How to use Category Selector as Single Selector?

Answer

The Category Selector is multiple per default. It is not possible to use a single category selector. But instead the category selector a normal choiceList Initializer could be used like:

  - aSingleCategory (weakreference, choicelist[nodes='/sites/systemsite/categories//*;jnt:category;',sort]) internationalized indexed=no

The advantage: In the path of the categories, could be a specific subtree specified. So not all categories are available for the selection.
