Display a RefinableDate as Slider Refiner

Something has changed in the search.clientcontrols.js script. Before the RefinableDate managed properties were mapped as DateTime (which is now changed to ECMADATE). Now with the script update, they are mapped as EcmaDateRefinersInvariant which does not contain the date range labels.

As an example, I added the same date ranges also for the EcmaDateRefinersInvariant type:

Which renders this result:

The *bug* in the code is that the SearchType for the ECMADATE type is overwritten, first when they set the EcmaDateRefinersSingle and after that by EcmaDateRefinersInvariant. So when you use a RefinableDate or auto-created managed property (one with an OWSDATE suffix), it will always return as an EcmaDateRefinersInvariant type. Which does not contain date labels.

So IMO there are two solutions, adding the labels also for the EcmaDateRefinersSingle and EcmaDateRefinersInvariant types. Or changing the order of the registration, so that EcmaDate is registered last:

As a workaround, I have added a temporary template with fixes the issue. You can find it in the GitHub repository: https://github.com/SPCSR/DisplayTemplates/tree/master/Search%20Display%20Templates/Refiners/Slide%20bar%20graph%20for%20custom%20managed%20properties
