AttributeError: 'Ticket' object has no attribute 'is_writeable_field'

[lalit.bhatt@…]

I was trying to do bul update for Milestone field. Even If I select multiple tickets, it only updates one ticket at a time and throws the following error.

How to Reproduce

While doing a POST operation on /batchmodify, Trac issued an internal error.

(please provide additional details here)
