NiftyGUI Design module is not working when Text elements are present inside XML

Inside the “Design” section of Jmonkey plateform, when editing NiftyGUI xml, the “preview” of nifty xml seems not to work when a “text” element is present inside the xml.

If i remember this part was working just before taking the update of Jmonkey platform.

The xml itself is valid :at least when testing the same xml in debug, the text element is displayed propely as well as the whole gui.

Could someone confirm this?
