------------------------+---------------------------------------------------
 When selecting a feature with attributes of type double and value 0.0, the
 attributes values are displayed as empty strings.

 In GetPropertyValueFromFeatReader in layers/MapGuide/php/Utilities.php,
 the value is set to "" if equal to null:
 {{{
     if ( null == $val ) {
       $val = "";
     }
 }}}

 However, the following is true/truthy in PHP:
 {{{
     ( null == 0.0 )
 }}}

 The check should probably be done with the identity/type equality
 operator:
 {{{
     if ( null === $val ) {
       $val = "";
     }
 }}}
