Digging bit more, taking out the
<div class="incidentType">
{{ new_incident_form.type.errors }}
<label for="id_incidenttype">Type of Incident:</label>
{{ new_incident_form.type }}
</div>
fixes the error. However removing the same for reportType while keeping the
incidentType in place does not seem to help. This may indicate that the form
is *not* getting confused because both report and incident have a type
attribute. It seems there is an inherent problem with the incident type
itself.
Also if it helps, I am using the following to generate the html form
return render_to_response('index.html', {'latest_incidentreporter_list':
latest_incidentreporter_list, 'new_report_form':rform,
'new_incident_form':iform,'username':username})
so basically passing to form structures to the HTML page and then trying to
show new_report_form.type and new_incident_form.type
and that is where I run into issues.
