Grails: save() works, update and delete() do not work

[Kai Wähner]

Hi there,

I have the following simple integration test:

    
    public void testMitarbeiter() {

        // works
        def m1 = new Mitarbeiter(name: 'Kai')
        m1.save()

        // does not work
        def neu = Mitarbeiter.get(m1.id)
        neu.name = 'Hans'
        // neu.save() // does not work either

        // works
        def m2 = new Mitarbeiter(name: 'xxx')
        m2.save()

        // does not work
        def fromDB = Mitarbeiter.get(1) // 1 is the id of the saved instance in the database
        fromDB.delete()
    }

Mitarbeiter is also simple:

   
class Mitarbeiter {
    
    String name


    static constraints = {
        name(unique: true)
    }

}


 

The test passed without any errors. Saving some instances works, but I cannot update or delete them.

What's wrong with this code or what else could be the problem? (btw: I use the current Netbeans with Grails support as IDE).


Best regards, Kai

Try calling save(flush:true) instead of just save()

Although I am aware of the "flush"-concept in JPA, I did not find anything about it in my grails book and tutorials. Works now. Thank you...
