Readonly ManyToMany mapping? [message #540003]

I have a many-to-many association database view and I mapped entity A and B using this association database view, the problem now is that when I need to delete A, it try to delete the association entry in the db view.. How do a map a many-to-many in a ready only fashion? Just like in manytoone we have insertable="false", etc.

Btw, I'm using XML for the mappings.

Thanks,

EclipseLink has a readOnly option on all of its mappings that can be used to avoid the delete from the join table. Unfortunately there is currently no support to enable this in annotations or xml, you need to use a DescriptorCustomizer to get the ManyToManyMapping and set it to be readOnly.

Please log a bug that readOnly is not supported from annotations and xml, and vote for the bug.
