Problems with SingleEmailMessage and cc - salesforce

Question

I have an app that works fine if all destination fields (To:, cc:, and bcc:) are filled in, but if one of them is blank, I get an error stating there is an invalid email address. I am using text input fields and multiple email address are separated by semicolon (;). If the input field is blank I do not assign anything to that option. Any idea why this might happen? What value do I use for setCcAddress and setBccAddresses functions to show nothing. I have tried several(null, empty list).
See the code below.
Extension:
public class AffEngpdfExtension
{
public ID callersId;
private String transferUrl;
public String recipientEmail { get; set; }
public String ccEmail { get; set; }
public String bccEmail { get; set; }
public String subjectEmail { get; set; }
public String bodyEmail { get; set; }
public String docName { get; set; }
// Constructor
public AffEngpdfExtension(ApexPages.StandardController stdController) {
stdController.addFields(new List<String>{ 'Name', 'User_Email__c', 'Oversight_Email__c', 'Sales_Rep_Email__c' });
Affiliate_Consulting_Engagement__c affEngage;
affEngage = (Affiliate_Consulting_Engagement__c)stdController.getRecord();
callersId = stdController.getRecord().id;
this.recipientEmail = affEngage.User_Email__c;
ccEmail = affEngage.Oversight_Email__c + ';' + affEngage.Sales_Rep_Email__c;
List<Contact> senderEmail = [SELECT Id, Email FROM Contact WHERE pse__Salesforce_User__c=:UserInfo.getUserId() LIMIT 1];
bccEmail = senderEmail[0].Email;
subjectEmail = 'Affiliate Consulting Engagement ' + affEngage.Name + ' - ' + affEngage.Engagement_Code__c;
docName = affEngage.Name + '-' + affEngage.Engagement_Code__c;
}
public String TransferPage { get; set; }
// Action method to transfer to a PDF version of the current page !!!
// MUST set the value of TransferPage as part of this Action call !!!
public PageReference transferTopage() {
transferUrl = '/apex/' + TransferPage + '?scontrolCaching=1&id=' + callersId;
PageReference pdfPage = new PageReference(transferUrl);
System.Debug('transferTopage-transferUrl: ' + transferUrl);
return pdfPage;
}
// Email content...
public PageReference emailPdf() {
System.Debug('EmailPDF-TransferPage: ' + TransferPage);
if(String.isBlank(this.TransferPage)) {
ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR,
'Internal Error: missing TransferPage in pdfExtension'));
return null; // early out
}
if(String.isBlank(this.recipientEmail)) {
ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR,
'You must enter a Send To email address !'));
return null; // early out
}

subjectEmail = TransferPage;
}
String tempstr = this.bodyEmail;
tempstr = tempstr.replaceall('[^\\W\\D]*','');
if (String.isBlank(tempstr)) {

}

PageReference pdfPage = new PageReference(transferUrl);

try {
reportPdf = pdfPage.getContentAsPDF();
}
catch (Exception e) {
reportPdf = Blob.valueOf(e.getMessage());
}
// Create email

Answer 1

Disregard this question. My conditions for checking the email addresses were backwards. I have resolved it.
