Wrong argument to the function - AutoComplete in JComboBox

I am using a JComboBox as a cell editor for one of my JTbale column.I want to implement autocomplete in my JComboBox. I used a jar file from this link here. When I run my program it is giving me this error:

at Exception in thread "AWT-EventQueue-0" java.lang.VerifyError: (class: org/jdesktop/swingx/autocomplete/Configurator, method: enableAutoCompletion signature: (Ljavax/swing/JComboBox;)V) Incompatible argument to functionquotationTable.DescriptionColumnEditor.populateComboBox(DescriptionColumnEditor.java:68)

I have imported the right jar; this I confirmed when I checked with this question here. My code for adding the functionality needed is:

 combo=new JComboBox(myList);
        Configurator.enableAutoCompletion(myComboBox); //this is the line generating the error.

How do we resolve this? I was suspecting this lineJComboBox comboBox = [...]; what does it do? It my be that I am creating my combobox the wrong way.

Solution

  • "I have imported the right jar; this I confirmed when I checked with this question here."

    No it doesn't. That question still unanswered because OP couldn't solve their problem (see the comments on that post). Besides as far as I know there is no class named Configurator in SwingX library which you are using to get the auto-complete decoration in your combo box. Even in this list (you've linked in your question) there is no such class:

    No org.jdesktop.swingx.autocomplete.Configurator class

    Now, the right way to provide auto-complete decoration is using AutoCompleteDecorator as follows:

     JComboBox comboBox = new JComboBox();
 AutoCompleteDecorator.decorate(comboBox);

    Note

    Also note the current version is 1.6.4 not 1.6.2
