      1. create the following view and proc:

          <model visible = "true" type = "VIRTUAL" name = "views">
        <metadata type = "DDL"><![CDATA[
          create view v as select 1 as a1 
        ]]>
        </metadata>
    </model>

    <model visible = "true" type = "VIRTUAL" name = "procs">
        <metadata type = "DDL"><![CDATA[
          create virtual procedure pr0() returns (res integer) as
          begin
            select a.a1 from (SELECT * FROM views.v p) a where a.a1 in (select a1 from a);
          end       
        ]]>
        </metadata>
    </model>

      2. run the query:

      select * from (call procs.pr0()) a

      but changing pr0 procedure on (changing sub-query in "in" clause):

          <model visible = "true" type = "VIRTUAL" name = "procs">
        <metadata type = "DDL"><![CDATA[
          create virtual procedure pr0() returns (res integer) as
          begin
            select a.a1 from (SELECT * FROM views.v p) a where a.a1 in (1);
          end       
        ]]>
        </metadata>
    </model>

      solves the NPE.
