just tried the community requests application.
Running Application Express 4.2.3.00.08.
When I first entered a new feature request I did not use a component, as this field is optional and I did not have any components set up so far.
I realized that my request did not show up on "Feature Requests" (Page 4), but it did come up under "My Requests" (Page 17).
After trying various things it looks like there is a bug in the region SQL for page 4, not using an outer join for component.
However I cannot confirm that, because I did not want to unlock the application.
Can someone of you either confirm it is intended to work this way or if this is a bug?
