Question. How to setup RSyntaxTextArea with Netbeans UI designer

[makiam]

Hello.
I try to setup RSTA using Netbeans UI designer and I see an issue with it.
Here the steps to reproduce
I create new form and add RTextScrollPane on it
Then I add RSyntaxTextArea into RTextScrollPane
Now I see next code...
Both components created with default no-args constructors
Then RTextScroll pane adds RSTA via setViewportView(ююю)
Once I run form I see TextEditor but I see no editor Gutter

Is there a way to properly setup this layout?
