i've added code supporting the test case you gave me. it's new and probably under-tested so feedback would be appreciated.
add this functionality was actually quite a nice test of the refactored reading code. creating special actions to provide this functionality was clean and (relatively) easy. this was one of the major aims of the refactoring and i'm now confident that the design's about right and that the code's approaching the time when it's ready to be merged back into the main stream.

Hi Robert,
I've hit a problem with Maps and arrays that I haven't been able to resolve. I would like to write/read a Map that has an array (either java array or collection) as the values of the map. When I write, everything looks ok. When I read back in, I'm getting a map with no values. If I wrap the array or collection in another bean (so the value of the map is a bean, not an array or collection), it will work. I can live with that if I need to, but I would prefer to have the map values be arrays or collections directly. I haven't been able to track down a good way to do that-- I'm hoping you'll see a relatively easy solution I'm missing :).
Below is a test case that shows the problem. Any suggestions?
Thanks, Brian
AddressBook.java --------------------------------- package org.apache.commons.betwixt.io.read; import java.util.HashMap; /** * @author Brian Pugh */ public class AddressBook { private HashMap addressesMap = new HashMap();

}
public void setAddressBookItems(HashMap map) {
this.addressesMap = map;
}
public void addAddressBookItem(String name, AddressBean[] addresses) {
addressesMap.put(name, addresses);
}
}
