    Question [HELP] Call JInternalFrame Trouble

    Dear All ,

    Please its support , I have problems to call JInternalFrame from JInternalFrame ,
    Here I am Using one JFrame and JDesktopPane as its ContentPane , then 2 JInternalFrame , following his pieces Coding :

    JInternalFrame 1
    / / Coding I created this in order to avoid double JInternalFrame which appear
    private static JInternalFrame1 myInstance;
        public static JInternalFrame1 getInstance() {
            if (myInstance == null) {
                 myInstance = new JInternalFrame1();
            }
        return myInstance;
    }
     
    JInternalFrame 2
    / / This comes from ActionPerformed Coding Button Add to call JInternalFrame 1
    private void btnTambahActionPerformed(java.awt.event.ActionEvent evt) {                                          
            // TODO add your handling code here:   
            JInternalFrame1 rd = JInternalFrame1.getInstance();
            if(rd.isVisible()){
               rd.toFront();
               rd.requestFocus();
            }else {          
            JFrame.JDesktopPane.add(rd); 
            rd.setVisible(true);  
            }     
        }

    Either Netbeans bugs or not , the first time Button Add be pressed , JInternalFrame1 appear without any problems , and if JInternalFrame1 closed (using dispose()) and then press again the Add Button appear the error :
    "Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: illegal component position"

    Please its support ,
    Thanks ,

    Please provide a short runnable example that demonstrates the problem.

    It's not clear what you're doing, but if you're deleting components in a container, then adding new components in place of the deleted ones, you may need to revalidate() the container.

    JInternalFrame2 is a Transaction Window & JInternalFrame1 is a Transaction Detail Window, When Add Button pressed in JInternalFrame2, JInternalFrame1 is showing. I use method getInstance() that i create to make sure only one JInternalFrame1 Window exist , piece of code attached above.

    But an error occurs, here is the error say in NetBeans : "Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: illegal component position"

    Sorry for my bad English, I try to explain it as easy as possible.

    Your English is fine. Don't sweat that.

    Netbeans is a fancy editor and graphical interface for building GUIs, if used that way. The description of an error as a Netbeans error isn't really helpful. It is much more helpful if errors are identified as either syntax (usually highlighted by the IDE before compiling), compiler (errors that occur when trying to compile), run time (errors that occur after the program has successfully compiled while running the program), or logic (errors that cause the program's results to be other than desired or expected.)

    The error you've posted is not clear, because I cannot tell what code it is complaining about. I've read a few posts by others who've had the same error, and it's usually because the Container.add() method (in one of its many forms) has been used incorrectly, either specifying a position that doesn't exist or being used to add a component to a container that is already full. Investigate that as a possible reason for your error.

    If you can't post a short, runnable example that demonstrates the problem, it would be helpful to see the entire error message, copied from exactly as it appears at your end and pasted into a post, with the specific line(s) of code mentioned by the error.
