Msg: Return type of an Apex action method must be a PageReference - clues???

I'm trying to pass a dynamic picklist from my controller to my page. I've successfully used this technique in the past, but now, I get the following message:  

 

Return type of an Apex action method must be a PageReference. Found: core.apexpages.el.ApexELResolver$VisualforceArrayList 

 

This is triggered by  event="onchange"  action="{!getTeamMembers}" in the section of code associated with the "Sales Team" output label. 

 

The page code is: 

 

<apex:pageblockSectionItem >
     <apex:outputLabel value="Sales Team:" />
     <apex:selectList value="{!vChosenSalesTeam}" multiselect="false" size="1"  >
         <apex:selectOptions value="{!SalesTeams}"/>
         <apex:actionSupport event="onchange"  action="{!getTeamMembers}" rerender="USAT" />
     </apex:selectList>
</apex:pageblockSectionItem>

<apex:pageblockSectionItem >
    <apex:outputLabel value="Team Member:" for="TeamMembers"/>
    <apex:selectList id="TeamMemberList"  value="{!vChosenSalesPerson}" multiselect="false" size="1"  >
        <apex:selectOptions value="{!TeamMembers}"/>
    </apex:selectList>
</apex:pageblockSectionItem>

 

The controller is: 

 

    Public list<selectOption> getTeamMembers()
    {
       
       System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0100'); 
     
       System.debug('#################### vChosenSalesTeam: ' + vChosenSalesTeam);  
       
       List<SelectOption> TeamMembers = new List<SelectOption>();
       
       TeamMembers.add(new SelectOption('- None -', '- None -')); 

           
       for (User UList : 
          [SELECT Id, Name
           FROM   User
           WHERE  Sales_Team__c = :vChosenSalesTeam
           AND    Sales_Team__c != null  
           AND    IsActive = true
           AND    AMS_Territory__c != null
           AND    Property__c in ('1531 - Republic Media', 'NST', 'USAT', 'USAT SPORTS', 'USA WEEKEND')   
           ORDER  BY Name
           LIMIT  125])
        {
         System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0200'); 
         System.debug('#################### UList.Id: '   + UList.Id);  
         System.debug('#################### UList.Name: ' + UList.Name);  
         
         System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0300'); 
         TeamMembers.add(new SelectOption(UList.Id, Ulist.Name));  
        }      
      
       System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0400');       
       return TeamMembers;
       //return null;
    }

 

 

 

Any clues are greatly appreciated. 

 

Thanks,

 

Chuck

method should return a pagereference to a page that reflects your changes. Otherwise, it doesn't know what to display. Alternatively, Returning null should refresh the page.

Yep, thanks. I finally realized I needed a different method. 

 

Thanks for the help

 

public pageReference getTeamMembers()
{
  getTeamMembers2(); 

  return null; 

}    



Public list<selectOption> getTeamMembers2()
    {
       
       System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0100'); 
     
       System.debug('#################### vChosenSalesTeam: ' + vChosenSalesTeam);  
       
       List<SelectOption> TeamMembers = new List<SelectOption>();
       
       TeamMembers.add(new SelectOption('- None -', '- None -')); 

           
       for (User UList : 
          [SELECT Id, Name
           FROM   User
           WHERE  Sales_Team__c = :vChosenSalesTeam
           AND    Sales_Team__c != null  
           AND    IsActive = true
           AND    AMS_Territory__c != null
           AND    Property__c in ('1531 - Republic Media', 'NST', 'USAT', 'USAT SPORTS', 'USA WEEKEND')   
           ORDER  BY Name
           LIMIT  125])
        {
         System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0200'); 
         System.debug('#################### UList.Id: '   + UList.Id);  
         System.debug('#################### UList.Name: ' + UList.Name);  
         
         System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0300'); 
         TeamMembers.add(new SelectOption(UList.Id, Ulist.Name));  
        }      
      
       System.debug('#################### USAT_GD_ShareRefPageExtension MilePost getTeamMembers-0400');       
       return TeamMembers;
