[SR-Users] Dispatcher: ds_is_from_list does not longer populate grp_avp

[DanB]

Daniel,

Since we are still in "connected" state, one more (hopefully last) 
question on this subject:

If I set the "setid_pvar" the configuration does not longer pass 
checking (just upgraded to latest nightly 3.3.1):
"""

I define the parameter in the following way:
"""
modparam("dispatcher", "setid_pvar", "$var(setid)")
"""

Am I missing something again?


Thanks,
DanB
