Linq to Umbraco AncestorOrDefault bug ?

Hello,

I was wondering if I found a bug or are just using it wrong.

If I use

from obj in ctx.SomeChild
select obj.AncestorOrDefault<AnotherType>()

I get the error below (The given key was not present in the dictionary) when SomeChild doesn't have a parent of type AnotherType.Is this error avoidable?

Thanks

Teus

See if there's a bug on codeplex already and if not can you lodge one.

I haven't used it since I wrote that though.

Hi There,

Is there any solution for this ?

I try to get all child nodes of particular type which give me the same error.

The given key was not present in the dictionary

For example get all news item in news category

newsCat.NewsItems.ToList();

How do you get the child node of particular type in umbraco ?

Thanks
