Hi,
This problem is seen in more than one JSF components. The workaround is rather
surprising. Once I add the source code to my project I will analyze the bug.
In HtmlPicklistRenderer class - method encodeEnd
There is a statement -
Set lookupSet = HtmlRendererUtils.getSubmittedOrSelectedValuesAsSet(
true, uiComponent, facesContext, converter);
If the component is marked as enabled then this lookupSet will have nothing.
However if you disable the component then lookupSet will contain all the values
that are pre-selected on the right hand select list.
As of now the workaround is to initially disable the component, get the values
and then enable the component via calling some action method.

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
