I haven't used it myself but studied the source code of
Zend_Db_Table_Abstract and Zend_Db_Table_Row last week and dependencies are
only triggered when you work on the Zend_Db_Table_Row of the main table.
When you call delete() or update() on the Zend_Db_Table_Row, it will call
it's associated Zend_Db_Table's cascading method which will then call the
delete() and update() on the "dependant" Zend_Db_Table, which has been
created dynamically by the Zend_Db_Table_Row of your initial table.
Bottom line, calling delete() or delete() on a Zend_Db_Table_Row will
trigger delete() and update() on a Zend_Db_Table.
If you call delete() or update() on a Zend_Db_Table, it *won't* use the
dependencies/trigger system.
