Hi

Umbraco 7.1.6.

so I'm using a lambda expression to lookup a few nodes but when I try to do a where based on one property value I always get children could not be evaluated.

code being

foreach (var productCategory in Umbraco.TypedContent(1115).Children.Where(a => a.HasValue("highlightMapType") && a.GetPropertyValue("highlightMapType") == "Yes" )) ...

the foreach does not execute as nothing is returned. When I debug and inspect the lookup into another variable, where I should get a list of published content I get "children could not be evaluated".

Now, if I try

foreach (var productCategory in Umbraco.TypedContent(1115).Children.Where(a => a.HasValue("highlightMapType") ))

this works fine, but still returns unwanted items.

Not sure if it's a bug but the code can see the property, can see that it has a value, but cannot evaluate it. On the later foreach, where I get all items and then I print out the property value separately I get the property perfectly - "Yes" or "No".

Casting the generic type to bool will also give me the infamous children could not be evaluated.

As a last resort I could do an if inside the foreach as I know that I can get the property value, but this would be really inefficient.

Wondering if it's a bug or an issue that you guys have had and there's a small gotcha?

Cheers!
