Hello,
I have the dialect arranging a map between TimeSpan and NodaTime.Duration.
I step through several such user type conversions from and to, assembled
and disassembled, so I know that at least it should be able to handle the
use case.
However, still receiving an exception, not sure quite as to why, maybe
something TimeSpan? Nullable is appearing in the ADO recordset somehow, I'm
not sure yet.
And sorry for the mess here, the excptions, messages, and the query... The
data is all there as expected, and have traced up the callstack, up to and
including the repository pattern IQueryable query provider, everything else
being equal, the values SHOULD be landing in the mapped property(ies)
correctly.
Trouble is in an exception like this, I do not know per se "which"
properties are failing. I'll look at possibly doing some Debug writes at
strategic IUserType moments when those details, alias, etc, are better
known. Although I'm not sure exactly that will tell me property names, more
like the query alias names, which is also not especially helpful.
BTW, if it matters, the columns in question, are properly mapped in the
context of a fluent Component. This is intentionally properly the case.
I'll also have to review the component code, because I'm not hundred
percent certain those properties are not internally or privately set, with
their values either calculated or ctor provided.
Thanks!
