Clear jTextfield when using DocumentListener

Hi

I am using a barcode scanner to enter text into a jTextfield, then using a DocumentListener (insertUpdate method) to detect inserted text in this field. When this is triggered it selectes the current item in a jComboBox, based on the text data in the jTextField, which in turn adds the current selected item onto a table.

The above functionality works, but the issue I have is that, although the text field regains focus, I cannot get the text field to be cleared of text, so that when another barcode is read it is not appended to the end of the current data.

Can you advise, with a code snippet, how I can clear the textfield ot its data after an event is registered and the action taken in the combobox and table. I have tried adding a foo.setSelectedText("") on the text field but this stops the above functionality from working.

Should I use an additonal listener on the text field? But how would I stop this from triggering before the DocumtnListener has actioned based on the current text in the field.

Code for the DocumentListener...

        main.tillPanel.txtBarcode.getDocument().addDocumentListener(new DocumentListener() {

            public void removeUpdate(DocumentEvent e) {
            }
            public void changedUpdate(DocumentEvent e) {
            }

            public void insertUpdate(DocumentEvent e) {

                String selectedBarcodeItem = main.tillPanel.txtBarcode.getText();
                for (int d = 0; d < roundStockObj.length; d++) {
                    if (roundStockObj[d].getBarcode().equals(selectedBarcodeItem)) {
                           
                   main.tillPanel.cmbTillProdSelect.setSelectedItem(roundStockObj[d].getDescription());
                        break;
                    }
                }
         }
});

Thanks in advance
