[CLOSED] Itemselector questions
Hi guys,
Trying to use the itemselector, but I have 2 questions in my test app:
Why do I need to update the selecteditems to show the (still non selected) items in the 'available' box initially ?
Why can I loop throught the .selectedItems after choosing some --> Save, but can't I loop through the .items collection because it seems to be empty ?
Where do I go wrong ? :)
