Hi Jeavon,

I did try working with that example but was receving this error:

I'll give it another shot and get back to you.

Could you please post your entire file contents?

Hi Jeavon,

I just retested and posted the code below ... I really appreciate your help.

Hi Craig,

Yeah ... it wasn't a typo ... I actually wrote it that way so the alias was spot on. I tried running through another stripped down version and still no luck ... check out my post-code below.

Thanks again for your input. I think this platform is great, but documentation is miserably light. THANK GOD the developer community is SO active. You guys have been a HUGE help.

Also is this a upgrade or a new install of v7.6?

Hi Jeavon,

I appreciate the quick reply ... one quick question though ...

I think I found it ... https://github.com/Jeavon/Umbraco-Core-Property-Value-Converters/blob/v3/Docs/RelatedLinks.md

Working through the documentation ... I check back in with the results.

Thanks again!

It is a new install ... I had an opportunity to build the site from the ground up right after v7.6 was released.

So ... more details (thanks for pointing me to the github page) and a NEW error message.

I reviewed the documentation for v7.6 ... the only thing I think is not complient is that it's a "Umbraco.RelatedLinks2" picker. But EnablePropertyValueconverters is set to "true" so that shouldn't be an issue anymore, right? (see other requirements-details listed below)

[ x ] Umbraco-Core-Property-Value-Converters v3.1.3 (Installed)

[ x ] umbracoSettings.config

<!-- Enables value converters for all built in property editors so that they return strongly typed object, recommended for use with Models Builder -->
<EnablePropertyValueConverters>true</EnablePropertyValueConverters>

[ x ] /Views/Web.config

namespace added to Umbraco.Web.Models

<add namespace="Umbraco.Web"/>
<add namespace="Umbraco.Web.Models"/>

Thanks Jeavon, I'm uninstalling now. I'll check back in with you after the package is uninstalled.

That must have been it ... I just uninstalled it and rebuilt a doc type with a related links property type and BOOM ... we're in business.

This not only got an example up and running, but it got me about 90% there on the conditional statement that was using related links to help build the dynamic navigation. (which I'm happy to share with you if you're interested ... see below)

The error that's being thrown now "value cannot be null. Parameter name: source" is because the related links property data is currently stored on another page. When it's on the same page that's loaded ... it works PERFECTLY ... and the menu item is able to reference the related links caption as well as the link.

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using Umbraco.Web.Models
@*
    This snippet makes a list of links of all visible pages of the site, as nested unordered html lists.

    How it works:
    - It uses a custom Razor helper called Traverse() to select and display the markup and links.

                        }

            }
}

The error that's being thrown "value cannot be null. Parameter name: source" is because the related links property data is currently stored on another page. When it's on the same page that's loaded ... it works PERFECTLY ... and the menu item is able to reference the related links caption as well as the link.

Thank you Jeavon for helping me work through this.

So is there a related links on every childPage?

Hi Jeavon,

No. I am creating child pages that will only include the "anchorLinkOption" (a true-false data type) and the "rLinksTarget" property type to generate anchor links in a dynamically generated NAV pointing to internal content areas on a common page.

So one NAV dropdown looks like this:

The "TestPage" link is the name of a page in the content tree made from a doc type that just has those two property types "anchorLinkOption" and "rLinksTarget".

Here is the doc type with the two property types:

To use that I would need to add that namespace to the Web.config, right?

... added it ... didn't work. Threw this error:

Server Error in '/' Application.
