using the Image crooper with DialogFragment

Hi.
I am trying to use the CropImageView object in a DialogFragment. My fragment is built in a way that I can use it as a fragment or as a DialogFragment. when I use it as a fragment it works ok. but when I am trying to use it as a DialogFragment the CropImageView won't show the selected image.
is the CropImageView can work with dialogFragment?
how can I implement it in a DialogFragment?

Thanks
Ben

**this is the fragment:**
```

// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
