Hoss Man updated SOLR-3783:
---------------------------
Attachment: SOLR-3783.patch
Thanks for reporting this Tanguy,
The NPE is definitely bad, a pretty clear oversight in the pivot facet code -
fixing it doesn't seem to be that hard.
patch includes test updated tests (which also fixes what appeared to be a
mistake in the test -- comment suggested it was checking data about the second
pivot but it was still checking hte first)
> Facet pivots produces NPE when facet.missing is turned on

> We get an http 500 as follow :
> {code:xml}
> <lst name="error">
> <str name="trace">java.lang.NullPointerException</str>
> <int name="code">500</int>
> </lst>
> {code}
> When facet.missing is turned on and combined with facet.pivot (if one of the
> pivot-faceted fields have missing counts ^-^)
> Ideally, the decission tree could be computing for the missing "entries"
> using the {noformat} -field:[* TO *] {noformat} query but it might be a
> performance issue on a large index (I guess)
> The fallback to this could be to raise a 400 error with a clean message
> telling that both parameters can't be combined and then the documentation
> should be modified accordingly.
