On a previous site using silverstripe 2.4 i followed a tutorial to allow team profiles to be administered in the model admin which then allowed me to go into the admin and select the profiles per page via a checkbox: http://www.balbus.tk/many-many-checkboxsetfield/

Because dataobject manager is deprecated i cant seem to replicate this in SS3.0. I can get the dataobjects to view in Model Admin but cant get the admin page to view on the relevent page to show all the profiles with checkboxes.

The code i have so far is:

<?php
class TeamProfile extends Page {

	public static $db = array(
		
		
		
		
	);

	public static $has_one = array(
	
		
		
		
	);
	
	public static $many_many = array(
        
		 'TheTeams' => 'TheTeam'
    );
	static $has_many = array(
		
		 
	);
	
	
	function getCMSFields() {
		$fields = parent::getCMSFields();
		
		$fields->removeFieldFromTab("Root.Main", 'Content');
		
		/*$fields->addFieldToTab('Root.Content.Banner', new ImageField('BannerImage','Banner Image'));*/
		
		
		
		 $gridFieldConfig = GridFieldConfig::create()->addComponents(
      new GridFieldToolbarHeader(),
      new GridFieldAddNewButton('toolbar-header-right'),
      new GridFieldSortableHeader(),
      new GridFieldDataColumns(),
      new GridFieldPaginator(10),
      new GridFieldEditButton(),
      new GridFieldDeleteAction(),
      new GridFieldDetailForm()
    );
	


    
		$config = GridFieldConfig_RelationEditor::create(); 
		$config->addComponent(new GridFieldSortableRows('SortOrder'));
            $config->addComponent(new GridFieldBulkEditingTools());
            $config->addComponent(new GridFieldBulkImageUpload());
		
			
	$theteams= DataObject::get('TheTeam');
 
        if (!empty($theteams)) {
 
            // create an array('ID'=>'Name')
            $map = $theteams->toDropdownMap('ID', 'SpecialistName');
 
            // create a Checkbox group based on the array
            $fields->addFieldToTab('Root.Content.TheTeams',
                new CheckboxSetField(
                    $boxname = "TheTeams",
                    $title = "Select Team Members",
                    $source = $map
            ));

			
			
         
			 return $fields;
			
	
		}
		
		
		

	}
	
	

}
class TeamProfile_Controller extends Page_Controller {
	
	
}

Please help, Im hoping its just a case of amending the dataobject code at the bottom
