I have tried passing ${bamboo.manualBuildTriggerReason.username} as part of a string in an argument field for a command task, and it isnt being interpolated. All of the other variables work great... but this one doesnt, and I know it is in the documentation as being manualBuildTriggerReason.username -- and i know that i need to put bamboo. in front, and enclose it ins ${}.
This is for a manually triggered build, so I expected that it would work. What am I doing wrong?
