Jim,
This has been a long standing issue with OPRA that seems to have fallen
on deaf ears. It all started when OPRA simply used the proof on concept code
that SpryWare and Pantor wrote to demonstrate the concept of FAST and released
it as a production feed. They never consulted the group to review their
implementation, in fact they distributed decoder source coded that still
contained the original proof of concept cvs version control headers.
The proof of concept code was not FAST compliant, because FAST was not even
formalized at that point. I do believe they consulted Jordan and Jordan before
releasing their version 2 of OPRA FAST, "OPRA FAST for Symbology", about
correcting the non compliant portions of the code. For some reason they chose
not to bother.
So you are left with a feed that cannot be decoded with a generic FAST decoder.
The changes are minor, simply adding a few more templates rather than having
messages templates dynamically changed based on message content.
