失去焦点时会触发insertUpdate

Question

I want to add a documentListener to a textarea in initcomponents() method.

This is my code:

txtAreaNot.getDocument().addDocumentListener(new DocumentListener() {

        public void changedUpdate(DocumentEvent e) {
            // text was changed
            textAreaSituation = "changed";
        }
        public void removeUpdate(DocumentEvent e) {
            // text was deleted
            textAreaSituation = "deleted";
        }
        public void insertUpdate(DocumentEvent e) {
            // text was inserted
            textAreaSituation = "inserted";
        }
    });

Here is what i dont understand; why insertupdate is fired everytime focus lost in textarea? I dont insert or change anything on it.

Answer 1

Sorry. My mistake. I totally forgot to change the value of textAreaSituation after focusLost event triggered. So it outputs the same value.
