I have created several dataobjects that ia wish users to edit from the front end. I can get the ComplexTableField to display the list of DataObjects associated with the user's account, however I can not get the front end forms to allow adding and editing. Any Thoughts?

Controller

    public function libraryDocuments()
    {
        $fdo = new ComplexTableField(
            $this, 
            'MyDocs',
            'LibarayItem',
            '',
            'CustomCMSFields_forPopup'
        );
        $fdo->setParentClass(false);
        
        $fields = new FieldSet(array(
            new HiddenField('ID', ''),
            $fdo,
        ));
        
        $actions = new FieldSet(array(
            new FormAction ('saveLibraryDocs','Save'),
        ));
        
       //$actions = new FieldSet(); 
        
        return new Form($this, 'libraryDocuments', $fields, $actions);
    }

Off the top of my head, I'd say the Page_Controller doesn't have access to those controllers. I know I've used ComplexTableFields in the front end, but I've always removed those functions. Have you tried specifically setting the permissions?

I was able to get this working, it was a simple permissions issue on the dataobject. I neeted to implment PermissionsProvider and add the can(?) Access to the dataobject in question.
