Using EL to get values from View Objects

Hello again!
I' m using jdev 11.1.1.4.0, with adf and business components
Is there any way i can get a value to an af:outputText from a view object's field without
a) having to expose all fields that I need in bindings tab?
b) having to declare all fields to a backing bean
I have a statistical table with about 30 numbers in a record and it would make my project impossible to follow!
Some EL on the af:outputText with a parameter to a function on my backing bean, would sound perfect, but I've read that it's impossible...
Any clues?
Thank you for your efforts!
Nikos

I did not understand you.
will the drag and drop your attribute on your page will solve your problem?
or do you need to create attributeValues biding for single attribute? if yes do the following:
1- From your page, right click and select Go to Page Definition.
2- From the binding section, click the plus green icon to create a new control biding, and choose attributeValues from the list.
3- select your data source from the list or create a new one, then select the attribute you need.
4- now you have a biding, and you can set the value for your output text.
value =#{biding.yourAttribute.inputValue}

  • Getting data from view object into backing bean

    Hi,
    My requirement is explained below -
         I have a ADF editable table in a jsf page which is connected to backend database table. In the table there are 6 columns and only 2 are editable. So when user inputs a value in first input column an event is triggered such that the data for all the remaining columns should be fetched from another database table.
    Typically if we are not using ADF development environment. We would have had a simple business method which creates the sql query by taking the input from textbox with simple where clause and I would have got the data. I am not getting any idea how to do this in ADF. I have the second table as view object but how to access the view object from backing bean and get data based on the input given.

    Hi,
    step 1) Expose a method on the ViewObject Impl class
    step 2) define arguments for the method as needed to identify the row to read data from
    step 3) retrieve the row from the VO that holds the data you want to add and return a HashMap with this information
    step 4) expose the method on the client interface (Java menu selection on the View Object)
    step 5) In the PageDef file, create a method binding to the method you exposed on the ViewObjectImpl
    step 6) Call the method binding from the managed bean like
    OperationBinding getDataFromVO = (OperationBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("Name of method binding);
    getDataFromVO.getParamsMap().put("name of arguments1", value1);
    getDataFromVO.getParamsMap().put("name of arguments2", value2);
    Object retData = getDataFromVO.execute();
    if(retData != null && getDataFromVO.getErrors().size()==0){
      HashMap retDataMap = (HashMap) retData;
    ... follow the rest of your logic ....

  • Can af:selectOneRadio initial selection be set to values from view object?

    Using JDeveloper 11.1.1.4
    Hi all. I have a selectOneRadio on a data entry page which works well. Now I want to (if possible) use the selectOneRadio on an edit page--setting the choice initially to the values that were stored in a database table's record (from the data entry page). I am able to retrieve the data selected in the data entry page, but I can't find anything referencing what I want to do on the edit page. Note that my selectOneRadio objects are actually on jsff's in a region on a page. I've supplied how I designed selectOneRadio on the data entry page in hopes that someone can gleen from it and tell me how to set one up on the edit page and set its initial value to the value combination stored.
    There are two columns in the data displayed (example):
    Short Format / Text
    Short Format / Comma Delimited
    Long Format / Text
            <af:selectOneRadio value="#{bindings.Pay_File_Data_FmtVO1.inputValue}"
                               shortDesc="#{bindings.Pay_File_Data_FmtVO1.hints.tooltip}" id="sor1"

              <f:selectItems value="#{bindings.Pay_File_Data_FmtVO1.items}" id="si111"/>
            </af:selectOneRadio>
    public class FileTypesBean {
        String fileFormat = null;
        String dataFormat = null;
        public BindingContainer getBindings() {
            return BindingContext.getCurrent().getCurrentBindingsEntry();
        public void getFileTypesSelection(ActionEvent actionEvent) {
            fileFormat =
                    (String)resolveExpression("#{bindings.Pay_File_Data_FmtVO1.attributeValue}");
            dataFormat =
                    (String)resolveExpression("#{bindings.Pay_File_Data_FmtVO1.attributeValues[1]}");
            //System.out.println("dataFormat = " + dataFormat);
            // now put in ParamsBean for use
            AdfFacesContext afci = AdfFacesContext.getCurrentInstance();
            ParamsBean params =(ParamsBean)afci.getPageFlowScope().get("paramsBean") ;
            params.setFileTypeParam(fileFormat);
            params.setFileDataTypeParam(dataFormat);

    in the amimpl have an edit method, get the value you want to set and set that value for your af:selectOneRadio, row.setAttribute(PayFileDataFmtVO1, value);

  • Using getElementById() to get values from drop down list

    Hi, I am using Netbeans to write this program. I have this .java page that gets the url of the HtmlPage from the .properties page. And when this page is opened in the browser, there are drop down lists that have values I want to get from the user when he/she has selected, and save it to a database. I'm actually using mozilla firefox to open this page, and using firebug to inspect the drop down list element.
    I know getElementById is a javascript code, however, my friend told me to use it in the .java page. This is how part of my code looks like. What I'm not sure is how to implement getElementById() and where.
    HtmlPage pageMain =EBPage;

  • Get Value From Combo Object

    when i declare
    ===================================
    Dim vCombo As SAPbouiCOM.ComboBox
    set vCombo = oTmpForm.Items("44").Specific
    sGRSC = vCombo.Selected.Value
    'to get combo current value into variable sGRSC
    ============================================
    i always get this error message
    "Run Time Error 91 Object Variable or With Block Variable not set ".
    Am i wrong using Combo Properties. Any Suggestion ?

    Hamdi,
    U might not have set a value for the combobox.
    Set a value like this:
              oCombo.ValidValues.Add "I", "In process"
              oCombo.ValidValues.Add "H", "On Hold"
              oCombo.ValidValues.Add "C", "Completed"
              oCombo.Select 0, psk_Index
    This will set the first value ( index starts at 0 )
    as Selected.
    Later, when u pull the combobox value into a string , it will have "I".
    ===============================================
    Hope this helps.

  • Variable used in FOx formula should get value from user

    Hi Gurus,
    In my fox formula I want to multiply a keyfigure (say quantity) with a factor. For example if the factor is 10 then all records should get multiplied by 10.
    But the requirement is user shpuld be able to give the factor that should be multiplied. That is the l_factor used in the fox function should be a variable which gets value from user. I know we can give variables in filter and planning functions in IP. But can we give values in Fox formula.
    I would really appreciate the time and effort.
    Thanking you,
    Jerry Jerome

    Hello,
    May be you can try this solution.
    I think you have create a dummy character info-object(Z_Number) of same data type interget number.Create variable for Z_Number and restrict in filter(ZV_NUM).
    DATA Z_MAT TYPE 0Material.
    DATA Z_NUM TYPE Z_NUMBER.
    DATA Z_NUM_READ TYPE I.(Declate same as data type for Z_Number)
    Z_NUM = VARV(ZV_NUM).
    FORACH Z_MAT.
    Z_NUM_READ = Z_NUM.
    {Z_KF1,Z_MAT} = Z_NUM_READ * {Z_KF1,Z_MAT}.
    ENDFOR.

  • From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

    From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

    Hi,
    Use NVL or COALESCE:
    NVL (col_a, col_b)
    Returns col_a if col_a is not NULL; otherwise, it returns col_b.
    Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
    For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
    Explain, using specific examples, how you get those results from that data.
    Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

  • How to get attribute value from an object inside an object in Xpress

    Does anyone know how to get an attribute value from an object in Xpress in a workflow? I have an object structured as follows:
    <ResourceInfo accountId='mj628' tempId='3483372b787ce7dd:-5d99a0c5:130cb238483:-3600'>
    <ObjectRef type='Resource' name='Google Apps'/>
    </ResourceInfo>
    I need if possible to get the name='Google Apps', which is inside the ObjectRef, so I guess its an attribute value of an object inside an object.

    If the ResourceInfo object is accessible in a variable, i.e. named "myResInfo", you just have to check the Java API and call the relevant method:
    <invoke name='getResourceName'>
      <ref>myResInfo</ref>
    </invoke>

  • How to get values from an IFrame...

    Hi everyone. I have come to a complete stop i my project and need to ask the following: How do i get the values from an IFrame.
    Situation: I have a main.jsp page that contains an IFrame(data.jsp). Data.jsp is basically made up of a bunch of checkboxes. The state of these boxes(checked or unchecked) is determined and set by a JAVA program and the results are then stored in a StringBuffer. Contents of Stringbuffer could look something like this: <tr><input type='checkbox' name='box0' CHECKED></tr>.
    The StringBuffer in then presented in the IFrame(data.jsp) like so: <%=res.getInfo()%>
    The user should be able to check or uncheck the boxes from the main.jsp page then when pressing a submit button the changes should be stored in a DBase.
    After the submit button have been pressed i go into my Servlet's doPost() method for some basic processing. This is were the problem starts. I usally use HttpServletRequest.getParameter(String param) to get values from the main.jsp page. But these checkboxes are stored in the IFrame, so how do i go about to retrieve the values from data.jsp from the doPost() method or in some other way maybe. This is quite urgent and i hope that i have explained the scenario in enough detail.
    Any help would be greatlly apritiated.

  • How to get values from a stored package variable of type record ?

    Sir,
    In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
    What is the best way to do that ?
    Thanks
    Stephen

    Stephen,
    not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
    If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.

    exactly?
    Some databases are case sensative.Sorry posted before done.
    Also, ensure you do not have trailing spaces in one or both. I remember Oracle had this problem a few years ago using the Type 4 driver but not through ODBC.
