Zdenek Sochor commented on TOMAHAWK-916:
----------------------------------------
Hi,
problem with example is in not initializing optionItems at all.
To fix example either initialize list in getter for optionItems OR invoke
getter for options prior to invoking getter for optionItems.
(List of optionItems is initialized in getOptions())
