Email Variable for Manual Action

Is it possible to use a variable for the 'Responsible Principle' value of the Manual Action task ?.

We are using different groups of people to handle deployments to development and Productions systems and are using linked action groups - so using a variable which links to an active directory user or group would solve this problem for us.

Yes it would, but the editor UI may attempt to validate the credential. The way to get around this would be to edit the Action XML directly and replace the principal name with %VARNAME%.

We'll add a fix in a future version of BuildMaster (likely 4.x) to bypass this validation if %[A-Z]% or something is matched.
