Ted Sullivan created SOLR-9558:
----------------------------------
Summary: DIH TemplateTransformer does not support multiple values
Key: SOLR-9558
URL: https://issues.apache.org/jira/browse/SOLR-9558
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: contrib - DataImportHandler
Affects Versions: 6.2
Reporter: Ted Sullivan
Priority: Minor
Fix For: trunk
The DIH TemplateTransformer does not support multiple templates with the same
column name. Rather than creating a List of values as it should do in this
case, the value of the last <field> tag with the same column name replaces the
values of previous transforms for that column. The reason is that it uses a
single HashMap to store the transformations with a key on column name. The fix
is to detect if a column has previously been transformed within the same field
set and to create a List<Object> for that column when this occurrs.
