Help with ynamic variable evaluation

Hi guys,
If someone can point me out to how to evaluate variables as
part of an expression.
for ex:
event.result.reporting.series[0].eval("y"+j+"Label");
basically how do i write the equivalent of eval in
flex/actionscript
Thanks a ton,
Pranay

Thanks Greg, saved my day................

Problem:
My flex httpservice returns an xml file in the "object"
resultFormat.
How could I get the count of all childNodes of an object in
that returned object tree.
For example, in the xml file below:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<reporting>
<series>
<title>Edge Page Views, in Page Views per
Second</title>
<xLabel>startdatetime</xLabel>
<y1Label>sum(pageviews)</y1Label>
<data>
<x>1216233600</x>
<y1>79.605</y1>
</data>
<data>
<x>1216233900</x>
<y1>78.076</y1>
</data>
</series>
<series>
<title>Total Bandwidth, in Mbits per
Second</title>
<xLabel>startdatetime</xLabel>
<y1Label>sum(egress_bytes_mbps)</y1Label>

<y3>62.77339099999999</y3>
<y4>89.30751</y4>
</data>
</series>
</reporting>
The first series element has 4 children
I am able to get the number of data elements as:
"resultObj.reporting.series[0].data.length"
How do I effectively retreive:
"resultObj.reporting.series[0].childNodes().length"
Apparently this does'nt work, I also tried Nodes, children().
Any documentation or help with this would be awesome
Thanks a ton

  • Help with Report Variables

    I have been doing battle with the SBO Customer Receivables Aging Report. I am trying to add the fields "Customer Reference" and "Creation Date" to the Repetitive area of the report with no success. All of the existing fields are variables, and the on-line help says to contact SAP support (which would be me) for help with changing variables. Does anyne have a list of these variables, or know how to define them?
    Many thanks,
    Mike.

    Hi Mike Stroud, i'm actualy also working on the customer ageing report. You also responded to my post. It was the reports one. Well, im not sure about the variables but i simply wrote a query that brings all that info and more up. But i'm having problems diplsying it. In the normal SAP report/print layout, if i  make the report based on the query it doesn't let me move the info from the repetitive area to the header....why.....can you get around this??? I then did it in the advanced layout but the first page is always wrong. What do you want to do with the variables?? what are you trying to achieve with the report because me and my coleagues have had a BIG problem with the ageing.

  • Need help with accesing variable with xpath.

    Hi All,
    I need help with xpath in "Switch" BPEL construct. Switch is used to compare value assigned to output vairable and follow one path for "Deny" and another for "Approve". The following is data type for output variable.
    <element name="processResponse">

    It works with x20:compare('Deny','Deny'). So I assumed it must be accessing the variable.
    Any help greatly appreciated.

  • Please help with Load Variables / ASP

    Hello,

  • Need help with maintaining variable choices in new session

    I have a flash app. set up with several variables. Is there a
    simple action script that will allow the user to maintain their
    choices after closing the .swf and re-launching it?
    Thanks in advance for your help.

    how are you checking if those components have been checked or
    ticked. actually, i probably don't want to know that.
    you really should be using a listener to detect when your
    components have changed and then you can use the changed method to
    set your variables and update your sharedobject.

  • A little bit of help with Bind variables please

    Hi,
    I am having a bit of trouble with bind variables I have been looking at the Dev guide and the forum to try and achieve this and it is still not happening for me, could anybody please help or point me in the right direction:
    I have created a simple PersonVO with the basic query:
    Select distinct full_name from xxml_people where person_id = :1
    In the PersonVOImpl.java I have added the method:
    public void initQuery(String personId)
    Number person = null;
    try
    person = new Number(personId);
    catch
    (Exception e){}
    setWhereClauseParam(1,person);
    executeQuery();
    Then in the PersonAM I have added the method:
    public void initPersonQuery(String personId)
    getPersonVO1().initQuery(personId);
    I then call this method in my processRequest section of my page controller:
    PersonAMImpl am = (PersonAMImpl) pageContext.getRootApplicationModule();
    String personId = "581";
    am.initPersonQuery(personId);
    When I try and run this I get the error:
    oracle.apps.fnd.framework.OAException: oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation. Statement: SELECT distinct full_name from xxml_absence_calendar where person_id = :1
    java.sql.SQLException: ORA-01006: bind variable does not exist
    Am I binding the variables correctly? Or am I making some stupid mistake?
    I am ultimately looking to create a messageChoice where the logged in user will see a list of all organisations underneath him and the one level above. I plan to do this by passing the User’s Organisation name into a VO query using the organisation as a Bind Variable. I think once I have worked out how to bind variables this should be straight forward.
    Many Thanks

    Even though the parameter binding values may be same, you should never use the positional param more than once. So always go for the format
    select distinct full_name from xxml_people where supervisor_id = :1
    UNION
    select distinct full_name from xxml_people where person_id = :2
    --Shiv

  • Help with "owned" variables concept in WPF

    I'm trying to move from WinForms to WPF and so far it's been going well. I'm struggling with the concept of updating variables from events in my code behind. It says that it was created or owned by another thread. Basically in my code all over the place I am
    having to put:
    this.Dispatcher.Invoke((Action)(() => { //Code Here }));
    Generally this is happening from an async call to update some data.
    Am I doing something fundamentally wrong in my design?
    If this snippet of code is the solution, how do I understand without the runtime compiler telling me, when I should be doing it?
    Can you explain what is happening with the Dispatcher.Invoke ((Action)(() =>{}));
    My thinking so far
    (Action) is casting the (() => {}) to an action object
    () is creating a nameless function?
    => {} define the function right here, we could have pointed to a real function if we wanted.
    Thanks for any education you can give me.

    The thing is that you can only update a UI element on the thread on which it was created. This rule applies to both Windows Forms and WPF. Please refer to the following great article for more information about the threading model in WPF:
    https://msdn.microsoft.com/en-us/magazine/cc163328.aspx. You should only create UI elements (TextBoxes, Buttons, etc.) on the UI thread and not on any background thread.
    >>Can you explain what is happening with the Dispatcher.Invoke ((Action)(() =>{}));
    The delegate (Action) that you pass to the Invoke method will be executed on the UI (or dispatcher) thread. Please refer to the above article for more information.
    >>If this snippet of code is the solution, how do I understand without the runtime compiler telling me, when I should be doing it?
    The Dispatcher has a CheckAccess() method that returns false if you are required to call the Invoke method, i.e. if the current thread doesn't have access to the UI object. You could just call this one before you call the Invoke method:
    if (!Dispatcher.CheckAccess())
    Dispatcher.Invoke(new Action(() => { }));
    Hope that helps.
    Please remember to close your threads by marking helpful posts as answer and then start a new thread if you have a new question. Please don't post several questions in the same thread.

  • Help with multiple variable

    I'm trying to write a query which pulls shipment information
    from an access database. Then it grabs the weight of each shipments
    and multiplies it by the corresponding rate depending on its weight
    class.
    I'm using the CFIF, CFELSEIF and CFSET tags to try to
    accopmlisht this, making it look something like this
    <CFIF "Shipments.weight" LT 500 >
    <cfset Shipments.rate = 7.5 >
    <CFELSEIF "Shipments.weight" GT 499 LT 1000 >
    <cfset Shipments.rate = 7 >
    <CFELSEIF "Shipments.weight" GT 999 LT 2000 >
    <cfset Shipments.rate = 6.5 >
    <CFELSEIF "Shipments.weight" GT 1999 LT 5000 >
    <cfset Shipments.rate = 5 >
    <CFELSEIF "Shipments.weight" GT 4999 >
    <cfset Shipments.rate = 3.65 >
    </CFIF>
    then in the Output tag I use this CFSCRIPT
    <cfscript>
    WriteOutput(#ACC_Report.weight#/100*#Shipments.rate#);
    </cfscript>
    It runs fine but it only seems to grab either the first or
    the second set rate variables and multiplies all the weights in the
    output query by it, inetead of logically choosing its weight class.
    Any help, perhaps I'm using the wrong logic.
    Thanks in advance

    "There's no such thing as "greater-than-ness" on string data"
    Adam, everything you said is basically true and relevant to
    the original
    poster's issue. But this line is wrong is it not? Isn't
    comparing one
    string to another and determining which is greater or lesser
    the essence
    of sorting a set of strings into an alphabetical order?
    Now, I am not sure I can remember the last time I had to
    write my own
    sort routine. But I am pretty sure when I did for sorting
    string data,
    I communally compared one to another to see which was greater
    and|or
    lesser then the other.
    To reiterate in the original post, the person is comparing
    the string
    constants "Shipments.weight" to the numbers do to the
    improper quotes,
    not the value in the Shipments.weight variable.
    Also, if one cares, the logic could be greatly simplified
    with some
    basic boolean logic. The lower range comparisons are
    unnecessary.
    <CFIF Shipments.weight LT 500 >
    <!--- weight is less then 500 --->
    <cfset Shipments.rate = 7.5 >
    <CFELSEIF Shipments.weight LT 1000 >
    <!--- weight is greater then equal to 500 it was not
    caught in first
    branch, but it is also less then 1000 --->
    <cfset Shipments.rate = 7 >
    <CFELSEIF Shipments.weight LT 2000 >
    <!--- weight is greater then equal to 1000 it was not
    caught in any
    previous branch, but it is also less then 2000--->
    <cfset Shipments.rate = 6.5 >
    <CFELSEIF Shipments.weight LT 5000 >
    <!--- weight is greater then equal to 2000 it was not
    caught in any
    previous branch, but it is also less then 5000--->
    <cfset Shipments.rate = 5 >
    <CFELSE>
    <!--- weight is greater then equal to 5000 it was not
    caught in any
    previous branch--->
    <cfset Shipments.rate = 3.65 >

  • Need help with a variable

    I ahve a report that I want to show Free to Sell stock - stock that is in the warehouse that hasn't been allocated.
    I have created a variable called Freestock which basically uses a Physical Stock quantity minus the allocated stock quantity. 
    It is currently just adding all the figures together, instead of splitting it by item, so this is wrong
    Here's the formula I'm using ;
    =Sum(<Warehouse Physical Quantity>-<Outstanding Allocated Quantity>)
    Any help would be greatly appreciated in getting this sorted
    Thanks in advance

    George,
    I am sure the formula is correct.
    It is currently just adding all the figures together, instead of splitting it by item,
    You need to pull this variable with the item object. it will automatically break the number by the Item.
    Hope this helps.

  • Help with CLASSPATH variable please

    Hi everyone!!
    Please, help to set up my classpath variable. I know I know I have guidelines in API but I don't achieve it, I'm so clumsy.
    I've formated my hard disk and installed everything again, but the classpath is wrong because I can't compile my java files.
    I've tried with this:
    C:\Program Files\Java\jdk1.5.0_06\scr.zip;C:\Program Files\Java\jdk1.5.0_06\javac.exe;C:\Program Files\Java\jdk1.5.0_06\java.exe
    I've also tried with the same lines but unnaming files (finishing with '\')
    What am I doing wrong?
    Thank you very much for your attention and help.
    Merry Christmas and Happy New Year!!
    And I hope the Three Wise Men bring you everything!!

    Please post your exact problem and the exact error message. I think you are having a problem compiling, but I am not sure. What is not working? What is the error?
    You posted a path, but if that is your Classpath, you should not have javac or java in the Classpath.

    Hi,
    The parser does not under variables directly in dml statements.u need to form a statement and the parse and execute the same...
    so the soln is
    Declare
    lv_stmt varchar2(250);
    Begin
    lv_stmt := 'Delete from '&#0124; &#0124;ls_prev_table;
    execute immediate lv_stmt;
    -- Same is the case with the insert stmt--
    End;
    This should solve ur problem.
    u could also give a direct call like
    execute immediate 'Delete from '&#0124; &#0124;ls_prev_table ;
    Note: This statement "execute immediate" holds good for oracle versions 8.x and above which makes the stmt very simple. For lower version u need to use the dbms_sql package to parse and execute the statement which has a series of statements for the same.

  • Newbie needs help with passing variables or creating flash object based on parameters

    Hello Community,
    I'm an amateur developer of Ms Access databases. In one of my applications I want to visualize the options available when reaching a certain score.
    What I'd like to get from this trial period, is a flash animation of a dartboard. Depending on an array of variables that provides the fill color (or reference thereof) the layers of the flash object will be dynamicly created, altered, or switched. The dartboard itself remains "static". I'm hoping to use 9 colors.
    I can manipulate the array any way needed. I can provide XML coding to pass the array variables. I'm just too new and untrained to incorporate this in a Edge animation or Dreamweaver.
    There is no need for interaction, once the object is created (ie no user feedback).
    Can someone point me in the right direction?
    thanks in advance,

    System.out.println(username);
    I am trying to set the public username variable to what the person enters, however since I am creating a seperate instance of it, I don't believe it will work. Any help would be very much appreciated.
    Thanks.

    I am developing in Netbeans. If I try to remove the static keyword from main(), netbeans canno't find a main to run. I have created the User class.
    Here is the main again to show what I have done.
    public static void main(String args[]) throws SQLException {
    java.awt.EventQueue.invokeLater(new Runnable() {
    public void run() {
    User user = new User();
    JFrame frame = new JFrame();
    JTextField userName = new JTextField();
    JTextField passWord = new JTextField();
    Object[] options = {"OK","CANCEL"};
    Object[] msg = {"UserName:", userName, "Password:", passWord};
    final JOptionPane op = new JOptionPane(msg, JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION){};
    JDialog dialog = op.createDialog(frame, "Please Login");
    dialog.show();
    int result = JOptionPane.OK_OPTION;
    try {
    result = ((Integer)op.getValue()).intValue();
    }catch(Exception uninitializedValue){}
    if(result == JOptionPane.OK_OPTION) {
    String userID = userName.getText();
    String passID = passWord.getText();
    user.setName(userID);
    user.setPassword(passID);
    if(!userID.equals("") && !passID.equals("")) {
    //Auth.setUserName(userID);
    //Auth.setPassword(passID);
    new Main().setVisible(true);
    }else {
    // user cancelled
    This set's the variables
    Here is the beginning of the evt that I am using to try and get the data.
    private void selButtonActionPerformed(java.awt.event.ActionEvent evt) {                                         
    Connection conn = null;
    Statement stmt3 = null;
    Statement stmt4 = null;
    ResultSet rset3 = null;
    ResultSet rset4 = null;
    String usernum = null;
    String xemu = null;
    String loc = null;
    String ustat = null;
    String manager = null;
    String dept = null;
    String Add = "Add";
    String Update = "Update";
    String groupID = "9999";
    Vector columnNames = new Vector();
    Vector data = new Vector();
    User user = new User();
    String User = user.getName();
    System.out.println(User);
    String Manager_info[] = {"managerindex", "managers", "managername"};
    String Account_info[] = {"acctypeindex", "acctype", "acctypedesc"};
    String Group_info[] = {"groupnum", "groups", "groupcode"};
    String System_info[] = {"systemindex", "systems", "systemname"};
    String Dept_info[] = {"departindex", "departments", "departname"};
    String Xemu_info[] = {"xemuindex", "xemulator", "xemudesc"};
    String Location_info[] = {"locindex", "location", "locdesc"};
    String Ustatus_info[] = {"ustatusindex", "userstatus", "ustatusdesc"};
    Date myDate = new Date();
    SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yy");
    String today = formatter.format(myDate);
    String [] str = {
    "EmpID", "Account", "System", "Type", "Status", "UserID", "Group"
    This gives me a null on the println, how can I get the data that was entered in main()?
    Thanks,
    Josh
