    DataObject Question Link to this post

    I've gotten some strange behavior trying to put a ManyManyComplexTableField into a DataObject. When I put in the following code and try to create a new entry I just get a blank box and my PHP logs say "Call to a member function MyUnits() on a non-object in /Applications/MAMP/htdocs/ss_clean/sapphire/forms/HasManyComplexTableField.php" - but when I try to edit an existing record I get the table I want but nothing gets saved when I updated even though it says it went through.

    class Person extends DataObject {

       static $db = array(
          'FirstName' => 'Text',
          'LastName' => 'Text',
          'Role' => 'Text',
          'Email' => 'Text'

    static $has_one = array(
       'HeadShot' => 'Image',

       static $many_many = array (
          'MyUnits' => 'Unit'

       function getCMSFields_forPopup() {
          $fields = new FieldSet();

          $fields->push( new TextField( 'FirstName', 'First Name' ) );
          $fields->push( new TextField( 'LastName', 'Last Name' ) );
          $fields->push( new TextField( 'Email' ) );

          $fields->push(new DropdownField('Role', 'Role', array(
                'Alumni' => 'Alumni',
                'Faculty' => 'Faculty',
                'Staff' => 'Staff',
                'Student' =>'Student'
             )), 'Content'
          $fields->push(new ImageField('HeadShot'));
          $fields->push(new ManyManyComplexTableField(
             array('Name' => 'Unit Name')
          return $fields;


    so when I take out the "push->(new ManyMany..." I can create a new record, but when I put it back in it only shows on edit - but nothing gets saved. I'm not sure if I'm explaining this clearly as I'm honestly confused...
