Retrieving a data element in an inner collection
To retrieve a data element from an inner collection, use a composite key in a method call like the following:
String street = (String)
kc.getValueAt("customerListData.2.address.street");
You can also use the asterisk (*) to indicate that you want to return the first data element that the toolkit finds. You should not use the asterisk when there are different data elements with the same name in the same structure or when the structure is very complex because of the impact on performance.
