Assuming you have appropriate getters and setters on your action for the
HashMap of ArrayLists, you should be able to set them using indexing
like this - 

<s:textfield name="mapOfList.key[i]" /> 
or
<s:textfield name="mapOfList['key'][i]" />

(where "i" is an integer representing the index where you want the
String set)
