Hey there,
here's my problem:
a) the action:
public class SomeAction ... implements ModelDriven<SomeModel> { ...
public SomeModel getModel() {...}
... }
b) the model:
public class SomeModel implements Serializable {
...
public List<Map.Entry<String, String>> getMessageTypes() { ... }
public String getRaggedyAndy() { ... }
... }
c) in the jsp:
<s:textfield ... name="raggedyAndy" />
<%-- works, finds the model object in the value stack and uses its
getters/setters --%>
BUT:
<s:select list="messageTypes" listKey="key" listValue="value" ... />
results in:
...
Caused by: tag 'select', field 'list', name 'messageType': The requested
list key 'messageTypes' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]

Although if I understand the spec. correctly, it should also find the
model object on the value stack and use its corresponding getter. I've
even added a getter with the same name (returning eventually physically
the same list) but it doesn't make any difference.
Note: one might argue that the return type of the getter is too
"strange" but according to the specification it should be fine (I also
tried with a simple map first btw.) and the getter "getMessageTypes()"
isn't even called at all anyway.
Thanks for any help,
Agoston
