[xsd-users] Problem with duplicate Ids

[BURGESS, Mark, FM]

Our firewall didn't like me including an exe in the zip file so I have
resent without.

Hopefully this one will get through...

Hi Boris,

Thanks for taking a look. Sorry the initial question wasn't clear, I just
cut and pasted the problem from my original code in case you could see
immediately what I had done wrong.

I have now created a cut down complete example which exhibits the same
problem. If you could take a look I would appreciate it since I'm stumped on
this one.

Thanks,

Mark.

The duplicate_id exception is thrown if you try to insert a duplicate ID
into a document tree. XML Schema requires IDs to be unique in the context of
a document.

I looked at you code and I can't see right away where the duplication could
happen (though note that it differs from what you described above, e.g., I
don't see where you pass "ExecutionOperation:3"). I also cannot build and
debug your code since it is not complete. What I suggest you do is catch
this exception and print the ID that is causing the problem. This will
hopefully give you some hints. If you still can't find the reason, it would
be helpful if you could create a minimal example that reproduces the
problem.

BTW, you should use ares::ExecutionEnvironment::MarketDataContext::type
instead of the above. All names that start with _xsd_ are for internal use
and may change in a backwards-incompatible manner. This is also described in
the manual:

See Section 2.8, "Mapping for Local Elements and Attributes".
