I did, but there is nothing in the stack that points to the event being called twice. To make sure it's not the code withing the event, I commented all code out except for one line. It still keeps on repeating even with just one line of code within it.
public void jBtnImportAllFMEA_actionPerformed(ActionEvent e) {
jTextArea1.setText("test");
/*try {
jTextArea1.setText("");
quickExit: {
File f = new File(UploadFolder);
if (f.isDirectory()) {
String filenames[] = f.list();
fn = "";
jTextArea1.setWrapStyleWord(true);
for (int i = 0; i < filenames.length; i++) {
if (isLocked(msoFMEAUploadFolder + filenames[i])) {
fn = fn + "\nFile " + filenames[i] +
" is locked by another application.";
break quickExit;
}
}
for (int i = 0; i < filenames.length; i++) {
}
for (int i = 0; i < filenames.length; i++) {
fn = fn + "Attempting to import " + filenames[i];
if (filenames[i].endsWith(".xls")) {
loadFMEA(msoFMEAUploadFolder + filenames[i]);
fn = fn + " - done";
moveFile(UploadFolder + filenames[i], FFolder);
}
fn = fn + "\n";
}
}
}
jTextArea1.setText(fn);
}
catch (Exception ex) {
ex.printStackTrace();
} */
}
}
class msoImportFMEA_jBtnImportAllFMEA_actionAdapter
implements ActionListener {
private msoImportFMEA adaptee;
msoImportFMEA_jBtnImportAllFMEA_actionAdapter(msoImportFMEA adaptee) {
this.adaptee = adaptee;

adaptee.jBtnImportAllFMEA_actionPerformed(e);
