Hi everyone, I would like to get the current username and use this va

Hi Tiago,
You can capture the process initiator in a user type process variable(for example processInitiator_user >> value to store in it is pp!initiator) and pass on the same as parameter configuration to the SAIL form, also if required you can add a check as mentioned below :
if(loggedInUser()=pv!processInitiator_user ,loggedInUser(), pv!processInitiator_user )
Hope it helps.

Additional information:

Per the documentation forum.appian.com/.../Scripting_Functions.html

- If there is no user context, such as when used in an expression in a node output, loggedInUser() returns "Administrator".

- In non-SAIL task forms that do not follow an activity-chained flow, loggedInUser() can be populated by selecting the Refresh default values every time the task form is viewed checkbox on the Other tab of the activity. The checkbox does not need to be selected when a SAIL form is used as it is automatically applied.

Thank you all! It works perfectly!!
Now I understand the usage of loggedInUser() according to different contexts, this actually was my problem...

Thanks for help guys!
