[taghrid Mazloum]

Hello,

I implement a new application in NS2 but I have an error.
I want to know the changes needed for this implementation.


The message was :

    invoked from within
"if [catch "$className create $o $args" msg] {
if [string match "__FAILED_SHADOW_OBJECT_" $msg] {
delete $o
return ""
}
