+/**
+ * Provides access to a list through its adapter.
+ * 
+ * args: 
+ * <ul> 
+ *   <li>1-based list index (first list is used if not specified)</li>
+ * </ul>
+ * 
+ * eg: (all items of the 1st list) <code>performAction( 'get_list_data' )</code>
+ * eg: (all items of the 2nd list) <code>performAction( 'get_list_data', 2 )</code>
+ * 
+ * @return <code>bonusInformation</code>: a JSON-formatted Array<String> that is an
+ * Array of objects with a single property "value". The value of this property is generated by calling
+ * <code>list.getAdapter().getItem().toString()</code>, so make sure you implement the toString() method 
+ * on the objects that go to the adapter AND that it returns a value valid for JSON.
+ * 
+ * In ruby we can then parse the response:
+ * <pre>
+ * 		result = performAction('get_list_data')
+ * 		bonusInfo = result['bonusInformation'][0]
+ * 		JSON.parse(bonusInfo).each do |item|
+ * 			puts "#{item["value"]}"
+ * 		end
+ * </pre>
