The purpose of connection warnings is to let the filter author know that a particular connection of a component to a particular input is undesirable: it lead to non-intuitive filter controls or filter errors.

Here are the key facts about connection warnings:

- To fix a connection warning, follow the recommendations in its properties (see the picture above).
- Filters with a connection warning are not accepted into the Filter Library (they are blocked by the Submit Wizard).
