PropertyChangeListener does not always fire

Hi, I have an edit screen that uses a PropertyChangeListener to listen for changes to a particular attribute and then format the screen accordingly. But the listener only works about 70% of the time. Sometimes when invoking the editor, changing the lookup value does nothing.

I am creating the listener in the postInit method. Is this proper?

Today, I upgraded from 6.8 to 6.9 snapshot. I’m not sure if this is relevant but I don’t recall having this problem in the past.

Groovy code:

protected void postInit() {
    getItem().addPropertyChangeListener(new Instance.PropertyChangeListener() {
        void propertyChanged(Instance.PropertyChangeEvent e) {
            String property = e.getProperty()
            showNotification("Property (${property}) changed with value: ${e.getValue()}")  //Does not always show
            if(property == "someAttribute") {
                //format screen

Unfortunately, we cannot reproduce the problem. We will be able to help you if you send us a small sample project along with reproduction scenario that demonstrates the issue.

I am now also unable to reproduce it. I promise, I didn’t change any code. Strange… So sorry to waste your time. Thank you.
