Editable JCombobox - bug in 10.1.3

Hi I have a JComboBox bound to a ADF view object
JComboBox cbo = new JComboBox();
cbo.setEditable(true);
cbo.setModel((ComboBoxModel)panelBinding.bindUIControl("PortfolioView1", cbo));
When I type in additional data in the combobox (its editable) and hit a "Search" button I was expected to get the newly entered value in the
cbo.getSelectedItem() method
This does not work though - I get the PortefolieViewRow object instead. When I instead use
((JUMultiAttrListEditor)cbo.getEditor()).getItem())
I get null.
Creating a non ADF bound combobox work fine - the getSelectedItem() return either my selection or the newly typed in value
It clearly a bug - but is anyone aware of a workaround?

Hi Frank
I'm using editable comboboxes to lookup values based on a VO list. I'm aware that the entered values are not inserted in the list - this is expected.
So I create a VO, drag it as a combobox to a Swing panel. The combobox is made editable so that I can type in info in the combobox.
I then have a JButton that, when pressed get the value of the combobox and performs a search in the database. I use the combobox.getSelectedItem() method to get its value - this step does not work though.
The values in the combobox is either a value the user has written (because the field is editable) or a value from the VO.
The Combobox is not directly bound the the search button only as a lookup facility so that the user either can type in some text or select it from a list
hope this clarified my context
:-) johnny

  • Editable JComboBox in JTable

    There is a bug in Jdk1.5 (bug#4684090) - When TAB out from Editable Jcombobox in JTable, the focus is moved to outside JTable instead of next cell.
    What is the best workaround for thsi bug.
    Thanks,

    I was using java 1.5.0_06 in my application and I had this problem
    When I upgraded to java 1.6.0_01, I no longer had this issue.
    This seems to be a bug in 1.5 version of Java that has been fixed in 1.6

  • Update the testfield when setSelectedItem() for editable JComboBox

    Hi,
    I am having problem with setSelectedItem() and setSelectedIndex() methods of editable JComboBox.
    I extended JComboBox with default dataModel. When I enter some string in the textfield of the combobox, I call insertItemAt() method to dynamically grow the list. The application requires to clear the textfield everytime I enter something and press "return" key. To make it work, I insert an empty string to the list at the very beginning and call the setSelectedItem("") method in the actionPerformed().
    Now the problem is that I know the setSelectedItem("") is called since the getActionCommand() returns "comboBoxChanged" everytime I enter something in the textfield, but the testfield is not cleared. And if I select one item from the list and press "enter" key, the textfield is cleared. To make things more interesting, after I enter the first string and press "enter", the textfield really get cleared, but not for all other later input. Is this a bug? Can anyone please help me? Thanks a lot. Below is my code snippet.
    public class MyComboBox extends JComboBox implements ActionListener
    public GsISCommComboBox()
    jbInit();
    private void jbInit() throws Exception
    this.setEditable(true);
    this.addActionListener(this);
    insertItemAt("",0);
    public void actionPerformed(ActionEvent e)
    String str=null;
    String strrr=e.getActionCommand();
    System.out.println("getActionCommand: "+strrr);
    if(strrr.equalsIgnoreCase("comboBoxChanged"))
    str=(String)this.getSelectedItem();
    return;
    else
    str=strrr;
    // other stuff to process the string and do things
    setSelectedItem("");
    repaint();
    hidePopup();
    insertItemAt(str,0);

    Try inserting your string first and then, try clearing the combobox's textfield.
    insertItemAt(str,0);
    setSelectedItem("");
    hidePopup();
    repaint();
    Since you add the "" string at the begining, it will have the index 0. Perhaps, you want to insert your string this way:
    // insert string at the end
    insertItemAt(str, this.getItemCount());
    //Then use the
    setSelectedIndex(0);
    But you need to remember that if you add an item at the begining, index 0 may not be your '' '' string after that.
    I hope that it helps.

  • How can I use a FocusEvent to distinguish among editable JComboBoxes?

    Hi,
    I have a Frame with multiple editable JComboBoxes, but I am at a loss as to how to sort them out in the focusGained() method.
    It is easy when they are not editable, because the FocusEvent getSource() Method returns the box that fired the event. That lets me read an instance variable that is set differently for each box.
    But with editable boxes, the FocusEvent is not fired by the box. It is fired by a Component object returned by getEditor().getEditorComponent(). So far I cannot find a way to query that object to find the box it it tied to. (I hope this isn't going to be painfully embarassing.).
    Anyway, the code below produces a frame with four vertical components: a JTextField (textField), a NON-Editable JComboBox (comboBox1) and two Editable JComboBoxes (comboBox2 & comboBox3).
    This is the command screen produced by :
    - Running the class
    - Then tabbing through all the components to return to the text field.
    I am not sure why, but it gives the last component added the foucus on startup.Focus Gained - Begin: *****
       This is the comboBox that Is Not Editable
    Focus Gained - End: *******
    Focus Gained - Begin: *****
       This Is The TextField
    Focus Gained - End: *******
    Focus Gained - Begin: *****
       Class: class javax.swing.plaf.metal.MetalComboBoxEditor$1
       Name: javax.swing.plaf.metal.MetalComboBoxEditor$1
    Focus Gained - End: *******
    Focus Gained - Begin: *****
       Class: class javax.swing.plaf.metal.MetalComboBoxEditor$1
       Name: javax.swing.plaf.metal.MetalComboBoxEditor$1
    Focus Gained - End: *******
    Focus Gained - Begin: *****
       This is the comboBox that Is Not Editable
    Focus Gained - End: *******
    Focus Gained - Begin: *****
       This Is The TextField
    Focus Gained - End: *******As you can see, the FocusEvent source for both editable boxes is a MetalComboBoxEditor. Both have identical names.
    Can anyone help me get from there back to the actual combo box so I can read the instance variable to see which one fired the event?

  • Editable JCombobox cell editor length limit

    Hi All,

    A JComboBox uses a JTextField as it's cell editor. You should read up on how you would do this for a normal JTextField by using a custom Document:
    http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html

    And make a provision to delete wrong entries, or you'll end up with all the typos stored separately.

    editable JComboBox in a JTable
    Oct 21, 2006 1:32 PM
    Click to email this message
    Hello!
    Yesterday I posted a problem, solved it and there's another one, referring the same theme.
    So it's about a editable JComboBox with autocomplete function. The combo is a JTables cellEditors component. So it's in a table. So when the user presses the enter key to select an item from the JComboBox drop down menu, I can't get which item is it, not even which index has the item in the list. If for exemple the JComboBox isn't in a table but is added on a JPanel, it works fine. So I want to get the selectedItem in the actionPerformed method implemented in the combo box. I always get null instead of the item.
    Oh... if user picks up some item in the JComboBox-s list with the mouse, it's working fine but I want that it could be picked up with the enter key.
    Any solutions appreciated!
    Thanks, Tilen

    I suggest that you distill your current code into a simple class which has the following attributes:
    1. It can be copied and pasted and will compile straight out.
    2. It has a main method which brings up a simple example frame.
    3. It's no more than 50 lines long.
    4. It demonstrates accurately what you've currently got working.
    Without that it's hard to know exactly what you're currently doing, and requires a significant investment of time for someone who hasn't already solved this problem before to attempt to help. I'm not saying that you won't get help if you don't post a simple demo class, but it will significantly improve your chances.

    Okay ... I'll write the code in short format:
    class acJComboBox extends JComboBox {
      public acJComboBox() {
        this.setEditable(true);
        this.setSelectedItem("");
        this.getEditor().getEditorComponent().addKeyListener(new KeyAdapter() { public void keyReleased(KeyEvent e) {
         // ... code code code
         // that's tricky ... the method getSelectedItem() always returns null - remember; the acJComboBox is in a JTable!
         if (e.getKeyCode() == 10 && new String((String)getEditor().getItem()).length() != 0) { getEditor().setItem(getSelectedItem()); }
    }And something more ... adding the acJComboBox into the JTable:
    TableColumn column = someTable.getColumn(0);
    column.setCellEditor(new DefaultCellEditor(new acJComboBox());
    So if the user presses the enter key to pick up an item in the combo box drop down menu, it should set the editors item to the selected item from the drop down menu (
    getEditor().setItem(getSelectedItem());
    When the acJComboBox is on a usual JPanel, it does fine, but if it's in the JTable, it doesn't (getSelectedItem() always returns null).
    Hope I described the problem well now ;).

    Okay look ... I couldn't write a shorter code just for an example. I thought that my problem could be understoodable just in mind. However ... type in the first combo box the letter "i" and then select some item from the list with pressing the enter key. Do the same in the 2nd combo box who's in the JTable ... the user just can't select that way if the same combo is in the JTable. Why? Thanks alot for future help!

  • How to create full editable JComboBox  ?

    I need to create full editable comboBox -- i want to do it by extends the class JComboBox - but i dont realy know how to collect the chars that the user will be insert and show then on the control.
    Does someone know where can i find some example of editable JComboBox ?
    Thanks.

    JComboBox can already be made editable, so you need to clarify what exactly you mean by "full editable"

  • Can JOptionPane produce an editable JComboBox?

    Can I use JOptionPane for an input dialog component with a data input area represented by an editable JComboBox ?
    For example :
    JOptionPane.showInputDialog( parent,
    � How Much?�,
    �This is the title�,
    JOptionPane.QUESTION_MESSAGE,
    null,
    new Object[]
    { � �, �un peu�,�beaucoup�,�passionnement�},
    �passionnement�);
    This one statement produces the input dialog I want, except that it does not allow an input such as �pas du tout� which is not in the list of selections.
    Does any one knows if somehow I could get to this JComboxBox and make it editable? (still using JOptionPane of course)?
    Thank you to any one who can answer me.

    Hi,
    You could use the JOptionPane.showMessageDialog() in the following way:
    JComboBox comboBox = //Make your own JComboBox here
    Object[] message = new Object[] {
    "Make your choice:",
    comboBox
    JOptionPane.showMessageDialog(parent, message);
    In this way you are able to add every Component to your message dialog you want to.
    Hope that helps, Mathias

  • Editable JComboBox inside JTable clipping issues

    Here is an example of what I am talking about
    http://img95.imageshack.us/img95/9514/clipping4fw.png
    As you can see, the bottom of the editable JComboBox is being clipped. Is there any way to remove what looks like the invisible border there?
    Thanks
    Daniel

    I am not sure if I understand your question exactly. Your table's row height is not high enough so you may need to add a line of code like:
            table.setRowHeight(table.getRowHeight() + 4);to solve your problem.

  • JTable with editable JComboBoxes

    For some reason once I added editable JComboBoxes to a JTable I can no longer tab among the fields in the table. If I just select a cell, I can tab to the other cells in that row, and then to proceeding rows as I reach the end of each. However if I double click the cell and enter data or select from the combobox. I no longer can tab to the next cell. At that point once I do hit tab, I am taken to the next table. Not the next cell in the row, or the next row in the current table.
    I have tried messing with a bunch of listeners, but I am not using the right listener on the right object? What listerner and object should the listener belong to? Table, model, cell editor, combobox, jpanel, jframe ? I hope this is not to vague.

    Well I am starting to think it's an implementation issue. Like I am not doing it how I should. I am basically doing
    JComboBox jcb = new JComboBox();
    jcb.setEditable(true);
    column.setCellEditor(new DefaultCellEditor(jcb));
    When I think I should be inheriting, and creating my own editor and/or renderer? Now my combobox vars are globally available in the class, so I can set and clear their contents. It does not matter that each row in the table has the same content in the combo boxes, that's basically what I want. User to be able to select an existing entry or make a new one.
    What I am trying to do is on tables have a drop down box that shows up when a user types a matching entry. If no entry matches, no popup box. If entry matches, box pops up and shows possible entries starting with what they are typing. Like code completion in IDE's like Netbeans. However I am doing this in a table. I thought a JComboBox would be a good widget to start with?
