Current behavior

When configuring schema.index at object instance returned by SchemaFactory.createForClass its returns a error during dev runtime. The type of first argument of schema was any and now has type of IndexSpecification.

Expected behavior

I always declare a compound index using this sintax XptoSchema.index({ field1 : 1, field2 : 1 },{ unique:true }) but now I'm getting this trouble described below.
