TypeError: 'NoneType' object is not iterable when check box is selected for single entry

[themadengin33r]

When deleting volumes from dashboard by checking the "check box" on the left side it returns "something went wrong" error..

This will not show if we dont select check box and delete each volume independently.Requests is not coming to cinder-volume so i suspect its an issue with dashboard.

platform:
icehouse,centos 6.6

Reproducible: yes
Select check box before deleting volume (single volume,haven't tried with multiple volumes)

[bk160f (bk160f)]

We are getting the same Type Erorr at /project/volumes when we try to delete a Volume.

But interesting point to highlight is, this issue is not seen when we tried with Safari browser. This issue apperas when we use any otehr browser (Chrome, Firefox, IE,etc)

Can anybody answer how this is related to browser intelligence.
