When triggering a downstream build project using current build parameters a defined string parameter in the upstream triggering project is not evaluated if entered into the list subversion tags default of the downstream project.
The intent is to have a subversion tag specified in an upstream project used in downstream projects to setup the workspace. This arrangement is intended to allow the upstream project to define the svn tag for all downstream projects and still allow the dowmstream projects to be executed directly without any reconfiguration.
