Symptoms

I have some outgoing task emails which contain reference to smartobject data.

At the end of the email, all of the reference variables are echoed out again, all in one block.

There are no contents in the email editor, after the light-grey text.
 

Diagnoses

If you open up the Client Event in the WF, goto the Notification Panel, click Customize Mail? click into the Mail Area and Select All (Shift A), you will most likely see that it seems to be selecting a bunch of empty spaces at the bottom of the mail. Support has observed this happen before where the artifacts (those green datafields) duplicate invisibly at the end of the Mail Template in the Wizard for no good reason.

 

Resolution

Two methods are available to fix the issue.

Method One.

Just select all that empty space at the bottom and delete, then redeploy.

Method Two.

Deleting and recreating the Mail Event should resolve it
