Hi Thibaut,
=20
This is actually the same problem I ran into that I mentioned in a =
recent list post (the
issue is "NMO-44" on the jira.truemesh tracker, but doesn"t seem to be =
in the sourceforge
tracker). I"ve got a fix for it that seems to work well, but it hasn"t =
been incorporated
into the official source yet.
=20
If you"re interested, I can send you the patch and you can compile your =
own version for the
time being.
=20
John.

Hi,
=20
I"m getting a NullReferenceException while calling SetupResult for an
inherited property (full testcase below) :
- is it a know issue ?
- which tracker should I use to open an issue for that, if not know =
already ?
=20
I found a quick workaround which is to create a custom class
inheriting from DynamicMock, and override Invoke().

Hi John,
=20
thanks for pointing this out; I"ve missed the message.
=20
I can wait until it"s incorporated into the main tree, it"s just fine =
for me.
=20
Who are the committers ?
