Hi guys,

Ok i'm using version 3.1 beta 3 and am trying to display the value of a boolean and also of a date field 'Nice' in a model admin page. I used to use the code below to do this but now i get 'unable to transverse' errors, any pointers?

public static $summary_fields = array(
   		'NiceShow' => 'Show Live'
		
	);

public function getNiceShow() { 
		return $this->obj('Visible')->Nice(); 
	}

Cheers

Mick

Could you paste in the actual error and error backtrace?

Try setting private static $searchable_fields = array();. It may have been fixed before beta3, but there was previously a bug which meant that $summary_fields wouldn't work without $searchable_fields being defined.
