> This works fine, it uses a using a List<Map> as source in #{controller.sourceList}, and it should put the selected map in #{controller.mapProperty['key']} (BTW it seems it is putting the toString() fo the map in #{controller.mapProperty['key']} instead of the Map):
> <h:selectOneMenu name="selectName" value="#{controller.mapProperty['key']}" >
> <s:selectItems value="#{controller.sourceList}" var="item" label="#{item['label']}"/>
> </h:selectOneMenu>
> This crashes (the difference? I added a noSelectionLabel):
> <h:selectOneMenu name="selectName" value="#{controller.mapProperty['key']}" >
> <s:selectItems noSelectionLabel="Please select item" value="#{controller.sourceList}" var="item" label="#{item['label']}"/>
> </h:selectOneMenu>
> Stack trace:
> java.lang.NullPointerException: Argument Error: Parameter targetClass is null

> I think that the problem is that it can not determine the right type for the #{controller.mapProperty['key']} expression since it an entry in a java.util.Map instead of a property in a bean.
