Hi
Thanks for the advice, but if I try that, I get
: _o80 node-down:
(_o87 cmd line 1)
invoked from within
"_o87 cmd node-down"
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" $..."
(procedure "_o87" line 2)
(SplitObject unknown line 2)
invoked from within
"$mac_(0) node-down"
(procedure "_o80" line 3)
(Node/MobileNode node-down line 3)
invoked from within
"_o80 node-down"
Do you have any idea what that might be about?
