---------------------------------
Summary: IllegalArgumentException when using facets in union
queries
Key: OAK-9060
URL: https://issues.apache.org/jira/browse/OAK-9060
Project: Jackrabbit Oak
Issue Type: Bug
Affects Versions: 1.10.3
Reporter: Dirk Rudolph
I get the following exception when trying to execute a JCR-SQL2 query with a
facet selector and 2 path constraints, being optimised to a union of 2 queries:
{code}
select s.[jcr:path], [rep:facet(jcr:content/tags)] from [cq:Page] as s where
((isdescendantnode(s,'/content/pathA') or isdescendantnode(s,'/content/pathB'))
order by s.[jcr:content/date] desc
{code}
The same query works well with only one of the path constraints.
{code}java.lang.IllegalArgumentException: Invalid path:
rep:facet(jcr:content/genericComponent

Apparently when copying the columns in [1] the information that the column is a
FacetColumnImpl is lost because FacetColumnImpl does not override the copyOf();
