Part of path returned from Directories Only JFileChooser is sometimes duplicated

Question

In my application, I want the user to be able to select a directory to store stuff in. I have a text field that I'm using to display the directory they've chosen. If they just click on a directory (don't browse it), everything is fine. However, if they double click on the directory and look inside it, the directory name is duplicated.

Ex. They're in the home directory, single click the folder Desktop...path returned is ~/Desktop. On the other hand, if they're in the home directory, double click the folder Desktop, and now are in the Desktop folder, path returned is ~/Desktop/Destkop.

Here's what I'm doing:

JFileChooser chooser = new JFileChooser();
chooser.setMultiSelectionEnabled(false);
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
int returnVal = chooser.showOpenDialog(this);

if (returnVal == JFileChooser.APPROVE_OPTION) {
    File f = chooser.getSelectedFile();
    loadField.setText(f.getPath());
}

I've also tried to do something like chooser.getCurrentDirectory() but that doesn't really work either.

Edit: Using Mac OS X, Java 1.6

Answer 1

Seems to work for me.

import javax.swing.JFileChooser;

public class FChoose {
    public static void main(String[] args) {
        java.awt.EventQueue.invokeLater(new Runnable() { public void run() {
            JFileChooser chooser = new JFileChooser();
            chooser.setMultiSelectionEnabled(false);
            chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
            int returnVal = chooser.showOpenDialog(null);

            if (returnVal == JFileChooser.APPROVE_OPTION) {
                java.io.File f = chooser.getSelectedFile();
                System.err.println(f.getPath());
            }
        }});
    }
}

If there's a specific bug in a Mac OS X implementation of Java, you may want to, say, check if the file exists and if not de-dupe the last to elements of the path.

Answer 2

The problem occurs when you use chooser.showDialog or chooser.showSaveDialog instead of chooser.showOpenDialog. On XP chooser.showDialog returns the correct path under the example given by the OP, but on Mac OS 10.5.7 (and probably earlier versions as well) you'll get ~/Desktop/Desktop . (In my case I need to use showSaveDialog because I want users to have the option to create a new folder, so it looks like I'll have to de-dupe the path manually. It sure looks like this is a bug in the Apple Java implementation.)
