Greetings fellow earthlings,



GoSilverlight is very cool, and we would like to continue to use this product. We are having issues here , not sure if bug or something wrong with our implementation. Here are the exception details.





error message:

{System.ArgumentNullException: Value cannot be null.

Parameter name: source

at System.Linq.Enumerable.Where[TSource](IEnumerable1 source, Func2 predicate)

at Northwoods.GoXam.Model.GraphLinksModel4.#tj(#I a) <br /> at Northwoods.GoXam.Model.GraphLinksModel4.#xj(HashSet1 seen, #I a, #I b) <br /> at Northwoods.GoXam.Model.GraphLinksModel4.#wj(#I a, #I b)

Aha – that’s actually a bug that we have already fixed, but apparently didn’t include in the latest bug fix release. Allow me to create new DLLs for you.
