PluginIssue (AgiloForScrum).

[Felix Schwarz]

Looks like the batch modification plugin is not compatible with Agilo. Please ask the author to use agilo.ticket.model.AgiloTicket instead of trac.model.ticket.Ticket when Agilo is loaded.

As a workaround you might want to try Agilo's CSV interface.

Hi,

I have the same problem, so I modified the plugin to be compatible with Agilo. Here is the patch:

8c8,11
< from trac.ticket import TicketSystem, Ticket
---
> #from trac.ticket import TicketSystem, Ticket
> from agilo.ticket.api import AgiloTicketSystem
> from agilo.ticket.model import AgiloTicket
>
69c72
<         for field in TicketSystem(self.env).get_ticket_fields():
---
>         for field in AgiloTicketSystem(self.env).get_ticket_fields():
83c86
<                 t = Ticket(self.env, int(id))
---
>                 t = AgiloTicket(self.env, int(id))
152c155
<         ticketSystem = TicketSystem(self.env)
---
>         ticketSystem = AgiloTicketSystem(self.env)

I forgot to mention the patch is for the web_iu.py of the BatchModifyPlugin.
