I use version 1.2 of niftygui I Had No Problem with my older version of jme3
I use the drag and drop nifty gui
Bump. Same problem here, however with creating buttons:
Neither the <control …/> tag nor the <button …/> tags seem to work 
Uhm, that looks odd. Seems like the control definition is missing. Is the “nifty-default-controls” project available in your classpath and did you include it:
<useControls filename=“nifty-default-controls.xml” /> ?
hi @void256,
(linked thread: http://hub.jmonkeyengine.org/forum/topic/nifty-gui-editor/page/7/#post-299241)
I fixed it!
just found that the style id is dynamic, cool!
thx for creating nifty gui!
