AttributeError: 'NoneType' object has no attribute 'set_text'

Hi,

I'm using the trunk GTK client. I have a fields.reference used in a form view. This is the form view used from a one2many double click. I added a dynamic "attrs" on this reference field to make it readonly if a boolean field is not checked.

This work fine when I double click on line in the one2many for the first time : The form view opens, and my field is readonly until I check the combobox (btw, why the combobox is not readonly too ?).

But if I close the window and double-click on the same item, then I got this error in my client console :

Then my dynamic attrs doesn't work anymore.
