[mono-android] What´s wrong with this piece of code?

[Leighton Haynes]

I seem to recall that this line:
            IList<IDictionary<string, object>> groupData = new List<
Dictionary<string, object>>() as IList<IDictionary<string, object>>;
will fail as List<Dictionary> will not cast to IList<IDictionary>. Which
means that curGroupMap is null. I haven't thrown it at a compiler to check
though.

Cheers,
Leighton...
