Behavior on non definded name in Cheetah

[Paolo Pantaleo]

[I hope I am posting to the right place]

I have a cheetah template something like this:

x is: $x
y is: $y
z is: $z

[Actually more complicated]

If for example $y is not defined I get an exception and  the parsing
of the template stops. Is  there any way to substitute $y with an emty
string and making cheeta going on with parsing?

Thnx
PAolo
