Did you also check that this $param is correctly set a value in your
velocity code ?
The fact that "param" is undefined on javascript side is strange, if it
didn't find anything in the velocity context, it should contain exactly the
string '$xcontext.macro.params.parameter', not undefined.
So it seems to me it was found in the context, but it has null value.
