Chintan, you should send this kind of messages to the users list of myfaces,
never to the developers itself if you want to have a fast answer ;-) Now I
am on holidays and I cannot help you on this, but it seems this may be a
bug. Feel free to take a look at the SelectManyListRenderer class on the
sandbox sources to see if you can debug/fix the problem and submit a patch
with the possible solution in the JIRA tracker. If you don´t feel in the
mood to do that, just open a JIRA ticket with the bug,
Thanks,
Bruno

Hi Bruno,
I am facing one issues with selectManyPickList. I am putting my code here.
JSP code:
<t:panelGroup>
<t:panelGrid columns="3">
<t:outputLabel value="ABC"/>
<t:outputLabel value=":"/>
<%-- Sandbox component --%>
<s:selectManyPicklist size="10"
style="width:175px;"
valueChangeListener="#{
accessDelegationController.selectionChangedForOperations}"
value="#{
accessDelegationController.selectedOperationsList}"
immediate="true">
<f:selectItems value="#{
accessDelegationController.operationsList}" />
</s:selectManyPicklist>
</t:panelGrid>
</t:panelGroup>
Java Code:
Creating 2 Lists. one for SelectedValues and other for default values.
private List selectedOperationsList = new ArrayList();
private List operationsList = new ArrayList();
//here both lists have getter and setter method(which i have not mentioned
here)
//logic to add values in above lists. (Note: I am iterating the values
which i am getting from backend. and adding to selectedOperationList list)
List OperationList1 = (List)Service1.getCreatedOperationRulesList();
//Iterator for selected operation
Iterator iter = OperationList1.iterator();
int i = 0;
while(iter.hasNext()){
Operation operation = (Operation)OperationList1.get(i);
selectedOperationsList.add(new SelectItem(Integer.toString(
operation.getId()),operation.getName()));
i++;
iter.next();
}
//same for default operation lists
List
operationList2=(List)Service2.getOperationsList();
Iterator iter1 = operationList2.iterator();
int j = 0;
while(iter1.hasNext()){
Operation operation1 =
(Operation)operationList2.get(j);
operationsList.add(new SelectItem(
Integer.toString(operation1.getId()),operation1.getName()));
j++;
iter1.next();
}
While rendering only left-hand side value comes.( i mean operationsList).
Right-hand side box(selecteOperationsList) contains no values. though both
the lists are having values in it.
I dont know what is the problem? can you please help me?
Thanks
Chintan
