iOS Question Cannot initialize MailComposer

Private My_Mail As MailComposer
Private My_Text As MessageComposer

My_Mail.Initialize("My_Mail")
My_Text.Initialize("My_Text")

Log(My_Mail)
Log(My_Text)

<B4IMailComposer: (null)>
<B4IMessageComposer: <MFMessageComposeViewController: 0x17a41200>>

Not sure where my mistake is. B4i v1.5
