Call proxy service from other proxy service with attachment

Question

Hi!
I have got an email sending proxy service I would like to call this from an other proxy service and I want to send attachment in email. I can send email with attachment if i call this proxy as a webservice (e.g. from soapUI)
But if i want to call this email proxy service from other proxy service, the attachment in email is empty. I put a log action (expression: $attachments) in the beginning of email proxy service, and I saw this in the log file:
+<con:attachments xmlns:con="http://www.bea.com/wli/sb/context"/>+
So the attachment is really empty...
I use service callout. I put an insert action in request action of service callout:
In Variable:
attachments
XPath:
+.+
Location:
as first child of
Expression:
+<con:attachment xmlns:con="http://www.bea.com/wli/sb/context">+
+     <con:Content-Type>application/octet-stream</con:Content-Type>+
+     <con:Content-Disposition>attachment; filename="{$v_fileName}"</con:Content-Disposition>+
+     <con:Content-Transfer-Encoding>base64</con:Content-Transfer-Encoding>     +
+     <con:body>{$attachments/ctx:attachment/ctx:body/*}</con:body>+
+</con:attachment>+
Why cannot I call this email proxy service from other proxy service for sending email with attachment?
I tried to solve this other. I called an email sending business service from this proxy service. But in this case I cannot set the body of email. If I put just one Transport Header action in publish action, I could send the email (with empty body). But If I put a replace action in publish action as well then the OSB didn't send the email and I couldn't find any error message in log file... How could I set the body of email in publish action?
Thanks!

You should be able to get the current user id from the SPListItemEventProperties object. From here you should be able to create a Claim. For example get the user by using
user = SPWeb.Users.GetByID(properties.CurrentUserId)
SPClaim claim = SPClaimProviderManager.CreateUserClaim(user.email, SPOriginalIssuerType.TrustedProvider, issuerIdentifier);
