Object moving vs. Duplication

I have a fairly involved file browser object which I want to display in two tabs. However, performance-wise, I'm not sure if its better to move it around to the visible tab, or to take on the overhead of duplicating the object on two tabs.
Anyone have any suggestions on how to proceed?
thanks,
adam

I'd say try both and profile the results. The easier and quicker (performance-wise) way will be two distinct components.
You will have to see how big the extra memory overhead really is and if its worth it.

    I don't know what else to say other than I have had Firefox for a while and an update came up and so I updated and Firefox has not worked right since then. I open a tab and it comes back Object Move (here) or Object moved temporary or some such crap.

  • Web service 302 object moved error

    Hi All,
    Last week, IT changed the configuration on our Cisco content
    switch to redirect every page request to https. Everything seems to
    be working properly except for our Web services, which I can't seem
    to consume at all. Here's the error we keep getting:
    Could not perform web service invocation "myFunction"
    because AxisFault faultCode: {
    http://xml.apache.org/axis/}HTTP
    faultSubcode: faultString: (302)Object moved faultActor: faultNode:
    faultDetail: {}string: return code: 302
    Does anyone have any experience serving Web services over a
    content switch that forces a redirect over https? I even get this
    message when trying to consume over https. Our Web servers think
    they're not secured at all, maybe this is the problem? I just
    haven't worked with Web services very much.
    Thanks in advance!
    Cheers,
    -m

    ColdFusion sometimes has some problems connecting to
    webservices using HTTPS.
    Try Daverms's suggestion first. Recreating or refreshing the
    webservice in the CFADMIN might fix your problem. Otherwise, if
    that doesn't work I suggest:
    Try saving the WSDL to a local location and running the
    webservice off the local WSDL. The WSDL should have the location of
    the actual webservice in it (I think the tag is <ServicePort>
    or something like that), so it doesn't really matter where the WSDL
    resides.

  • Why do I keep getting this message when I try to go back to previous page? "object moved to here"

    This is so annoying. I use ancestry.com a lot and after I look at a census or a person on ancestry.com, I try to use the back arrow to go back to the page I started on and the screen goes white and it says "object moved to here." The "here" is a link, but it doesn't work to get me back to the page I want. I have to use the back arrow several times and sometimes it works and sometimes it doesn't, then I have to start ancestry all over again. This is so annoying!

    This is likely an issue with the site and you'll have to contact them and ask them to fix it. But a link to a public page where this happens and lets us reproduce the problem might be helpful.

  • Help! Javascript not working when object moved from one page to another!

    Hello all:
    I am new to Adobe Livecycle Designer (version 8.0). I have created a 3 page interactive pdf form with numerous objects (text fields, radio buttons, drop-down boxes, etc.), that our business wants to begin using soon.
    I am having difficulty with some of my Javascript not working with a few of my objects on page 2 of the form. Specifically, there is a drop-down box for "Country" on page 2 of my form. When the user selects, for example, "United States" from the list, I have Javascript that is supposed to change the "Currency" drop-down box rawValue to "US Dollars" accordingly (upon the change event).
    I think my Javascript syntax is proper, but I am not certain. Here is my simple Javascript associated with the "Country" drop-down box (Note: rawValue 80 = "United States" and rawValue 105 = "US Dollars"):
    form1.Page1.cmbContactInfoCountry::change: - (JavaScript, client) -
    if (this.rawValue == 80) {     
         cmbCurrency.rawValue = 105;
    This seems pretty straight forward and it WORKS when my "Country" drop-down box is moved to page 1 of the form, but it WILL NOT WORK when I move the "Country" drop-down box back to page 2 of the form (which is where it belongs).
    Does anyone have any suggestions or solutions? I have spent probably 6-8 hours racking my brain trying to figure out why it works when on one page, but it does not work when move to a different page. I am guessing that I may have corrupted something OR that I am not fully addressing the proper name of the object?
    Please help!
    Frustrated and helpless near Chicago!
    Taylor T

    Hi Jono:
    Thank you for your quick reply.I was able to obtain the full name of the cmbCurrency object using the method you taught me. That is brilliant! Great short-cut tool.
    Unfortunately, I am still having issues with getting Javasript for the cmbCountry object to work with the cmbCurrency object. I haved pasted my new Javascript below.
    JavaScript for cmbCountry object:
    //UNITED STATES
    if (this.rawValue == 1) {
              xfa.resolveNode("form1.#subform[1].cmbCurrency").rawValue = 1;
    else
    //CANADA
    if (this.rawValue == 2) {
              xfa.resolveNode("form1.#subform[1].cmbCurrency").rawValue = 2;
    I have checked the "Specify Item Values" checkbox of the cmbCurrency drop-down object and Value 1 = "US Dollars" and Value 2 = "Canadian Dollars".
    When I select "Canada" from the cmbCountry drop-down object, the rawValue of the cmbCurrency drop-down object is changed to "US Dollars" (when it is clearly defined as "Canadian Dollars"). When I select "United States" from the cmbCountry drop-down object, the rawValue of the cmbCurrency drop-down object stays blank for uknown reasons. Very strange.
    Since I am not able to further explain in detail on what I am experiencing, I have posted a link to my file below (I just signed up for an account at ShareFile). I would forever be indebted to you if you can help me figure this out!

    I am developing a java application. I need to provide some scripting support (using Jython or Rhino) to my application so that the user can better use my application. Now the problem is I just want a select few public objects to be accesible via scripts and not all public objects I have written internally. I read somewhere that class name and code obfuscation could be a option but not a full proof solution. Can anyone suggest how a full proof solution can be achieved? Would running the script interpreter in seperate JVM help (and propogate the calls to the original JVM) ? Would a custom class loader help? Please suggest.

    The plan is:
    Let say I have 2 public objects A & B and I want the user to only use A via their scripts.
    In JVM1: I use both A & B
    In JVM2: I write a psuedo A and not B. For all the methods of A, I propogate the calls to JVM1 (I think this is achievable but not sure how)
    The script interpreter runs on JVM2.
    Now if the user tries to access A then the call would go to JVM1 but if he tries to access B then there is no B available in JVM2 so the user cant access B.
    I know this method could be heavy as each call would have to go from JVM1 to JVM2.
    By sepeate JVMs I mean seperate instance of java.

    RMI has a way for multiple JVMs to communicate programmatically; you could also use sockets on the loopback network device (localhost). These techniques are how mature Java products constrain their number of running instances to a finite number (usually 1), they terminate any starting JVM early in the initialization procedures of the main method if the "already-running test" indicates one is running.
    If you use the networking method, you could basically read from a ServerSocket on the "executing" JVM, while the "scripting" JVM writes to a Socket. Then use reflection in the executing (server) side to determine if the method or object being referenced is one you want to expose. If not, do something -- like write back to the client that the method invocation was invalid. Reflection will slow down your code a lot though, so I don't recommend it for apps that already take up 50 megs or more of RAM ;)

    Ya, the seperate JVM approach seems complex and might not be fully achievable.
    Can someone give small code snippets on how the method level control be achieved using Java SecurityManager. Just a recap on what I am trying to achieve -
    A & B are two public objects defined internally by my app.
    I have to give the user of my app the ability to write some code. But only B
    is to be exposed to client and not A.
    Let say I have this code -
    Object A = Interpreter.InitializeEngine(..);
    A.executeFromUser(stdin);
    The user mostly uses some scripting language, say Python and the Interpreter
    is Jython. Now my Interpreter is capable of understanding calls to Java
    objects from Python. If the user tries to access B via the scripts then it
    should be allowed to do so but access to A should not be allowed via the
    scripting language.

    What you probably want is to give the user access to an interface - not a class - that only exposes the methods that you want to expose.
    This is the way all RMI APIs are exposed to client programs.

    Just one more comment. You haven't said very much about the runtime model of the scripting environment vs your java environment. How many processes do you expect to have running to make the system work? Are you expecting your java code to wind up in a jar file and get loaded by the Python process? Or are you planning on the java code executing in a separate process? If the latter, then RMI is probably your best bet.

    I haven't finalized on the runtime model yet as the scripting security issue is still not resolved. But I am sure that the java app code would init and run the scripting code and not the other way round. The app is pretty huge with heavy UI. Ya, the java code would be wrapped in jars (but mostly not in a single jar as I dont want the jar to be too hefty).
    Can someone comment on the use of SecurityManager in this case. My initial investigation shows that the objective on implementing method level security can't be implemented by this.

    My initial reply suggested writing a facade in java or by subclass PyObject. I highly recommend this path for ease of development, use, and runtime performance.
    Given that you don't understand the basics of java security, I will recommend this again.

    I have started investigating on facade in java and subclassing PyObject. But I am not sure how these would resolve the primary issue. Even if I use these and if the script writer knows that there is a public class, say XYZ in my app then he can always access that class directly skipping my subclassed PyObject or the Java facade. Or am I missing something here?

    from com.foo import Player
    p = Player()
    p.setGold(Integer.MAX_VALUE)But of course the new Player object would not be part of the game. Now if you have some kind of static/singleton game state, then the malicious user could insert the Player into the game model...
    The real trick lies in understanding how to setup the jython interpreter. If your interpreter classloader can only load facade classes (and system classes) then the client script could not load other classes. There is also a hook for the import keyword so you could disallow importing java classes. Each interpretor instance has the ability to setup the locals and globals for the session so you can insert live game objects.
    I am only familiar with jythons internals, so this may or may not be applicable to rhino.

  • How to code a "tween" object moving like in Flash?

    As you may know in Flash the user can easily implement movements (including rotations) of objects by so called "tweens".
    The developer defines e.g. the start and end position of a picture and how many rotations should
    be applied and Flash generates the moving itself automatically. Thats nifty.
    How can I implement this in Flex?

  • Lock object moved to qa system standard fm(enque,deque) didnt move.

    Hi,
    I created one lock object named as ez_lockworkid in developement system and i stored that in YMM package . Two standard function modules(enque,deque) was created successfully . It was in $enq package . I moved the lock object to quality .
    The problem is only lock object is moved but the two standard function modules didnt move to the lockobject.  How can i solve the issue.

    Hello Karthick,
    The ENQUEUE* & DEQUEUE* FMs are not transported via the transport request(TR). I you wont get reference of these FMs in the object list of your TR either.
    When your TR is imported in your QAS the objects included in the TR will get activated. During the activation of your lock object, these FMs are "automatically" generated by SAP & saved in the the package $ENQ!
    Check the TR log & verify if the Lock object has been activated correctly in the QAS.
    Read the documentation of "[Lock Objects|http://help.sap.com/saphelp_nw2004s/helpdata/en/cf/21eebf446011d189700000e8322d00/content.htm]" for further details.

  • Bad effect when draw object moving fast

    Hi, i have a shooter game where a gun can shoot a bullet.
    This bullet run fast so i move it whit X+=dx (dx is distance in pixel)
    When the bullet run too fast i ahve a bad effect, ot smootly.
    How i can resolve?

    delay =30;
    Timer timer=new Timer(delay, new ActionListener(){
              public void actionPerformed(ActionEvent e){
                        processBulletPosition();
                        timer.setDelay(delay-delayed);
    public void processBulletPosition(){
             bullet.process(new 2DVector(10,0)); //2DVector is simple object contain dx and dy increment.
             repaint();
    //im use JPanel to paint, not canvas
    protected void paintComponent(Graphics g) {
              super.paintComponent(g);
              Graphics2D g2=(Graphics2D)g;

                    bullet.draw(g2);
                    delayed=(System.nanoTime()-nanoTime)*1E-6; //make delayed in millisec

              int dx=vect.dx;
              int dy=vect.dy;
              x+=dx;
              y+=dy;
    }Animation is very smooty, but when a bullet or an other object run too fast and dx increment is too many pixel the effect is very bad, and not smooty.
    I think i have same fps becouse i decrement delay time of a delayed time...
    Can you help me?

    One problem is that I'm not sure how accurate Timer is.
    A standard approach in this sort of animation is to measure the time since the last redraw and move each component based on the time difference, rather than trying to keep the redraws an exact time apart and moving the components fixed distances.
    The distance/time approach reduces the effect of pauses in your rendering code caused by outside influences such as the garbage collector and other game logic such as spawning controllers etc. It won't eliminate pauses but it makes them much less noticable.
