Problem with deleting a related object (to-many relationship)

Hi all,
I have the following relationship: Tool <-->> ToolConfiguration.
- Optionality for the "tool" relationship in ToolConfiguration is
"Mandatory"
- Optionality for the "toolConfigurations" relationship of Tool is
"Optional"
- "Owns Destination" is checked for the "toolConfigurations"
relationship of Tool
When I remove a toolConfiguration from the toMany relationship and
save, I get an error stating "Save Failed: Relationship tool must
have a Tool!"
By having the "Owns Destination" checked on the "toolConfigurations"
relationship, shouldn't removing a toolConfiguration from the
relationship automatically Delete the ToolConfiguration object? Am I
missing something fundamental?
Thanks,
Dave
