I recently installed a new EtherpadLite server and migrated all of my existing pads to it. The problem is, all of the exsiting tasks in OpenERP have the link to the old EtherpadLite server.

Changing the URL in Settings->Companies->Company->Configuration only changes the URL for new tasks, I need to change all of the exisiting ones too.

How can I change the link to the new EtherPad Server in OpenERP?

I have tried to add a field for editing in the FormView of the task using the description_pad field, but that didn't work either.

Any suggestions?
