Hi Frank,
For the record, local variables are not initialised to any particular
value (as opposed to global or static variables) and since statusM
is a local variable it would normally not be initialised to nil (and
certainly not initialised to any valid object instance).
In this particular case, though, we were lucky in that the value of
statusM was nil which caused the grapher to believe you had never
set the feed at all... Otherwise it would have attempted to talk to
the feed which would have failed too because as mentioned above,
the statusM variable did not yet contain a reference to a valid
object (since none was created).
Regards,
Manor.
