Problem while Generate a PDF and Attach to an email

Question

I have implemented an Page called"attachmentPDF" with standard controller 'Contact' which having some contact details and renderAs="PDF".

Now i have implemented another page to send email with attachment of above 'pdf' file.

even though i passing contact record id for the page i am getting "System.VisualforceException: SObject row was retrieved via SOQL without querying the requested field: Contact.FirstName".

Note: if i replace another page "attachmentPDF2" with account standard controller it is working fine.

Any one can help on this.

Thanks,

Chandra

          Con = [SELECT Id,LastName,FirstName,Email,Phone FROM Contact WHERE Id=:ApexPages.currentPage().getParameters().get('id')];
          ToAddress = string.valueof(Con.Email);

public List<SelectOption> getEmailFrom() 
{
    List<SelectOption> objNames = new List<SelectOption>();
    List<OrgwideEmailAddress> org = [Select id,Address from OrgwideEmailAddress];
    for(OrgwideEmailAddress name : org)
    {
        objNames.add(new SelectOption(name.Id,name.Address));
    }
    return objNames;
}

public List<SelectOption> getMyPersonalTemplateOptions() {
    List<SelectOption> options = new List<SelectOption>();
    for (EmailTemplate t : [select Id,Name,Subject,body from EmailTemplate]) 
     {
        Maptemp.put(t.Id,t);
        options.add(new SelectOption(t.Id,t.Name));
    }
    return options;

}

public PageReference send()

    String[] toAddresses = ToAddress.split(':', 0);
    system.debug('toAddresses ######'+toAddresses );
    system.debug('Emailaddress######'+toAddresses);

    Messaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});

    system.debug('#########Result#####'+r);

    return null;

public PageReference Cancel() {
    PageReference pg= new PageReference ('/home/home.jsp');
    pg.setRedirect(true);

Answer 1

The query where you are getting contact fields on the basis of contact id, you have not mentioned FirstName field in that query.Mention that field in the query and this error will go away :)
