I have a lookup field and a extenstion to convert the lookup as a select list. Debug log is showing options, but the VF page is not... Any ideas of why the select options aren't populating? 
 

public class BIWorkOrder {
    public Work_Order__c wo {get; set;}  
    public list<Deployment_Cycle__c> Deployments {get;set;}
    public List<SelectOption> options {get; set;}
    public BiWorkOrder(ApexPages.StandardController stdcontroller)
    {
        this.wo = (Work_Order__c)stdcontroller.getRecord();
        getItems();

    }
     public List<SelectOption> getItems() {
        Deployments = [SELECT ID, Deployment_Date__c from Deployment_cycle__c where Deployment_Date__c > :system.Today() and Active__c = true order By Deployment_date__c ASC];
        list<selectOption> options = new List<selectOption>(); 
        for(Deployment_Cycle__c d :deployments)
        {
           string newDate = d.Deployment_date__c.month() + '/' + d.deployment_date__c.day() + '/' + d.deployment_date__c.year();
           options.add(new selectOption (d.id, newDate));
        }
         system.debug(options);
 return options;
         
    }
}

 

<apex:pageBlockSection title="BI Fields" columns="2">
                <apex:inputField value="{!Work_Order__c.Resource__c}" required="false"/>
                <apex:selectList value="{!Work_Order__c.Deployment_Cycle__c}" > ---> Lookup field
                <apex:selectOptions value="{!Options}"></apex:selectOptions>  ---> Options 
                </apex:selectList>
                <apex:inputField value="{!Work_Order__c.Due_Date__c}" required="false"/>
                <apex:inputField value="{!Work_Order__c.Notes__c}" required="false"/>
                <apex:inputField value="{!Work_Order__c.Date_Complete__c}" required="false"/>
                         
            </apex:pageBlockSection>
