I have a visualforce page that displays campaign member information (object that links the campaign and contacts). In the table I have the status column of the campgne member exposed as follows:
VF Page: 
  <apex:column headerValue="Statut">
                            <apex:selectList value="{!cmber.campMember.Status}" size="1" onchange="updateRecords();">
                                <apex:selectOptions value="{!StatusByCampaign[cmber.campMember.campaignid]}"/>
                            </apex:selectList>      
                        </apex:column>

In my apex class: 

....
 public Map<String,List<SelectOption>> StatusByCampaign {
        get {
            Map<String,List<SelectOption>> StatusByCampaign = new Map<String,List<SelectOption>>();
            for (Campaign c: getCampaignIDList()){     
                StatusByCampaign.put(c.Id, getStatusItemsFromCampaign(c.Id));
            }
            system.debug('--StatusByCampaign--' +StatusByCampaign);
            return StatusByCampaign;
        }
    }
    ...

   public List<SelectOption> getStatusItemsFromCampaign(String campId) {
        List<SelectOption> options = new List<SelectOption>();
        String query = 'SELECT Label FROM CampaignMemberStatus WHERE IsDeleted = false AND CampaignId = \'' + campId + '\'';
        List<CampaignMemberStatus> listCampId = Database.query(query);
        
        for (CampaignMemberStatus c: listCampId){
            options.add(new SelectOption(c.Label, c.Label));
        }
        return options;
    }
...

When Saving I have this error in my VF page: Erreur de syntaxe.  Valeur 'StatusByCampaign' trouvée
Can someone help me.
