Using a rotated coordinate system

I am trying to use a rotated coordinate system to specify a heat source BC, but it seems that Comsol doesn't recognize the names of the coordinates. For example if I keep the default names for the coordiante system and axes and try to formulate the simple BC: 'sys2.x1[W/m]', I get the message "unknowen variable sys2.x1[W/m]". The same happens if I try to use 'x1' without the sys2. prefix.
Contrary to that, I tried defining a cylindrical coordinate system and have no trouble using it (the function sys3.r[W/m] shows no error messages)
Help would be most appreciated.
Thanks.
