SharePoint 2013 – Hover Panel Display Templates not showing Custom Columns

Custom hover panels

Today I created a custom hover panel. I took the default item_Default_HoverPanel.html from my Display Templates Gallery and added a copy as item_custom_hoverpanel to the Display Template Gallery.

I also did the same for item_default.html as there is a reference to the hover panel used in there.

The I added some extra fields to the following line:

<mso:ManagedPropertyMapping msdt:dt=string">'Title':'Title,.... </mso:ManagedPropertyMapping>

But whatever I did my properties would not appear. In the above line I added the propery:

<mso:ManagedPropertyMapping msdt:dt=string">'MyCustomManagedProperty':'MyCustomManagedProperty','Title':'Title,.... </mso:ManagedPropertyMapping>

I created a Managed property and checked the properties many times. I ran a full search crawl , still no luck.

I even added the property to a Refinement panel aha it appears in the refinement panel. So this is the proof that the managed property works.

Your solution

I added the same custom property to my item_custom.html

<mso:ManagedPropertyMapping msdt:dt=string">'MyCustomManagedProperty':'MyCustomManagedProperty','Title':'Title,.... </mso:ManagedPropertyMapping>

And now my hover panel suddenly shows my properties. Why??

The item_custom/item_default.html builds up the ctx object and this is not updated by hover panels. Therefore cts.CurrentItem isn’t changed when my hover panel uses additional Managed properties.
