    Umbraco 6.2 and lambda expression

    Razor

    Hi

    after upgraded to 6.2 version, my code doesn't work anymore.

    The problem is with this where condition:

    DynamicPublishedContent node = Umbraco.Content(1212);
DynamicPublishedContent nodeT = node.Children.Where(x => x.DocumentTypeAlias == "Indice").FirstOrDefault() as DynamicPublishedContent;

    Cannot convert lambda expression to type 'string' because it is not a delegate type

    if i try to change this code into this:

    DynamicPublishedContent node = Umbraco.Content(1212);
var nodeT = node.Children.Where("DocumentTypeAlias == Indice");

    the error became:

    Can only unbox from an object or interface type to a value type.

    any suggestion?

    Hi Alessandro,

    You have a mixture of Typed and Dynamic Models, could you try these:

    Typed:

    var node = Umbraco.TypedContent(1212);
var nodeT = node.Children.Where(x => x.DocumentTypeAlias == "Indice").FirstOrDefault();

    Dynamic:

    var node = Umbraco.Content(1212);
var nodeT = node.Children.Where("DocumentTypeAlias == @0","Indice").FirstOrDefault();

    And see if either work?

    Great, Im not sure exactly but you can't use a lamda expression with dynamics so it's strange that it worked previously.

    A lot has been changed to IPublishedContent between v6.1.6 and v6.2.0 so something must have been "corrected".

    Was your code in v6.1.6 exactly the same as this?

    The old code 

    DynamicPublishedContent node = Umbraco.Content(1212);
DynamicPublishedContent nodeT = node.Children.Where(x => x.DocumentTypeAlias == "Indice").FirstOrDefault() as DynamicPublishedContent;

    works like a charm with version 6.1.6.

    Can you point me to the docs with the changes to IPublishedContent between v6.1.6 and v6.2.0 so i can refactor my other code?

    thanks

    Yes, I have just tested to confirm myself. All changes in v6.2 are listed here, however I think this is possibly a unintended breaking change as the result of something else being changed.

    You should raise a issue here and assign to Stephan
