If a PMC class factory is not found, COBIA_createInstance returns no error, but a null pointer for the PMC, typically leading to a crash.

COBIA registration of COM objects (via COMBIA) allows for specifying a ProgID, but not for a VersionIndependentProgID. It is conceivable that COM PMEs use a VersionIndependentProgID to store the PMC's identity.

VersionIndependentProgID should probably be added to COBIA.

COBIA currently filters out all COM objects that implement {678c09a1-7d66-11d2-a67d-00105a42887f} (CAPE-OPEN Component) and filters off any object that exposes which thermo it consumes if also present is that thermo 1.1 is not supported.

This is incorrect in two ways:

• it will add components that do not indicate that they consume thermo, but do list {678c09a1-7d66-11d2-a67d-00105a42887f}. This includes e.g. thermo systems, which are clearly 1.0 only and should not be picked up by COBIA, and

• it will fail to pick components that should be picked up but do not implement {678c09a1-7d66-11d2-a67d-00105a42887f} nor indicate that thermo is consumed, which includes perhaps some unit operations.

Suggested fix:

• make a list of primary PMC cat-ids of which at least one must be implemented for a COM component to be picked up by COBIA for CAPE-OPEN versions prior to 1.2 - after that it will not be an issue as the CAPE-OPEN Component Key will suffice.
