[jira] Created: (CAY-1520) Deleting Objects with Flattened
Read-Only Relationships
Deleting Objects with Flattened Read-Only Relationships
-------------------------------------------------------

URL: https://issues.apache.org/jira/browse/CAY-1520
Project: Cayenne
Issue Type: Bug
Affects Versions: 3.0.1
Environment: multiple

When deleting an object with a flattened read-only relationship an exception is thrown:

It might be the same issue as CAY-784, but I haven't looked at the code yet.

[jira] Commented: (CAY-1520) Deleting Objects with Flattened
Read-Only Relationships

Andrus Adamchik commented on CAY-1520:
--------------------------------------
Good to know that you found a workaround. Runtime relationships (those relationships created implicitly by Cayenne to avoid forcing users to create them), are causing quite a bit of trouble in a number of mapping scenarios. So here we have another one.

[jira] Closed: (CAY-1520) Deleting Objects with Flattened Read-Only
Relationships
Posted by "Jan Schaumlöffel (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CAY-1520?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jan Schaumlöffel closed CAY-1520.
---------------------------------
Resolution: Invalid
Can work around this after inspecting the code, it is not really an issue anyway.
The documentation recommends setting the delete rule to something different from the default "no action" and states that "nullify" does not do anything if there is no reverse relationship. Setting anything but "no action" for a read-only relationship causes this issue.
Might be a good idea to disallow anything but "no action" for read-only relationships in the modeler.
