Troubleshooting view_parameters

Dear all,

thanks for the extension at first. I have some trouble with the embedded customtag in eZFlow. The installation is working fine so far, but I have some trouble with the registration form.

0. I have a multilingual installation (suppose it does not matter for the moment)

1. I have embedded an infobox as an eZFlow block, which contains the customtag *nvnewslettersubscribe* in order to include the subscription form. Everything shows

2. My settings in nvnewsletter.ini are
GroupsAllowed[]=1
GroupsSubscribe[1]=Test receiver group
StatusViewParameter=status
Which resembles group ID and group name

3. When calling the subscription form from /de prefix I get redirected to de(status)/success and receive an error

4. I have checked for nvnewslettersubscribe.tpl template. When adding {$#view_parameters|attribute(show)} I receive only
Attribute Type Value
offset integer 0
year boolean false
month boolean false
day boolean false
namefilter boolean false
so there is no $status attribute present.

As far as I understand the template the should be a value like failed/emailfailed etc. present within view_parameters. There is not attribute to read from though.

What do I do? Any hints would be very much appreciated.

Best wishes

Sebastian
