Error: cannot load from non primitive location

hi,..

I was getting this error: cannot load from non primitive location, when i was declaring the given structure and initializing in the task void hmi(),... when i debugg this i found that all vaiables are initialized except that function pointer i.e. (*command)(short).  and the error is showing "Cannot load from non primitive location".

typedef struct
{
    char menuDescription[20];
    short menuItemNumber;
    short nextItem;
    short previousItem;
    short upMenu;
    short downMenu;
    _Bool (*command)(short);
}menu;
