We're on Civi 4.6.9, Drupal 7.
I've installed and am using the CiviCampaign component. I like it. I've used the Canvass activity type added by CiviCampaign in a webform, created using the webform-civicrm Drupal module. Here's a screenshot of the webform CiviCRM activity field.
Now, I want to enable any user to see Canvass activities that any other user has entered using the webform.
In Civi, only the Added by: user, the Assigned To: user (if any), the "target" contact and an Admin (me) can see the Activities in the Added by: or Assigned To: user's record.
There are other users who oversee volunteer users entering Canvass activities (the Added by: user), as well as staff and volunteers conducting the canvass (the Assigned to: user) that need to be able to see all the Activities data entered in each contact's Activities list.
I can and have created Groups of the target contacts who have the relevant Canvass activity and any user can see the Contacts in the relevant Group.
I've looked here and elsewhere. I've also tweaked the CiviCampaign permissions. No luck so far.
