Just read from the WW in action book - "One of the nicest features about the iterator tag is that it can iterate over just about any data type that has a concept of iteration. When iterating over a Map, it iterates over the Set returned by Map.entrySet(), which is a set of Map.Entry objects, which in turn has the methods getKey() and getValue() to retrieve the associated key/value pairs."
The key to retrieving the values is to use <s:property value="key"/> and <s:property value="value"/> Felipe Rodrigues wrote: > > I'm not so sure if you can iterate over a Map.
