             Summary: Issues with applying row based security
                 Key: TEIID-2939
                 URL: https://issues.jboss.org/browse/TEIID-2939
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 8.4
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.7.1, 8.8


If a view over a left outer join has a row condition and is used in a simple aggregation:

select count(*) from vw

Then a null pointer exception will occur when considering optional joins.

If intervening criteria is added:

select count(*) from vw where ...

we can get past the initial error, but will fail in initializing the join node with an assertion error.  Both of these have the same root issue, which is our attempt to make the logic selective about when assign output elements is run, which leads to the output elements not being in place when later needed.
