raw_id_fields popup missing

[liwee]

Hi,

My usual development server is running 1.7.x.
Downloaded 1.8.2 today and copied my existing project over to 1.8.2.

The popup for raw_id_fields seems to be missing. It was working on 1.7.x

raw_id_fields = ('cust', )

I had no trouble adding this to the tutorial:

class ChoiceAdmin(admin.ModelAdmin):
    raw_id_fields = ('question',)

We'll need more details such as steps to reproduce or a sample project we can download to see the error.

I started a new project based on the tutorial. I have attached relevant screens as well in order
9 (click on magnify glass) -> 10 (click on Customer object) -> 11

models.py

class Customer(models.Model):    
    name = models.CharField(max_length=200)
    
class Task(models.Model): 
    cust = models.ForeignKey(Customer)

admin.py

from .models import *

class TaskAdmin(admin.ModelAdmin):
    raw_id_fields = ('cust',)
    
admin.site.register(Task, TaskAdmin)
admin.site.register(Customer)

What browser? Any JavaScript errors in the console?

chrome Version 43.0.2357.81 m
attached javascript console output below

The popup works in IE 11.

Are you using any third-party apps? "grp" in the JavaScript console suggests django-grappelli to me. The string "grp" doesn't exist in the Django repo.

I see, yes, I am using django-grappelli.

Ran a few more tests on the clean project (without django-grappelli)

1. work in IE 11
2. work in chrome (incognito mode)
3. does not work in chrome (normal mode)

Since the same behaviour occurred initially when I created a clean project, it did not even occur to me that django-grappelli could be the culprit. Appreciate the advice. Thank you.
