Hello

2013-03-07 11:00:18,027 ERROR [freemarker.runtime]

Expected hash. WorkflowVariables["valideur_dsi"] evaluated instead to freemarker.template.SimpleSequence on line 1, column 14 in mail_valide_doc_dsi.
The problematic instruction:
----------
==> ${WorkflowVariables["valideur_dsi"].firstName} [on line 1, column 12 in mail_valide_doc_dsi]
----------

WorkflowVariables["valideur_dsi"] return the value stored into the Workflow named valideur_dsi => username.

If you want the firstname, you will have to fetch the Profile Object of the user.

I have no easy in my head now to help you to fetch that. My ideas would be to store also the firstname and last name by automation, but that a bit ugly... Maybe someone can help ?

Hi,

You can use Fn.getPrincipal("userName") to get the infos:
/>

${Fn.getPrincipal("userName").firstName}

If you can't hard-code the name, then you must use an intermediate variable to store the information. In an automation chain in the Studio for example, you'll have something like this:

[...previous actions...]
Execution Context > Set Context Variable
    name:  zeUser
    value: @{WorkflowVariables["valideur_dsi"]}
Notification  Send E-Mail
[...next actions...]

In the template of the eMail, you use Fn.getPrincipal((zeUser):

Bonjour ${Fn.getPrincipal(zeUser).firstName}  ${Fn.getPrincipal(zeUser).lastName},
...
