Get Attribute values from a page and procedure exception handling?

Hi All,
I have created new page with two input attributes not based on any VO. This page is created to capture two values and pass these to an AM method upon pressing OK button. The method in AM will call a procedure with two in parameter expecting the two values captured from the above said page.
I have two questions, first one how to capture the values entered by the page in the controller class and advises me how to handle exceptions when my procedure fails.
I can not use something like this since this page is not based on a VO
String fromName = (String)vo.getCurrentRow().getAttribute("FromName");
Do I have to create a dummy VO like select '' name1, '' name2 from dual?
Thanks for the help.

Hi,
Actually you can capture the parameters on the page like this way
String test = (String)pageContext.getParameter("id of the text input bean");
Now in procedure you can take an out parameter which stores the error messages on exception
and return that out parameter in java.
and then you can throw exception on page using OAException class.
Thanks

  • How to get attribute value from standard page ?

    Hi,
    How to get attribute value from standard page ?
    String str = (String)vo.getCurrentRow().getAttrbute("RunId");
    But this value is returning a null value ....
    Can anyone help me to get this attribute value which is actually having a actual value .

    getCurrentRow() would always return null if no setCurrentRow() is used.
    Please check the page design and understand how many rows of VO are there. You can also use the following to get the row:
    vo.reset();
    vo.next();

  • Swing: when trying to get the values from a JTable inside an event handler

    Hi,
    I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
    I put two buttons (plus labels) and a JTextField . The buttons have the following role:
    One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
    So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
    do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
    I would thank you very much for the help.

  • 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 attribute values from one view to another

    HI all,
    Thx in Advance..
    I have 2 view like v1,v2.In v1 i used one attribute values from "get single attribute" method.And i need the same values in v2 screen.For this i did in v1 outbound plugs , i mentioned the parameter name . How can i get the same values in  v2.

    Hi chandru ,
    you said you declare the parameters in the Outbound Plug of V1.  now go to view V2 inbound plug Tab and creat one inbound plug
    double click on the plug name .it will navigate you to the event handeler method . Now add the outbound parameter variables in the
    parameters
    For example : V1firing the navigation plug
    a type string " defined in parameter
      wd_this->fire_out_to_view2_plg(
        a =      'ABCD'                           " string
    you can retrive the value freely in v2 inbound event handeler
    a type string " defined in parameter
    *   set single attribute
        lo_el_context->set_attribute(
          name =  `TEXT`
          value =  a )." here you will get the 'ABCD'.

  • How to get distinct values from a list and display in a ListView webpart.

    Hi,
    I have a requirement in which I need to pull unique/distinct values from a custom list and then display it via a listview webpart. Can any one suggest how this can be done.
    If possible please share the CAMEL query to fetch distinct values from a custom list.
    Thanks,
    Ankit

    Hi Ankit,
    Is there any particular reason that the values need to be shown in a list view web part?  Are you going to use that web part for filtering via web part connections?
    I ask because the enterprise site collection features include the SharePoint List Filter web part, which may accomplish what you're looking for.
    If you just need to display the values in a grid view, you might have more luck with the JavaScript Client Object Model.  Try putting the following in a text file:
    <style>
    .CustomTableClass{display:table;table-layout:fixed}
    .CustomRowClass{display:table-row;}
    </style>
    <div id="distinct_values_div" class="CustomTableClass">
    <img src="/_layouts/loading.gif" />
    </div>
    <script language="JavaScript" type="text/JavaScript">
    var siteUrl = '/sitecollection/web'; //use the actual subsite URL here
    var listName = 'mylist'; // use the actual list name here
    var field = "Title" // use the actual field you want to display here
    var divToUpdate = document.getElementById("distinct_values_div");
    var rowClass = "CustomRowClass";
    ExecuteOrDelayUntilScriptLoaded(function(){
    var clientContext = new SP.ClientContext(siteUrl);
    var web = clientContext.get_web();
    var lists = web.get_lists();
    var list = lists.getByTitle(listName);
    var camlQuery = new SP.CamlQuery();
    camlQuery.set_viewXml('<View><Query></Query><RowLimit>500</RowLimit></View>');
    this.collListItem = list.getItems(camlQuery);
    clientContext.load(collListItem,"Include ("+field+")");
    clientContext.executeQueryAsync(
    Function.createDelegate(this, this.onQuerySucceeded),
    Function.createDelegate(this, this.onQueryFailed));
    },"sp.js");
    function onQueryFailed(sender, args){
    divToUpdate.innerHTML = 'Unable to retrieve values: '+args.get_message());
    function onQuerySucceeded(sender, args){
    var allValues = [];
    var listItemEnumerator = collListItem.getEnumerator();
    divToUpdate.innerHTML = "";
    while(listItemEnumerator.moveNext()){
    var listItem = listItemEnumerator.get_current();
    if(!containsString(allValues,listItem.get_item(field)){
    var value = listItem.get_item(field);
    allValues.push(value);
    var newDiv = document.createElement("div");
    newDiv.className = rowClass;
    newDiv.innerHTML = value;
    divToUpdate.appendChild(newDiv);
    function containsString(strArray, text){
    var contains = false;
    for (var i=0; i<strArray.length; i++){
    if(strArray[i]==text){contains = true; break;}
    return contains;
    </script>
    Upload the text file to a library on the site, then add a content editor web part to a page where you want the distinct values to appear. In the content editor web part's properties, edit the Content Link so that it links directly to the text file.  This
    will cause the JavaScript to run on the page.

  • How to get the values from table region and how to set

    Hi,
    I have a requirement as Seeded Page Having One Table Region having around 8 columns, In That Item Description field is there. My Requirement is I need add one more field for that Region and assign the value depending Item Description.
    I will create one new Item in that region and will give name as Item, But how to set the values to Item Depending on Item Description.
    Is it possible to through CO Extension, If yes..Pls help how to get it.
    Thanks in Advance,
    Hanimi

    Hi Hanimi,
    1. You need to extend the VO, add a new Attribute.
    2. In VORowImpl of the extended VO, you can find the getter for your new attribute (example getItem())
    3. In this getter method you can write some code like:
    if("ABC".equals(getItemDescription())
    return "XYZ" ;

    For the textView, in the text value write the code  <%=myBean.getStr()%>
    where myBean will be your bean class and getStr() is the method in the bean class whcih returns value which needs to be displayed on the screen.

  • How to get string value from xml in JSF??

    In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

    Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
    JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

  • How to get the value from databank

    Hi,
    How to get the value from databank? and how to set the same value to visual script object?
    thanks,
    ra

    Hi,
    You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
    You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
    This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
    Thanks
