\r\n \n In order to display the data properly the list needs to have a renderer defined (see the renderer element in the properties) \na String list will normally \"just work\" however a list of Hashtables will need keys to fit the names of the elements within the renderer.\n Normally such keys appear automatically in this editor if you defined the renderer properly.\n
\n \n Values for the keys can be boolean (true/false) which are useful for checkboxes, they can be Strings which can appear in \nlabels/buttons in the renderer or they can even be images which can also can be applied to labels etc.
\nA value can also be a navigation destination but that isn't represented visually other than by clicking the list element.\n
