Dale LaBossiere updated QUARKS-120:
-----------------------------------
    Summary: bad graph generation with certain API / oplet sequence  (was: =
Counter oplet looks like a source for complex tuple type)

> In the graph for TopologyTestBasic, a counter oplet appears to be a sourc=
e (i.e. there's no other oplet pointing to the counter oplet).  This looks =
odd to me - is this expected?
> Note this source uses a complex tuple type, i.e. a tuple is a Java object=
.
> The oplets 130, 77, 76 look odd - is this graph starting at oplet 130 exp=
ected?
> 130 is a counter oplet that looks like a source.
> 77 is a fanout=C2=AC (see View all oplet properties table below).
> There is tag "mcs1".=20
> See attachment for screen shots.
