Admin errorlist not shown in case of validation error

[esistgut]

Relevant snippet from the model:

class Language(models.Model):
    driver = models.ForeignKey('Driver')
    data = hstore.DictionaryField()

    objects = hstore.HStoreManager()

class Driver(models.Model):
    name = models.CharField(max_length=255)
    surname = models.CharField(max_length=255)

relevant part from the admin:

class LangInline(admin.StackedInline):
    max_num = 1
    extra = 1
    model = models.Language

admin.site.register(models.Driver, inlines=(LangInline,))

If I try to save a new driver without adding any row to the "data" field it fails saying "Please correct the error below." but no error is printed.
If I add a row to the field the Driver and Language models are created but then If I try to remove the Language model from the Driver's admin page I get the message "Please correct the error below." again.

If I set a default value for the field

data = hstore.DictionaryField(default={})

it works as I expect.
Is this the correct way? Am I missing something?

could you debug with the javascript console and see what is sent to the server?

Are you using the default admin template? With which version of django?

hey @esistgut could you answer my questions?

Hi, sorry for the late answer. I can't help you with the actual debugging anymore because we are no longer using hstore and we dropped django-hstore out of our dependencies.
I was using the latest stable release (1.6.x) with the default admin template.
