Re: [ns] ns-2.1b8 & MNS v2

O.k. the problem is in 'tcl/mns_v2.0/ns-mpls-simulator.tcl':

Simulator instproc MPLSnode args {
       $self instvar linked_mplsnodes_

       # let node_factory_ indicate MPLSnode(class)

       set tmp [Simulator set node_factory_]               <<== HERE

       Simulator set node_factory_ MplsNode                <<== HERE
       
       set n [$self node]
       
       lappend linked_mplsnodes_ $n
       
       Simulator set node_factory_ $tmp                    <<== HERE

       return $n
}


The 'node_factory_' setting is old-style and not recommended to be used.
It results in 'target_' pointer being set to NULL.
Does anybody know how to solve this problem?
