Hi,

I have a JComboBox event handler which reads a file corresponding to the
selection, using BufferedReader, then populates a JTextArea with the file
contents. This is the code I'm concerned about:

void showManifestFile(String filename) throws IOException {

// Populate the list box with the contents of the specified file

  String inputLine;

  try {

    inStream = new BufferedReader(new FileReader(filename));

  } catch (FileNotFoundException e) {

    inStream.close();

  showMessageBox("Unable to open " + filename + " on local machine.", true);

}

while (true) {

  inputLine = inStream.readLine();

  if (inputLine == null) break;

  if (inputLine.length() == 0) continue;

  jManifestInfoTextArea.append(inputLine + "\n");

}

inStream.close();

} // showManifestFile



The problem is that the event handler is being called twice, so the text
ends up in the text area twice. I read somewhere that it may be because the
event handler doesn't register completion until the input stream has closed,
so that the next time it checks for events, it hasn't been satisfied yet and
gets fired again.



Is this true? I have other combo boxes with very similar code, except that a
BufferedReader is not involved, and the action performed events only fire
once, as expected.



Any suggestions please?
