Hi Roger,

Have you tried to at an at before the Model like this:

var item = @Model.NodeById(1150).Children.Random();

Maybe this little change wil solve your issue with the random method.

/Dennis

Thanks Dennis,

Here is the entire macro with your update, but no change.

@inherits umbraco.MacroEngines.DynamicNodeContext

@{
     var item = @Model.NodeById(1150).Children.Random();
     <div>
          <blockquote>@item.quoteText<span>- @item.quoteSignature</span></blockquote>
     </div>
}

And the entire error from the log.

BTW..even if I remove the div and everything inside the div, it still fails with the same error

Okay,

Don´t know if this can help you on the right way

Hi Roger,

Seems odd, I just tried this sample and it seems fine....

var a = Model.AncestorOrSelf(1).Children.Random();
<p>@a.Name</p>

Has your site always been v4.11.10 or has it been upgraded from an older version?

Perhaps check the assembly version on umbraco.MacroEngines.dll, on my v4.11.10 site I have 1.0.4926.14936

Jeavon

Hi Jeavon,

Yes odd indeed. The site was created as a 4.11.10 site, no upgrades. The fact that this code works in another 4.11.10 instance makes me suspect some different dll's were used between the two types of installers, but I even went to the site where this code works, copied the Umbraco.MacroEngines.dll, the System.Web.WebPages.Razor.dll and the System.Web.Razor.dll over to the site where it is not working, but no luck there either.

-Roger

Hi Roger,

I would try copying a complete clean v4.11.10 over the top (backup first) and then use source control to see if there were any differences.

I haven't used it but I think uDiff would also do the compare for you.

Hi I'm receiving a similar error  Umbraco v6.1.4

'umbraco.MacroEngines.DynamicNodeList' does not contain a definition for 'Any'

It works fine on my dev environment but not in my staging environment. 

I did a clean copy of all the DLL's but I still get the same error

Anton - I don't know if this would help you specifically, but there were some issues with 6.1.4 and 6.1.5 was released very quickly afterwards. Upgrading may help

Hi Steve

Thanks. I'm really at a loss here.

The original install was on version 6(All worked fine).I then upgraded to 6.1.4 when the error started happening.

I did do an upgrade to 6.1.5 but to no avail.

As I mentioned everything works fine on my dev box and development server but I don't have access to the staging and production server of my client(ftp only).

Something changed with the umbraco build between 6 and 6.1.4 which breaks on my clients servers.

At the moment is is a guessing game.

Any Ideas welcome.

Try remove the @ from before Model.. i've had issues with that between environments before

Here's some code I have that does very similar to what you're trying, maybe that'll help.

@inherits umbraco.MacroEngines.DynamicNodeContext
@using umbraco.MacroEngines
@{
    var startNodeID = Parameter.TestimonialsFolder;

    if (!String.IsNullOrEmpty(startNodeID))
    {
        var startNode = Library.NodeById(startNodeID);

        if (startNode.TestimonialItems.Any())
        {
            var testimonialsCount = !String.IsNullOrEmpty(Parameter.TestimonialsCount) ? Convert.ToInt16(Parameter.TestimonialsCount) : 99;
            var nodes = startNode.Descendants("TestimonialItem").Random(testimonialsCount);

            if (testimonialsCount > 0 && nodes != null)
            {
........

Sorry I just read your original post properly, you don't have the @ symbol on there. Anyway maybe my code will help.

Have you tried to redeploy the site to the server? Maybe under a separate IIS website?

Not sure what else to suggest... sounds like a bit of a doozy. Good luck

Hi Anton,

What version of v6 did it work fine for you pre upgrade? I would like to try to reproduce, also what is the code that fails for you?

Thanks,

Jeavon

I upgraded from 6.00 which worked fine.

As I mentioned on my servers which is set up properly all is working well, but on these numbnuts' servers it ain't.

I have no access to them so I'm shooting in the dark.

The code:

@inherits umbraco.MacroEngines.DynamicNodeContext

@using Umbraco.Core.Services;

@{

var selection = @Model.AncestorOrSelf().Descendants("Department");

}

@*Determine if there are any nodes in the selection, then render list *@

@if(selection.Any()){ <----YSOD

Hi Anton,

The only problem with that snippet is the @ before Model,

Should be:

@inherits umbraco.MacroEngines.DynamicNodeContext
@using Umbraco.Core.Services;

@{
var selection = Model.AncestorOrSelf().Descendants("Department");
}

@*Determine if there are any nodes in the selection, then render list *@

@if(selection.Any()){
}

I keep getting 'umbraco.MacroEngines.DynamicNodeList' does not contain a definition for 'Any' whenever we install DotNetOAuth or WebGrease. As soon as the dlls are removed from the bin folder everything works fine.

Although we have a "fix" it's not really a fix because we need the libraries. 

Have you got either of those (or another custom library) installed?

Tim ,absolutely, there is something bad in WebGrease that can do this, however I have found that the current version v1.5.2 doesn't have the same issue have you tried the latest version?

Jeavon, I got to the bottom of it as we're using Bundling on other sites, in my case it was that we hadn't uploaded Antlr3.Runtime.dll but I've not got to the bottom of the issue with the OAuth stuff

is working on a reply...
