Jim Musil updated SOLR-7046:
----------------------------
Description:
When you attempt to group by function using the query() function, it results in
an NullPointerException.
Using the example webapp loaded with the hd.xml file in exampledocs, you can
recreate by issuing the following query:
http://localhost:8983/solr/select/?q=*:*&group=true&group.func=ceil(query({!type=edismax%20v=$q}))
This appears to be due to a small bug in the following file:
{code:title=Grouping.java}
protected void prepare() throws IOException {
Map context = ValueSource.newContext(searcher);
groupBy.createWeight(context, searcher);
actualGroupsToFind = getMax(offset, numGroups, maxDoc);
}
{code}
The variable context is always null because it's scope is local to this
function, but it gets passed on to another function later.
The patch is simply removing the Map qualifier from the instantiation.
