-----------------------------------------
The fix works, but i need to write a unit test for this behavior. [~dsmiley] my
you can forward this issue to the responsible person, in the meantime i will
try to implement a test, thx a lot.

> Key: SOLR-13966
> URL: https://issues.apache.org/jira/browse/SOLR-13966
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Schema and Analysis, UpdateRequestProcessors
> Affects Versions: master (9.0), 8.3, 8.3.1
> Reporter: Thomas Wöckinger
> Priority: Major
>
> LatLonDocValuesField is used by LatLonPointSpatialField field type to store
> doc values. It does this by encoding the two double values into a long. If
> the field is part of a document which takes place within a atomic update
> operation RealTimeGetComponent is used to load the field values from the
> index.
> If the request is a nested request (line number 654: isNestedRequest is set
> by DistributedUpdateProcessor to Resolution.ROOT_WITH_CHILDREN) all field
> values from the schema are copied into a SolrInputDocument (line 678).
> The copy is implemented by toSolrInputDocument method (line 728 of
> RealTimeGetComponent). The method retrieves the FieldType of the SchemaField
> and calls the toObject method (line 740). In case of LatLonPointSpatialField
> type, when docValues is set to true and stored is set to false, the fieldData
> is stored by a LatLonDocValuesField instance.
> The toObject method is implemented by the base class FieldType toExternal
> with the LatLonDocValuesField instance (line 373). In line 359 the method
> stringValue of the Field is called. The default implementation (line 259)
> checks if the fieldsData is either CharSequence or a Number and calls
> fieldsData.toString.
> Because fieldsData is of type Long in LatLonDocValuesField class the value is
> not decoded correctly.
> From my opinion LatLonDocValuesField must implement (override) the
> stringValue method and return the decoded value.
