Java attempts to mutate in notifications

I have two tables and a module they all look at

Basic – they should all update the module and update from it Is there a simple way to do it without binding the framework

I do (but I keep trying to mutate in notifications) –

Update about my textfield

myTextField.getDocument().addDocumentListener(new TFDocumentListener() {
            protected void userChangedTF() {
                Float value = myTextField.getValue();
                if (value != null) {
                    myObj.setMyAttribute(value);
                }
            }
        });

Still in UI – register changes

myObj.addMyAttributeChangedListener(new Valuechangelistener<Float>() {
            @Override public void valueChanged(Float value) {
                if (!myTextField.isFocusOwner()) {
                    myTextField.setValueIn(value);
                }
            }
        });

In the module – when setmyattribute occurs – it calls this function

private void notifyIntervalChanged(float newValue) {
    for (Valuechangelistener valuechangelistener : intervalChangedListenersList) {
        valuechangelistener.valueChanged(newValue);
    }
}

I announced

public interface Valuechangelistener<T> {
     void valueChanged(T Value)
}

Solution

If you need to change the contents of the same JTextComponent in the listener, in swingutilities Changes in invoker() (for example, settext())
