Hi Tom,
attached you find my changes to fix the NPE in the JPQL compiler when
compiling an UPDATE query including a subquery.
The SubqueryNode creates a ReportQuery instance for the subquery and
then calls the subQuery method on the query's base expression passing
the ReportQuery. The issue is that the base expression is only set for a
SELECT query.
I added some code initializing the base expression for UPDATE and DELETE
queries. Most of the code to be changed/added is identical for UPDATE
and DELETE, so I decided to add a new superclass ModifyNode for
UpdateNode and DeleteNode. I also added a new method to ModifyAllQuery
allowing to set the query's ExpressionBuilder.
Please have a look at the attached changes. Thanks!
Regards Michael
