I am trying to create a dynamic form on my web app, and thought the map based action form would be my best choice (I am wedded to struts). I will be putting up x amount of properties, some single select, some multiple select. However, when I write my unit tests , I am seeing that struts will not put a String[] into a mapped property - it will only take the first value - here's my test code:



I get a ClassCast Exception on this line:
String[] results = (String[]) resultMap.get("by Service Code");

Any ideas what causes this or how I can build a form that I won't know the properties til runtime ?
 
It is sorta covered in the JavaRanch Style Guide.
