Getting a list of compact links for an association throws an exception [DATAREST-404]

Dave LeBlanc opened DATAREST-404 and commented

On an object that has a one-to-many association (eg: a set of things) if we get the set without a custom content type, it returns the expected results.

If however we request it in the compact type (application/x-spring-data-compact+json) - which I assume should just return a list of links, the call will throw an exception: "Map has no value for 'repository'". It's trying to build a URL with parameters: /{repository}/{id}/{property}, but all it gives for parameters is "property" -> "items" (looks like it's missing the repo and id properties).

To recreate, use this URL with the restbucks example: http://localhost:8080/orders/1/items

The stack trace is:
