Crisis averted :)
The last line above is my problem. Removing it allows the signal to fire. I'm
not sure why, though. Also the timing of the signal differs for the upper and
lower views in that the signal for the upper view fires before the toggle is
actually performed and so one must perform the (vetted) assignment to the model
column in the slot callback. The slot for the lower view, however, is called
only once the toggling and model-edit has already been done.
Is there a reason for this difference?
Kind regards,
Edd
