------------------------------------
Summary: Self spatial-intersect on optional attribute fails
Key: ASTERIXDB-1210
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1210
Project: Apache AsterixDB
Issue Type: Bug
Reporter: Ian Maxon
This query:
use dataverse test;
for $x in dataset ds_set
where spatial-intersect($x.fc,$x.fc)
return $x
On this schema:
create type t_record as closed {
fa : int64,
fb: int64?,
fc : point?
}
create dataset ds_set (t_record) primary key fa;
create index bidx on ds_set(fb) type btree;
create index cidx on ds_set(fc) type rtree;
Fails to compile for some reason, with this stack trace:
java.lang.NullPointerException
