[ns] new router model problem

[Yuri Osokin]

Hi
 
I wrote a new router model. It worked good before I changed it a little in
C++ and changed name of the router in Tcl. And when I running the tcl it
gives me an error
 
    (_o85 cmd line 1)
    invoked from within
"_o85 cmd link _o89"
    invoked from within
"catch "$self cmd $args" ret"
    invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
    (procedure "_o85" line 2)
    (SplitObject unknown line 2)
    invoked from within
"$q link [$link_($sid:$did) set link_]"
    (procedure "_o3" line 72)
    (Simulator simplex-link line 72)
    invoked from within
"$ns simplex-link $node_bn $node_end $bottelneck 20ms MAPIIM "
    (file "multiflow_MAPIIM.tcl" line 41)
 
I guess that tcl didn't even run the simulator and C++ code. What can be the
problem ?
 
Thank, Yuri
