Re: passing element lists to cheetah template

Hi Robin,

I suspect it's search the properties of the items in the search list, so =

it is trying to find something that doesn't exist, like core.core or =

core["core"]. You probably want to explicitly list things that are being =

passed through, like:

t =3D Template(file=3D"stat.tmpl", searchList=3D[{"core":core}])

Or to be particularly lazy (I'll certainly be told off for this):

t =3D Template(file=3D"stat.tmpl", searchList=3D[locals()])

Best wishes,
Jeremy
