Hello, Luke!

Thanks for your MVC blog!

There is a bug with SQL CE using:

Error running Reader:
SQL Statement:
SELECT  umbracoNode.Id,umbracoNode.Text, isNull(CMSDocument.Published,0) as Published, DocType.Text as nodeTypeName  from umbracoNode Left Join cmsDocument ON umbracoNode.Id = cmsDocument.NodeId and Published = 1 INNER JOIN cmsContent ON umbracoNode.Id = cmsContent.NodeId INNer JOIN umbracoNode DocType ON cmsContent.contentType = DocType.Id and DocType.nodeObjectType = 'a2cb7800-f571-4787-9638-bc48539a0efb'  INNER JOIN cmsContentType ON cmsContent.contentType = cmsContentType.NodeId WHERE (umbracoNode.nodeObjectType = 'c66ba18e-eaf3-4cff-8a22-41b16d66a972')AND umbracoNode.ParentId <> -20And cmsContentType.alias = @Alias And isNull(CMSDocument.Published,0) = @Published

Exception:
System.Data.SqlServerCe.SqlCeException (0x80004005): The number of arguments specified for the function is not correct. [ Minimum argument count = 1, Maximum argument count = 1,Name of function(if known) = isNull ]

I think COALESCE (instead ISNULL) is more suitable for that query.

May be you could publich source code?

Thank a lot.
