Hi guys,

So, I have a dataobject type, which is managed from the CMS. One of the page types in my site can have one or more of these dataobjects assigned.

//page class 
public static $belongs_many_many = array( 
   'DataObjectList' => 'MyDataObject', 
);

//data object 
public static $many_many = array( 
'Pages' => 'MyPage' 
);

The page type has a listboxfield with multiselect set to true and populated with all of the available dataobjects, like so:

$dropdown = new ListboxField('DataObjectList', _t('DATAOBJECTS', 'Data Objects'), DataObject::get('MyDataObject', "", 'Name DESC')->toDropDownMap()); 
$dropdown->setMultiple(true); 
$fields->addFieldToTab('Root.Content.Main', $dropdown, 'Content');

Now, this displays fine in the CMS admin, but when one or more items are selected in the admin, they don't save. What do I need to do to make this happen?

Thanks loads,
Lee

Anybody? It's driving me nuts.

Thanks,
Lee
