Re: getting the xml data from a dispatched event

I'd add a trace statement just before it to see what type of object
event.target is - it could be that the target is the UI component, and
not the data object.

//throws error on this line
trace(event.target);
customMeals.addItem((event.target as mealitem).mealDetails);
