phpnut a75e08976f Merging fixes and enhancements into trunk
Revision: [2025]
A little more work on plugin to set some default routing.

Revision: [2024]
Changed DboSource::field() so the name() is not called for some field variables.

Revision: [2023]
Changes made in [2022] should only check if the $conditions is not empty.

The Model.field name conventions must be used for this to work.
