It seems like a threading problem. In fact if I comment out the two
following lines in the apache VirtualHost file
WSGIDaemonProcess dashboard.habble.it processes=5 threads=1
display-name=%{GROUP}
WSGIProcessGroup dashboard.habble.it
I receive no longer the error, but somehow the information about the number
of forms in the FormWizard.form_list is "remembered" by apache:
I mean after completing one booking for an event with one guest (so it is 3
forms), I close the browser. Then I launch a different browser, and my app
show itself to me already with 3 steps instead of 2 as it should be!
Could it be a server caching issue?
