[jira] [Reopened] (SOLR-3336) SolrEntityProcessor should substitute
params at query time, not startup time
[ https://issues.apache.org/jira/browse/SOLR-3336?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

The fix is not complete. Although the variable substitution was moved to the doQuery() method but because of the initDone boolean flag, the doQuery method is actually executed only once. Hence subsequent executions of child SolrEntityProcessor will either return records from the first execution or return no records at all.

> Project: Solr
> Issue Type: New Feature
> Components: contrib - DataImportHandler
> Affects Versions: 3.6, 4.0-ALPHA

> Attachments: SolrEntityProcessor.java

> The SolrEntityProcessor performs variable substitution at startup, not at query time. This means that this technique cannot work:
> {code}
> <entity get a document>
> <field SomeField/>
> <entity SolrEntityProcessor query="${SomeField}"/>
> </entity>
> {code}
> The SEP should substitute the new value of SomeField into each query string.
