Help with a select list issue

I have an odd problem I'm trying to fix.  I have a page in which I'm trying to display a multi-select list of options from a user to choose from:
<apex:page Standardcontroller="Case"
	<apex:messages />
	<apex:pageBlock title="Send an email regarding Case # {!cseNum}" rendered="{!EMAIL}">
		<apex:form >
		<apex:outputText>Select the team members to send the message to:</apex:outputText><br/>
		<apex:selectList style="width:500px" value="{!addresses}" multiselect="true" size="10" >
            <apex:selectOptions value="{!options}"/>
			<apex:outputLabel value="Subject" for="Subject"/>:<br/>     
			<apex:outputText value="{!subject}" id="Subject"/>
			<apex:outputLabel value="Body" for="Body"/>:<br/>     
			<apex:inputTextarea value="{!body}" id="Body"  rows="10" cols="80"/>           
			<apex:commandButton value="Preview Email" action="{!preview}"/>
			<apex:outputLabel value="Attach a File"/>:<br/>
		  	<apex:panelGroup >
          	<script type = "text/javascript">
				function check(obj) {
					var path = obj.value;
					var ext = path.substring(path.lastIndexOf('.') + 1);
				if(obj.size > 10240){
					obj.value = null;
					window.alert("File size can not exceed 10MB.");
					return false;
				var res_field = obj.value;   
  				var extension = res_field.substr(res_field.lastIndexOf('.') + 1).toLowerCase();
  				var allowedExtensions = ['jpg', 'jpeg', 'tif', 'pdf', 'png', 'txt', 'doc', 'docx'];
  				if (res_field.length > 0){
          		if (allowedExtensions.indexOf(extension) === -1){
               	alert('Invalid file Format. Only ' + allowedExtensions.join(', ') + ' are allowed.');
               	obj.value = null;
               	return false;
          	<apex:inputFile id="upload" accept="txt, jpg, jpeg, tif, png, doc, docx, pdf" onchange="check(this)" filename="{!fileName}" contentType="{!contentType}" filesize="1000" size="50" value="{!file}"/>
However, even though I have verified with my debug logs that the list should be populating during my tests it renders only as blank.
Here's the controller:
public with sharing class CM_URCaseEmailer {
	public String[] addresses	{get;set;}
	public String subject {get;set;}
	public String body {get;set;}
	public Boolean EMAIL	{get;set;}
	public Blob file	{get;set;}
    public string fileName	{get;set;}
    public String contentType {get; set;}
	private static String displayName	= 'do-not-reply@donotreply.com';
	private static String replyEmail = 'do-not-reply@donotreply.com';
	public List<Case> cse   {get;set;}
	public List<CaseTeamMember> team	{get;set;}
	public List<Contact> cTeam	{get;set;}
	public List<User> uTeam	{get;set;}
	public List<SelectOption> options	{get;set;}
	public List<ID> idLst	{get;set;}
	public String cseNum	{get;set;}
	// Create a constructor that populates the Issue object
	public CM_URCaseEmailer(ApexPages.StandardController controller){
		addresses = new String[]{};
		cseNum = cse[0].CaseNumber;
		subject = 'Information regarding open Case # ' + cseNum;
		EMAIL = true;
	public List<SelectOption> getItems(){
		cse = [SELECT ID, CaseNumber FROM Case WHERE id =:ApexPages.currentPage().getParameters().get('id')];
		team = new List<CaseTeamMember>();
		team = [SELECT MemberID FROM CaseTeamMember WHERE Parent.ID =: cse[0].ID];
		List<ID> idLst = new List<ID>();
		for(integer t = 0; t < team.size(); t++){
		cTeam = new List<Contact>();
		uTeam = new List<User>();
		cTeam = [SELECT ID, Name, Email FROM Contact WHERE ID IN: idLst];
		uTeam = [SELECT ID, Name, Email FROM User WHERE ID IN: idLst];
		List<SelectOption> options = new List<SelectOption>();
		if(cTeam.size() > 0){
			for(integer q = 0; q < cTeam.size(); q++){
				options.add(new SelectOption(cTeam[q].Email,cTeam[q].Name)); 
		if(uTeam.size() > 0){
			for(integer r = 0; r < uTeam.size(); r++){
				options.add(new SelectOption(uTeam[r].Email,cTeam[r].Name)); 
		system.debug('Team: ' + team);
		system.debug('ID: ' + idLst);
		system.debug('Contact: ' + cTeam);
		system.debug('User: ' + uTeam);
		system.debug('Options: ' + options);
		return options;
	public String[] getAddresses(){
		return addresses;
	public PageReference preview(){
		return page.CM_PreviewMessage;
	public PageReference back(){
		return page.CM_ClaimEmailConvo;
	public PageReference send(){
		// Define the email
		Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage(); 

    	//String address = cse[0].Contact_Email__c;
    	//String[] toAddress = address.split(':', 0);
    	//if(cse[0].Contact_Email__c != null){
        	// Sets the paramaters of the email
			email.setHtmlBody('<p>' + body + '</p>' + ' Please do not reply directly to this email, the address which sent this message is not monitored.  To send a reply regarding your claim, click the following link: "mailto:email_to_issue@7y00nkwgarhuofryox60fppai5gbe09bl5th5np38g3ud4x78.19-ddlxeao.cs24.apex.sandbox.salesforce.com?subject=Re: Information regarding open issue with Maximus Auto Group # '+csenum+'"');
    		file = file;
            if(file != null){
            Attachment attach = new Attachment();
      		attach.Body = file;
      		attach.Name = filename;
      		attach.ContentType = contentType;
      		attach.ParentID = cse[0].ID;
            Messaging.EmailFileAttachment efa = new Messaging.EmailFileAttachment();
        	email.setFileAttachments(new Messaging.EmailFileAttachment[] {efa});
			// Sends the email
			Messaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});   
			// Create and insert a new Task
			Task task = new Task(ActivityDate = Date.today(),
    		CallDisposition = 'Email Sent to Customer',
    		CallType = 'Outbound',
    		Description = email.HTMLBody.stripHTMLTags() + ' Files attached: ' + filename,
    		Status = 'Completed',
//    		Subject = 'Email to: ' + toAddress,
    		Type = 'Email',
    		WhatId = cse[0].ID);
			insert task;			
			return null;
		return null;

Any suggestions would be appreciated.
