Problem with CFCHART on CF10

CFCHART is not rendering on our server for some reason. We  cache to disk and are generating a .SWF file. The. SWF is in the chart cache folder ok, and can be viewed separately, however it will not render within a web page. When we view source we see this <object> tag:
<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash">
</EMBED>
</OBJECT>
but nothing appears. We tried all browsers and it's not a Flash installation issue. The graphData.cfm file never exists, and did not in previous CF versions either. Also the Images/ folder prefixing the .SWF file does not exist, but the 887962900010 0025.SWF file is in  C:\ColdFusion10\cfusion\charting\cache on our server.
Does anyone have any pointers?

Hi Wesley,
This is rather late, but we've seen the same thing frequently (and I believe can replicate it).  It's caused when you a creating a new email by copying the content of an existing one with a name space in it.
Upon copying, the link gets scrambled.  The approach we use is to copy the email in to a new template, then strip out all of the URL links and add them back in.
Thanks!

  • Problems with CFCHART

    Hi there, i'm having trouble upgrading some <CFGRAPH>
    code to <CFCHART>
    There seems to be some functionality removed which doesn't
    allow unique IDs to be passed to a URL. For example:
    In CF5 we have a page which graphs the Top 20 most viewed
    pages on our site. Each bar of the graph then links to that unique
    page when you click on it (ie.
    http://www.oursite.co.uk/page.cfm?ID=1234)
    IN MX, I cant figure out how to pass the unique ID (PGE_ID)
    of that query row to the URL attribute of <CFCHART> . Here is
    my Code:
    <CFQUERY name="qPageHitsReport"
    datasource="#Application.DSN#">
    SELECT PGE_HITCOUNT, PGE_DESC, PGE_ID
    FROM ( SELECT PGE_HITCOUNT, PGE_DESC, PGE_ID
    FROM RGUDBA.WEBPAGE
    ORDER BY PGE_HITCOUNT DESC )
    WHERE ROWNUM < 21
    </CFQUERY>
    <CFCHART chartwidth="600" chartheight="500" title="Top 20
    Pages by Page Views" format="png"
    URL="/general/info/page.cfm?pge=#PGE_ID#">
    <CFCHARTSERIES type="horizontalbar"
    query="qPageHitsReport" itemcolumn="PGE_DESC"
    valuecolumn="PGE_HITCOUNT">
    </CFCHARTSERIES>
    </CFCHART>
    With this code I get an error message:
    Error Occurred While Processing Request
    Variable PGE_ID is undefined.
    Is this not possible anymore? Surely Adobe havn't removed a
    really useful piece of functionality? ..... Or have they?
    Ally

    you can only pass dynamic values of valuecolumn ($value$),
    itemcolumn
    ($itemlabel$) and serieslabel ($serieslabel$) in the URL
    attribute of
    cfchart.
    in your case you could probably pass $itemlabel$ to a page
    that would
    then query your db to select page id based on page
    description and
    cflocate to that page...
    URL="redirectpage.cfm?pd=$itemlabel$"
    then on redirectpage.cfm:
    <CFQUERY name="getPage" datasource="#Application.DSN#">
    SELECT PGE_ID
    FROM ...
    WHERE PGE_DESC = "#URL.pd#"
    </CFQUERY>
    <cflocation url="........?pge=#getPage.PGE_ID#">
    you may want to incorporate validation routines into the
    above to
    prevent sql injection and 0 recordcount errors...

  • Problem with bar cfchart, yaxistitle distorts mouseover text

    I am having a problem with cfchart bar charts, have searched but not found a solution. If I specify any value for yaxistitle, it distorts the text that appears when you mouseover. If I don't specify yaxistitle, the text in the mouseover "bubble" looks fine. But if I specify *anything* for yaxistitle, it does not.
    Here are a couple of  snips that show the problem. This one has yaxistitle="US$ million" in the cfchart tag
    This one did not have anything for the yaxistitle parameter.
    The clients would prefer, and I agree with them, to have "Private Sector" left aligned, above the yaxistitle value and data value. I experimented with the default.xml style file, to no avail.
    Suggestions welcome!
    - Michael

    I've only encountered two instances where the PUT operation failed on certain files. One, the server does not like the particular file type, and two, when the file was open in another program.
    Other than that, I could only guess that it may have something else to do with the web server configuration and not DW.

  • Problem with Multiple Series - CFCHART

    Using CF9, trying to create a simple chart with two series.  Problem is that when there are no values, CFCHART draws a line but with values of "0".
    The first series is a set of monthly values (12 values) one for each month in 2011. The second series are also monthly values, but for 2012 YTD (Jan thru May 2012).  Range for all values is between 90 and 100, so I have it set to "scale" so you can see if year-over-year is better or worse. 
    Am trying to plot Series 1 (2011) on one line, and Series 2 on a second line.  This allows comparison of year-over-year results.  Have two QofQ, one that contains the twelve 2011 values, and one that contains the five 2012 monthly values.  X-Axis values are numbers (1-12 for 2011, and 1-5 for 2012).  However, I re-format the results using "CreateDate", so CFCHART can recognize a date, and format/display only the "months" on the chart (i.e., JAN, FEB, MAR....... DEC).   This is working, since bottom of chart shows JAN thru DEC.
    The chart displays 2011 correctly with 12 points and a line.  But for 2012, it displays the 5 points (Jan-May) with their values, then displays Jun-Dec 2012 with values of ZERO.  So on the May 2012 plot, you have this big line that runs from 90% in May, down to 0% in Jun, then 0% for the rest of 2012.  I only want it to plot the 2012 line thru May.
    If you remove the 2011 series from the CFCHART, it displays correctly, and only displays the 5 months in 2012 (Jan-May).   And if you remove the 2012 series, it displays correctly, with all 12 months in 2011.
    I just need it to display exactly like that, when two CFCHARTSERIES are used.   Even if you <CFOUTPUT> the 2012 query, you get 5 items, Jan-May.  So not sure why it want to chart 12 items for 2012, with all ZEROs for June - Dec 2012.
    Appreciate any help/advise on how to get year-over-year lines, with 12 data points for 2011 and 5 for 2012. 
    Gary

    Thanks, I found the solution doing a Google search, which led me to this Adobe forum link:
    http://forums.adobe.com/message/3304324#3304324
    which is same one you mentioned.  I was so relieved it wasn't a problem with my code, I kept testing for errors, couldn't find any.
    We are in the process of upgrading from CF7 to CF9.  We are developing on CF9, but still using CF7 in production, hopefully for only a few more weeks until we get our new CF/SQL Servers, running CF9.
    Until then, have to write two versions of the .CFM file, one that runs on CF7 servers, and one for the CF9 test servers.
    Thanks again for getting back, much appreciated.

  • Purchased ColdFusion 10: Having problem with session variables

    My Dept. has just bought CF10 and I'm finally updating my existing web app to CF10 from CF8. My First Problem with CF10 is using session variables.
    When using the lower version of CF (since CF 4 to 8) I have never had any problem setting up session variables and getting or using these variables in other pages after a successful login but with CF 10 it seems setting session variables and using them in other pages are a major problems. I'm not sure where have I done wrong in the codes.
    First I'm setting the session in my Application.cfc This way:
    <cfcomponent displayname="Application" output="true">
      <cfset THIS.Name ="MyNewApp"/>
      <cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,20,0) />
      <cfset THIS.SessionManagement ="YES"/>
      <cfset THIS.SessionTimeout = CreateTimeSpan( 0, 0, 20, 0 ) />
      <cfset THIS.SetClientCookies = false />
    <cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">
    <cfset application.Main_DSN = "TESTDB">
    <cfreturn true />
    </cffunction>
    <cffunction name="onApplicationEnd" output="false">
          <cfargument name="applicationScope" required="true">
        </cffunction>
    <cffunction name="OnSessionStart" access="public" returntype="void" output="false" hint="Fires when user session initializes.">
    <cfset session.loggedin = "NO">
    <cfset session.username = "">
    <cfset session.userrights = "">
    <cfset session.usergroup = "">
    </cffunction>
    </cfcomponent>
    After login, user is validated and set values to those session.variables:
    ........user validation codes here......................
    <cfif mylogin NEQ true>
          <cflocation url="/login/login.cfm">
          <cfabort
    <cfelse>
          <cfset session.loggedin="Yes">
          <cfset session.username="#Trim(Form.username)#">
         <CFSET qUserRights = LoginObj.getUserRights('#Trim(Form.username)#')>
         <cfset session.userrights = qUserRights><!--- it's a query --->
        <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>
            <cfloop query="qUserGroup">
               <cfset session.usergroup = user_group>
               <cfbreak>
            </cfloop>
        <!--- ****************** ???????????????????????????????????????????????????????????????????????????
        When I do cfdump in at this level, I can see that all of these session variables have been assigned to their values.
        But these session variables are not accessible from other pages. Other pages still show these session variable without its value.
        So, when I use these cfdumps in the index.cfm it is shown as they're not yet assigned with any values   ****************** --->
       <cfdump var="#session.loggedin#">
       <cfdump var="#session.username#">
       <cfdump var="#session.userright#">
       <cfdump var="#session.usergroup#">
    </cfif>
    In index.cfm, Before Login I got:
    session.loggedin = NO
    session.username = ["empty string"]
    session.userrights = ["empty string"]
    session.usergroup = ["empty string"]
    After a successful Login:
    session.loggedin = NO
    session.username = ["empty string"]
    session.userrights = ["empty string"]
    session.usergroup = ["empty string"]
    Have I done something wrong? These codes work on CF8. Please help.
    I need to mentioned:
    CF10 is in Linux and my web app is under https not http. But these session variables should be shared bentween http and https because some older application are still in http.

    On which page is the following code?
    After login, user is validated and set values to those session.variables:
    ........user validation codes here......................
    <cfif mylogin NEQ true>
          <cflocation url="/login/login.cfm">
          <cfabort
    <cfelse>

          <cfset session.username="#Trim(Form.username)#">
         <CFSET qUserRights = LoginObj.getUserRights('#Trim(Form.username)#')>
         <cfset session.userrights = qUserRights><!--- it's a query --->
        <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>
            <cfloop query="qUserGroup">

  • A problem with threads

    I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
    Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
    My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
    Thank you in advance,
    Lefty

    This was one solution from the socket programming forum, have you tried this??
    public Thread MyThread extends Thread{
         boolean active = true;          
         public void run(){
              ss.setSoTimeout(90);               
              while (active){                   
                   try{                       
                        serverSocket = ss.accept();
                   catch (SocketTimeoutException ste){
                   // do nothing                   
         // interrupt thread           
         public void deactivate(){               
              active = false;
              // you gotta sleep for a time longer than the               
              // accept() timeout to make sure that timeout is finished.               
              try{
                   sleep(91);               
              }catch (InterruptedException ie){            
              interrupt();
    }

  • Problem with Threads and a static variable

    I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
    Code functionality:
    A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
    The problem as far I understand is:
    Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
    Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
    Thanks,
    B.D.
    Code:
    private static volatile boolean bChanged = false;
    private static Thread objMainProcess;
       protected static void Init(){
            objMainProcess = new Thread() {
                public void run() {
                    while( objMainProcess == Thread.currentThread() ) {
                       GetState();
            objMainProcess.setDaemon( true );
            objMainProcess.start();
        public static void initStatusTimer(){
            if(objTimer == null)
                 objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                    public void actionPerformed( java.awt.event.ActionEvent evt){
                              SetState();
        private static void SetState(){
            if( objMainProcess == null ) return;
            synchronized( objMainProcess ) {
                bChanged = true;
                try{
                    objMainProcess.notify();
                }catch( IllegalMonitorStateException e ) {}
        private static boolean GetState() {
            if( objMainProcess == null ) return false;
            synchronized( objMainProcess ) {
                if( bChanged) {
                    SendMessage();
                    bChanged = false;
                    return true;
                try {
                    objMainProcess.wait();
                }catch( InterruptedException e ) {}
                return false;
        }

    Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
    Again as you said, There is a reason I can't call sendMessage() inside setState().
    The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
    Thanks,
    B.D.

  • Problem with threads running javaw

    Hi,
    Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
    troy.

    troy,
    Try and post a minimum code sample of your app which
    does not work.
    When using javaw, make sure you redirect the standard
    error and standard output streams to file.
    Graeme.Hi Graeme,
    I dont understand what you mean by redirection to file? some of my code below.

  • Problem with threads and camera.

    Hi everybody!
    I've a problem with taking snapshot.
    I would like to display a loading screen after it take snapshot ( sometimes i
    have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
    I was trying to use threads but i didn't succeed.
    I made this code:
    display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while((!performing.isShown()) && (backgroundCamera.isShown())){
                        Thread.yield();
                    notifyAll();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        this.wait();                   
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();This code is sometimes showing performing screen but sometimes no.
    I don't know why. In my opinion performing.isShown() method isn't working correctly.
    Does anyone have some idea how to use threads here?

    Hi,
    I've finally managed to work this fine.
    The code:
           Object o = new Object();
           display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while(!performing.isShown()){
                        Thread.yield();
                   synchronized(o) {
                      o.notify();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        synchronized(o) {
                           o.wait(1);
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();

  • Problem with threads hanging

    We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
    We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
    A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).

    String.java line 1446 for this jdk allocates a new String object, and all the other threads in this state also are creating new objects or arrays, etc.
    We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

    Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

    Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there.  Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this. 
    We're using the following memory options:
    -ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
    -verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
    Thanks!

  • Problem with threads and ProgressMonitor

    Dear Friends:
    I have a little problem with a thread and a ProgressMonitor. I have a long time process that runs in a thread (the thread is in an separate class). The thread has a ProgressMonitor that works fine and shows the tasks progress.
    But I need deactivate the main class(the main class is the user interface) until the thread ends.
    I use something like this:
    LongTask myTask=new LongTask();
    myTask.start();
    myTask.join();
    Now, the main class waits for the task to end, but the progress monitor don`t works fine: it shows only the dialog but not the progress bar.
    What's wrong?

    Is the dialog a modal dialog? This can block other UI updates.
    In general, you should make sure that it isn't modal, and that your workThread has a fairly low priority so that the UI can do its updating

  • Problem with threads and/or memory

    I'm developing an application where there are 3 threads. One of them sends a request to the other, and if the 2nd can't answer it, it sends it to the 3rd (similar to CPU -> CACHE -> MEMORY). When i run the program with 1000-10.000 requests, no problem occurs. When i run it with 300.000-1.000.000 requests, it sometimes hangs. Is this a problem with the garbage collector, or should it be related to the threads mecanism.
    (note: eache thread is in execution using a finite state machine)

    i had been running the program inside Netbeans.
    Running the jar using the command line outside
    Netbeans i have no more problems... Does Netbeans use
    it's own JVM?Depends how you set it up, but look under the options. There are settings for the compiler and jvm that it uses.

  • Installation problem with NW'04 SR1: database connection failed

    Hi all,
    while installing NW '04 SR1 on Windows Server 2003 SP1 and MS SQL Server 2000 SP4 I ran into an error related to the database connection. While performing the step "Load Java Database content" SAPinst crashes with the message
    com.sap.sql.log.OpenSQLException: Could not load class com.ddtek.jdbc.sqlserver.SQLServerDriver.
    The connection to the SLQ Server with e.g. the Query Analyzer is OK. I had a problem with this installation setup before (have a look at the corresponding <a href="https://forums.sdn.sap.com/thread.jspa?threadID=338638&tstart=0">thread</a> ), the JDBC drivers where missing on the installation master but after copying them in the right direction the installation went on with no problem up to this point...
    Has anybody an idea what could have happened here? Is this maybe a problem connected to the one I recently had
    Below I attached the sapinst.log and jload.log with more detailed messages.

  • Problem with item and/or data during page-processing-PS/SQL

    Greetings!
    On my page I have a custom report (from 2 tables) and a small form-field, that adds and edits data in the report. After generating the form with the wizard I added an extra item, to store the id from one of the tables from the report data.
    Now, on submit a calculation should take place, that updates data according user input with a procedure in Page-Prosseses:
    declare a number;
    begin
    case :PLATZ
    when 1 then a:=100;
    when 2 then a:= 50;
    else a:=25;
    end case;
    update TBL_MITGLIEDER set TURNIERPUNKTE = TURNIERPUNKTE + a
    where ID_MITGL = :P14_ID_MITGL;
    end;
    :PLATZ is user selected (1,2,3), :P14_ID_MITGL stores the reference to TBL_MITGLIEDER (and shows the change, when I select another record)
    As I understand, that process should also run, when I submit a chance, but nothing happens then.
    But when I try to save a new record (which worked without any problems before adding that process), I get this error message:
    ORA-06550: line 1, column 64: PL/SQL: ORA-00957: duplicate column name ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
         Error      Unable to process row of table TBL_TURNIERSIEGER.
    Then, when I go back into the app-builder and try to run the page again, I get this message:
    ORA-01403: no data found
         Error      Unable to fetch row.
    I am not sure, if you guys have all the information you need, to know whats going on. Maybe this has to do with session-id and the whay, items are updated. I hope you can help me.
    Thanks, best regards,
    tobi

    First can you please post all log file errors
    >> I can't really give you a solution or specific recommendation since I did not saw this error yet myself, but on your own risk you can try:
    1. You may try to just register 'dts.dll' using regsvr32.exe, but this error may indicate a bigger problem with setup.
    If you are running SQL Server 64bit then try running this at the command prompt: %windir%\syswow64\regsvr32 "%ProgramFiles(x86)%\Microsoft SQL Server\90\dts\binn\dts.dll"
    2. You can try reinstall from start (In this case you have to make sure that you un-install all)
