Thanks Martin,
I am still learning so AbstractAjaxBehavior was my first choice. No reason...
I have changed it to AbstractDefaultAjaxBehavior and added the following code
to the respond method.
target.addComponent(feedback);
error(errorMessage);
However I still receiving the same WARNING message.
Layout
Page
- feedback
- form
- TextFields
- AbstractDefaultAjaxBehavior has been added here.
I must missing something very basic.
