On my webform, I enabled 2 contacts. Contact 1 has 'Existing user' enabled and set to 'static' and default value is 'current user'. Contact 2 has 'Existing user' enabled and set to 'drop down' and default value is 'relationship to contact 1' relationship = 'child of'.
My goal is that contact 1 can go to that form and select one of his children and fill out the form. The form doesn't respect the filter and displays all civicrm contacts in the drop down menu.
I also tried setting default values to use filters and set the filter to contact type to= campers, I also enabled the 'Enforce Permissions'. The drop down still displays all civicrm contacts for contact 1 even though he only has permissions to edit his/her child.
