2007/6/8, David Avendasora <[EMAIL PROTECTED]>:
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?
It's exaclty the opposite... you should check the onws destination in Tool,
(see at this in the end of the page:

Thanks,
Dave
