I post this to FlexEdge (instead of FlexRadio, where it belongs)
because I want to
give everyone a chance to comment and Flex a chance to respond before the
issue is made public....

I second this statement, it is not a waste of development to make Flex software
deal with ALL issues smoothly. It is what we professionals used to
call "Professional
Grade Software". It should take whatever abuse you throw at it and
do just about
as good a job as a person could in figuring out what is wrong and
getting past it. It
is cheaper to write the code that to figure out what the user (or
your sw) did wrong,
then figure out a bypass, then document and publish it, and then deal
with all the users
who did not/would not read the doc.
It turns out that professional quality software costs about double,
to read the code while
you still understand it and ask: What could go wrong, what would I
want to do about it?
Then you write two or three lines of "no-brainer" code to handle the
situation and issue
a diagnostic about what was wrong (bad data, bad branch, bad
whatever). Do not do
what MS does and issue a blue screen of death, unless you have already written
comprehensive data to the error log.
I think Flex has not yet learned this lesson, their sw (except the
initial stages of PSDR)
just screws up, with no error log entry or diagnostic message. BTW,
if you write a
diagnostic message, be sure to include the offending data in the message:
Connot use SWR in sanity test in PSDR1013 because SWR < 1 (-3.456)
You have no idea what use can be made of that errant value when
debugging code later.
Also, professional quality sw is LOTS easier to debug later when a
user finds a problem.
Any more tips I can offer???
