[Seaside] Handling errors - staging/production

[Boris Popov, DeepCove Labs]

John,

We use our own mail handling system on top of clients provided by VisualWorks, so verbatim examples wouldn't be helpful to you, but here are some snippets,

client := (SMTPClient new)
		hostName: host;
		user: (NetUser username: username password: password);
		yourself.
message := (MailMessage newTextPlain)
		from: from;
		replyTo: from;
		to: to;
		cc: cc;
		bcc: bcc;
		date: Timestamp now;
		subject: subject;
		text: body;
		yourself.
mimes do: [:each | message addAttachment: each].
message prepareForTransport.
client send: message.

-Boris

Can you show the actual code that you are using? I've setup Postfix relaying to GMail on my laptop, and am using the WAEMailErrorHandler, but while I can get one message sent, I then usually get a WAIllegalStateException in the image. I'm not really sure if I am handling the exception correctly, but what I want to do it log/email it, and then have the app try to continue.

Thanks.
