In Portal reports, I have a column which should display the logged in users grou

In Portal reports, I have a column which should display the logged in users group. I pass the (pp!initiator) to a rule which should return me the group name. This does not render, however if the change the rule definition to just return the groupname, it renders on the portal.
pp!initiator is returning userid when I use it in a script task inside a process and username when I use it in portal reports. Unable to figure out what is worng here. Anyone faced this before?...
