BasicUI: Warnings in Log

Hi,
everything actually works however log shows the following warnings when accessing BasicUI which I would like to get solved.
I am not sure which part of my concat string causes it and what I could change to not have warnings.
Any hint is appreciated.

ui looks good:

Same here withe the date-example from the demo:

08:58:43.669 [WARN ] [ternal.render.AbstractWidgetRenderer] - Cannot escape path '2016-04-10T08:57:55.299+0200' in URL. Returning unmodified path.

Interesting setup @shorty707, you UI looks nearly like mine - how did you make the 3 values in the group-item like “Wohnzimmer”. Could you pleas give me an example for the item/sitemap to put out?
