[Users] null script variable value in tw_append

8 Jun 2007

if i have

modparam("tm", "tw_append",
"params:P-X=$avp(i:100);P-Y=$var(foo)")

and assign null to both $avp(i:100) and $var(foo) before t_write_unix(),
then P-Y is appended (with value 0), but P-X is not.

in my opinion, also P-Y should not be appended, i.e., script variable
value null should be treated the same way as pseudo variable null
value.
