Requery form data block is empty after updating notification attributes

Question

Hello,
we build a form to approve/reject open WF notifications.
The form data block is based on wf_notifications,
wf_local_user_roles, wf_notification_attributes and wf_comments and some additional PSB tables.
We use the following API's to perform the update:
wf_notification.SetAttrText( nid => l_notification_id
, aname => 'RESULT'
, avalue => l_result);
wf_notification.respond(nid => l_notification_id
,responder => name_in('FORM_GLOBALS.USER_NAME')
,respond_comment => name_in('FORM_GLOBALS.REDEN_AFWIJZING') );
First the query shows 3 notifications and after updating one notification as shown above a requery is performed on the datablock and no records are shown anymore.
If I remove the code wf_notification.SetAttrText then the 2 remaining notifications are shown.
It looks like the wf_notification.SetAttrText is conflicting with my view.
This is my view:

Hi Mat,
the attribute is only set for those notifications which are selected in the form.
l_notification_id is filled with the notification_id of the selected record.
This is the piece of code within the process loop:
l_notification_id := name_in('WERKLIJST.NOTIFICATION_ID');
l_result := name_in('FORM_GLOBALS.NOTIFICATION_ACTION');
wf_notification.SetAttrText( nid => l_notification_id
, aname => 'RESULT'
, avalue => l_result);
wf_notification.respond(nid => l_notification_id
,responder => name_in('FORM_GLOBALS.USER_NAME')
,respond_comment => name_in('FORM_GLOBALS.REDEN_AFWIJZING')
