Hibernate Error: don't flush the Session after an exception occurs

Hi all,

 

I'm having a bit of trouble with a domain class I have.

 

The code looks like this:

 

class Task {
    String code
    String title
    String description

 

    def beforeInsert = {
        code = "task-" + (Task.count() + 1)
    }
   
    static constraints = {
        title(blank: false)
        description(blank: true)
        code(nullable:true)
    }
}

 

And my test looks like this:

 

    void testCreateTask() {
        Task task = new Task(title: 'Task', description: 'This is a task').save()

 

        assertEquals("task-1", task.code)
        assertEquals("Task", task.title)
        assertEquals("This is a task", task.description)
    }

 

 

Removing the 'beforeInsert' and the corresponding assert statement doesn't result is this exception. When I also add a new line to the test case, (new Task.save(), which doesn't save because the title constraint), the test works. I'm a bit lost here! What I did experience btw, was that by setting the transactional flag to false, this exception also did not occur. So my best guess is that something went wrong during a rollback of the transaction, though I'm not sure.

 

Before making a JIRA for it, I though let's ask if I'm doing something wrong here.

 

Thanks,

 

Erik
