Unable to see the selected options...
Hi,
I have visualforce page which uses custom settings as select list and when I select few of the names then those needs to be displayed.
I have shown the select opions but I am not able to see the selected values in the output. (ie., after the message "You have chose" I am not getting any output.
CODE
--------
a) controller class
public class customsettingcontroller {
public string ISOSelected {get;set;}
public PageReference test() {
return null;
}
public list<SelectOption> getISOCodes() {
List <SelectOption> listCodes = new List<SelectOption>();
for (Country_Code__c cCode : Country_Code__c.getAll().values())
listCodes.add(new selectoption(cCode.ISO_Code__c, cCode.Name+'--'+cCode.ISO_Code__c));
return listCodes;
}
}
b) visualforce page
<apex:page controller="customsettingcontroller">
<apex:form >
<apex:pageBlock title="Country Codes">
<apex:selectList value="{!ISOSelected}" multiselect="true">
<apex:selectOptions value="{!ISOCodes}"></apex:selectOptions>
</apex:selectList>
<apex:actionSupport event="onselect" action="{!test}" rerender="output" status="status"/>
</apex:pageBlock>
</apex:form>
<apex:outputPanel id="output">
<apex:actionStatus id="status" startText="testing...">
<apex:facet name="stop">
<apex:outputPanel >
You have chose:
<apex:dataList value="{!ISOSelected}" var="a">{!a}</apex:dataList>
</apex:outputPanel>
</apex:facet>
</apex:actionStatus>
</apex:outputPanel>
</apex:page>
Please help me on this.
Thanks,

The apex:actionSupport needs to be between the <apex:selectList> and the </apex:selectList>
And it appears the event needs to be "onchange" for this to work.
(Plus using a String array in the controller, as per my previous reply...)
All Answers
Since the select list is multiselect, the IsoSelected property needs to be an array or list (String[] or List<String>) not just a String.
Not sure if anything else id wrong. I'm surprised you don't get an error message from this when you run the page....
Hi Aballard,
I tried both options:
1.public string[] ISOSelected {get;set;}
2. public List<string> ISOSelected {get;set;}
But I am not able to see the output. I am not getting any error message also.
Am I doing wrong elsewhere??
Thanks,
