How to use categories for coloring in TrackerCalendar
I am providing a complex calendar based on a tracker with a category field to control access rights and an additional textfield for coloring. I would like to use the category field for coloring to simplify entering new items, but I failed specifying categories in the colormap.
I tried several variants such as
TRACKERCALENDAR (... coloring="calCatField" colormap="41,#FFFF80|42,#44FF80|43,#AAAAAA" ...
Has somebody already succeeded using the correct notation or is there a limitation that categories are not supported for colormaps?
