Cannot use Map with 7.0.0-pr6

[manosbatsis]

This works (kotlin):

@OneToMany(mappedBy = "account")
 val reserves: List<Reserve> = emptyList()

But this:

@MapKey(name = "currency")
@OneToMany(mappedBy = "account")
val reserves: MutableMap<String, Reserve> = mutableMapOf()

Results in error:

Elide doesn't support maps as relationships because JSON-API doesn't have a similar concept.

Hey @aklish , thanks for the reply. Actually when a @MapKey is present, Elide can simply treat the example as if it where:

@OneToMany(mappedBy = "account")
val reserves: MutableList<Reserve> = mutableListOf()
