Recently I reported a bug that in a Jedox list box you are able to deselect all elements in the box itself. This would have been very useful feature as you could use the result for dynamic pick list in subset (to add individual elements to a given subset by user or not).
BUT: Very unfortunately even though you are able to deselect all items to define "empty additional elements" in the list box the output of it e.g. named range of the list box will not be refreshed. It will keep the last selection until you select something else.
This makes it impossible to deselect additional items as you at least have to select 1 item. This is very confusing and inconsistent behavior. At the same time it is not visible for the front end user as he de-selected everything but it doesn't refresh.
