Ticket update fails with HTTP 500 if Agilo for Trac installed

[ps@…]

When trying to change a field from the query table, the browser issues an AJAX request like this:

​http://trac.domain.ch/trac/Project/gridmod/update?_=1350658481047&ticket=1&component=SomeComp

With Agilo 1.3.8 installed along GridModifyPlugin 0.1.5 this results in the following exception:

  File "build/bdist.linux-i686/egg/gridmod/web_ui.py", line 103, in process_request

    repr(self.get_type()))
TypeError: %d format: a number is required, not unicode  

Reason: Agilo wraps Trac's ticket/model.py and uses the ticket id in transforming it to a string. In some cases the ticket is retrieved as a unicode literal (i.e. u'1' instead of an integer, causing the above error.

Fix: Make sure the id is passed on to the ticket instance as an integer. Patch attached.

Patch to pass ticket id as integer

[Ryan J Ollos]

(In [12223]) Fixes #10506: Cast ticket ID to an int before passing to the Ticket constructor to avoid an exception with AgiloTrac. Thanks to ps@… for the patch.

The _=1350658481047 in the URL must come from Agilo, right?
