Hello!
I tried to run a basic database model through the reverse enginering tool that comes with
seam gen and I am getting a java.lang.StackOverflowError without any details.
Here is the output from running seam generate-entities (working with a configured project
that works fine when running generate-entities with other tables):

I was able to narrow it down to the use of a foreign key constraint referencing to the
same table. Here is an example:
| DROP TABLE IF EXISTS `people`;
| CREATE TABLE `people` (
| `id` bigint NOT NULL,
| `given_name` varchar(20) NOT NULL default '0',
| `name` varchar(20) NOT NULL,
| `fk_likes_person` bigint default NULL,
| PRIMARY KEY (`id`),
| FOREIGN KEY (fk_likes_person) REFERENCES people(id) ON DELETE NO ACTION
| ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
|
According to MySQL Documentation this is possible with InnoDB tables
anonymous wrote :
| ...Note that InnoDB supports foreign key references within a table. In these cases,
"child table records" really refers to dependent records within the same
table...
|
Is there a good reason for this behaviour? If you consider this as a bug, please point me
to the right place for reporting it.
