Hi all, I’ve got my UBIComponent that tracks what doc id’s a user is seeing
working great in a single node situation. The logic runs as part of the
public void process(ResponseBuilder rb) method: [1]
The component requires that the documents to be returned have been added to the
ResponseBuilder already, and so in a distributed path with the
distributedProcess() [2] call I keep getting errors that they haven’t been
populated…
java.lang.NullPointerException: Cannot read field "docList" because the return
value of "org.apache.solr.handler.component.ResponseBuilder.getResults()" is
null

org.apache.solr.handler.component.SearchHandler.processComponents(SearchHandler.java:552)

I am looking for some examples of where components have done something with the
docs before returning them to the user to get some insights into how to get
this working! Any pointers?
