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

[anonymous]

With "timeandestimating with permissions" plugin there is an error each time I try to access to one ticket or list the timeline:

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

This is the python traceback:

Which version of trac are you using? In my trac '0.11stable-r7510' I have the 'get_value_or_default' function available.

If you have IPython installed you might try running the following commands to find out the version number and which functions are available on your version of ticket.

import trac
from trac.env import Environment
from trac.ticket import Ticket

trac.__version__ # this will tell you the version number

e = Environment('/path/to/trac/dir')
t = Ticket(e, 1)

dir(t) # should tell you which items are available

Assuming that this works since I have had no feedback
