofDBRows + 1];Many Thanks!

    I don't guess what I may add.
    The contents of the table named lookup appear on the screenshot.
    cell A1 contains the string One-Piece, cell B1 contains the 'associated' value 160.
    cell A2 contains the string Two-Piece, cell B2 contains the 'associated' value 130.
    cell A3 contains the string Three-Quarter, cell B3 contains the 'associated' value 150.
    Now table Main
    In column B the cells contain a pop_up menu with four items like the ones described by Jerrold.
    In column C of the cells contain the formula :
    =IFERROR(VLOOKUP(B,Tableau 2 :: A:B,2,FALSE),"")
    I enhanced it since yesterdays because I forgot to treat the case when cell is blank in column B.
    I apologize but as I'm using my machine in French, the screenshot display the French formulas.
    I repeat that you may find useful infos in the PDFs files which we may download from the menus:
    Help > Numbers User Guide
    Help > iWork Formulas and Functions User Guide
    As you are in Stoke-on-Trent maybe your system is set to use the comma as decimal separator.
    If it's that, you must replace the comma by semi-colons in the formulas (you may see them in my screenshot).

  • Setting current values in Multiple Select List in SQL Query based Report

    Hi,
    I have a report based on a sql query that contains a multiple select list. Unfortunately I cannot get the multiple select list to display the current values (p_value) correctly. I have created a page item, :p311_current_versions, that is set using a pre-header process and it returns a value with a colon delimited format e.g. '10.1.2.1.0:10.1.2.2.0'. Then this item is used in the sql query to set the current value (p_value) of the apex_item.select_list_from_query function. However when the table is displayed, instead of having two entries, 10.1.2.1.0 and 10.1.2.2.0 selected, it has an extra entry '10.1.2.1.0:10.1.2.2.0' selected.
    Here is my code:
    select distinct a.product, a.version from (
    select distinct
    apex_item.display_and_save(2,product)||apex_item.hidden(1,env_product_id) PRODUCT,
    APEX_ITEM.SELECT_LIST_FROM_QUERY(3,decode(product, 'HTTP Server' , :p311_current_versions, version), 'SELECT distinct version d, version r FROM ebs_tech_stack where
    product ='''||PRODUCT||'''',
    decode(PRODUCT, 'HTTP Server' ,'multiple="multiple" style="width:170px"','style="width:170px"'),
    'NO') as version
    from ebs_environment_tech_stack
    where environment_id = :p311_umgebung_id) a order by a.product
    If anyone can help me figure out how to set the current values correctly I'd be really grateful!!
    Thanks in advance,
    Jean

    Jean,
    I don't think this is possible using the apex_item package. The select_list_from_query function accepts only a single value for the second parameter.

  • How to get multiple values from the list

    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?
