[richfaces-issues] [JBoss JIRA] Commented: (RF-5772) OL/LS: NullPointerException when value is Map-bound

[ https://jira.jboss.org/jira/browse/RF-5772?page=com.atlassian.jira.plugin... ] nimo stephan commented on RF-5772: ---------------------------------- You can reproduce the NPE by the following code: Use RichFaces 3.3.0 and SEAM 2.1.1 (The failure does NOT occur if using RichFaces 3.2.2 and SEAM 2.1.1 !) In the view, take a rich:listShuttle and bound the sourceValue to a map called 'myMap'. <rich:listShuttle sourceValue="#{myMap['all']}" targetValue="#{myMap['selected']}" var="m"> <rich:column> <h:outputLabel value="#{m}"/> </rich:column> </rich:listShuttle> The map 'myMap' has a key 'all' which is filled via SEAMs Factory-Method: @Name("myView") @Scope(CONVERSATION) public class MyView { @Out(required=false) private Map<String,List <String>> myMap; @Begin(join = true) public void init() { List<String> locals = new ArrayList<String>(); for(SelectItem i: LocaleSelector.instance().getSupportedLocales()) {locals .add(i.getValue());} myMap= new HashMap<String, List<String>>(); myMap.put("all", locals); } Now, go and render the view with the 'rich:listShuttle' bounded with 'myMap'.
