this. appreciated.
ok solved issue. have no clue why particular bit of code causing problem though.
in urls.py, had added following 4 url expressions...
from django.conf.urls import url, include import views
urlpatterns = [ ... #meeting urls url(r'^record_meeting/(?p<meeting_id>[0-9]+)/',views.editmeetingview.as_view(),{'record':true}), url(r'^record_meeting/$',views.editmeetingview.as_view(),{'record':true}), url(r'^edit_meeting/(?p<meeting_id>[0-9]+)/',views.editmeetingview.as_view(),{'record':false}), url(r'^add_meeting/$',views.editmeetingview.as_view()), ] the fourth 1 url(r'^add_meeting/$',views.editmeetingview.as_view(),{'record':false}), apparently, based on trial , error, causing issue. after removing additional arguments, problem went away. know why issue in first place? still don't understand.
