The component doesn’t show for me. Creating it as a variable and adding that to the layout or simply calling add(new EnhancedRichTextEditor doesn’t result in anything other than it taking up a small amount of space; a button placed below it gets moved slightly down.
In other words, Vaadin recognises it as a component (commands such as setValue() and getValue() work just fine), but it doesn’t display anything useful. It’s much the same as with the JuicyAceEditor, unfortunately.
