@Mapping(source = "key.locationType", target = "basicLocation.locationTypeCode")
  @Mapping(source = "detail.locationName", target = "basicLocation.locationName")
  LocationRequest toRequest(CachedLocationKey key, CachedLocationDetail detail);

i am trying to map the object basicLocation in LocationRequest. locationType comes from key and locationName comes from detail.

If i write both the mappings , there comes the below error :

@Mapping(source = "key.locationType", target = "basicLocation.locationTypeCode")     
@Mapping(source = "detail.locationName", target = "basicLocation.locationName")

error:

java: No read accessor found for property "basicLocation" in target type.

On using either one of the mappings, it works fine.

   @Mapping(source = "key.locationType", target = "basicLocation.locationTypeCode")

or

  @Mapping(source = "detail.locationName", target = "basicLocation.locationName")

but i need to map both the fields to the basicLocation object. am i missing something here ?
