Sorry Frank, but I don't think you have to worry about casting at all. Say
you've collected all your values into a List (myList), as Thomas suggested -
then all you need to do is something like the following:
Class type = PropertyUtils.getPropertyType(obj, "myArray");
// Array Processing
if (type.isArray()) {
Class componentType = type.getComponentType();
// Create new instance of the array
Object myArray = Array.newInstance(componentType, myList.size());
// Get the converter
Converter converter = ConvertUtils.lookup(componentType);
// populate array values
for (int i = 0; i < myList.size(); i++) {
// Get & Convert the value
Object value = converter.convert(componentType, myList.get(i));
// Set the value in the array
Array.set(myArray, i, value);
}
// set the beans property
BeanUtils.setProperty(obj, "myArray", myArray);
} else {
// ? handle error ?
}
