    How to show the retations of a nuPicker.RelationLabels on the template?

    Questions/Suggestions
    Umbraco 7

    I've got a relation between a doctor and his investigations. A doctor can have many investigations and one investigation can have many doctors.

    To select a doctor on the investigation document type, I use a nuPickers.LucenePrefetchListPicker. The relationship is bidirectional. On the doctor document type I've added a property editor nuPickers.RelationLabels. This shows me the investigations he has made.

    Inside my template on the doctor document type, I'll show the investigations he has done. Here is the property that is generated on the doctor class:

    [ImplementPropertyType("investigations")]
public object Investigations
{
    get { return this.GetPropertyValue("investigations"); }
}

    If i call this property the result is null. My question is now: How could I show all investigations of a doctor on the doctor template?

    P.S.: I'm using Umbraco 7.6

    Hi Hein,

    Have a look at this Wiki page on the GitHub project - I think it explains how to get the various Pickers' values;

    Hope that helps,

    Sorry this didn't work...

    I've added this code:

    public Picker InvestigationsLabels => new Picker(Id, "investigations");

    and calls the property using this code:

    <ul>
    @foreach (var item in Model.InvestigationsLabels.AsPublishedContent()) @* <-- on this line *@
    {
        <li>@item.ToString()</li>
    }
</ul>

    This gives me an NullReferenceException on the marked line.

    After debugging I've seen this:

    PS: OnderzoekenLabels is a translation of InvestigationsLabels.

    There is the value of the nuPicker.RelationsLabels

    How could I solve this?
