Hi everyone,

We have an issue with a workflow we are designing in K2 (v4.5). I have added a simple ClientEvent which displays an ASPX form for reviewing documents. In this activity, I have configured my own user for testing purposes. My e-mailaddress is correctly configured.

However, when I enable the Notify destination users setting, it does not send an e-mail. I get a .NET Framework error on the MailAddress constructor claiming that "address" cannot be empty. Strange, because my e-mail address is configured properly. When I add a new E-mail Event to the same activity, it works perfectly.

Am I missing something? Any ideas how to troubleshoot further?
