> Where INTERNAL schema points to JDBC native JIRA Schema (through my custom
> factory, but it only wraps passing datasource instead of user/password/url to
> db) and JIRA schema has one view and two tables (factories generate java data
> wrapped in AbstractQueryableTable)
> When running "SELECT * FROM ISSUES" all works.
> But when changing the view from UNION construction to OR - engine provides no
> results:
