Using Map for a @DataModel

[benmoore]

Hi,

Chapter 29.10.1 says @DataModel can be used on a Map and that each row of the DataModel is a Map.Entry. The wiki sample does this, then uses the Map in an h:dataTable.

However, I'm not able to get this to work, and it looks like others aren't, either.

What's going on? Here's my code:

@Scope(ScopeType.APPLICATION)
@Name("propertyManager")
@Startup
public class PropertyManagerAction implements Serializable {
  ...
  @DataModel
  private Map<String, String> properties;
  ...

<h:dataTable value="#{propertyManager.properties}" var="propertyMap">     
  <h:column>
    <f:facet name="header">key</f:facet>
    <h:outputText value="#{propertyMap.key}"/>
  </h:column>
  <h:column>
    <f:facet name="header">value</f:facet>
    <h:inputText value="#{propertyMap.value}"/>
  </h:column>
</h:dataTable>

Please, please help...

#{propertyManager.properties} is not your @DataModel.  Your @DataModel is #{properites}.

Perfect... thanks! One remaining question: changes in the form don't change the backing Map, even though the javadoc for Map.Entry says changes to Map.Entry instances are reflected in the Map.

It appears as though the <h:inputText value="#{propertyMap.value}"/> instances need a binding attribute. Is that right? What am I doing wrong?
