Re: [dotNetRDF-bugs] Problem with aggregate

[Tomasz P. <tom...@gm...>]

Indeed the problem was with ValuedNodeExtensions.

I filed a bug and completed your test so that the bug is reporduced
and fixed. However I have tracked a some other examples of number
parsing code, which didn't use invariant culture. Please have a look
at the changes in branch CORE-344 and decide what other tests would be
good to have to ensure no regression.

Thanks,
Tom
