Hi all,
trying to POST to .../update/json/docs, payload includes
"DISPLAY_MAPPING" : "foo", and the result is a 500 with
```
null:org.apache.solr.common.SolrException: copyField dest
:'doc.DISPLAY_MAPPING_str' is not an explicit field and doesn't match a
dynamicField.
```
Which is fine as far as that goes: the only place this can come from is
AddSchemaFields w/ the default mapping as:
```
<str name="valueClass">java.lang.String</str>
<str name="fieldType">text_general</str>
<lst name="copyField">
<str name="dest>*_str</str>
<int name="maxChars">256</int>
</lst>
```
Except that DISPLAY_MAPPING exists in the schema as
org.apache.solr.schema.StrField and I can't figure out why it is
triggering AddSchemaField on it in the first place.
Any suggestions?
TIA
Dima
