Hi All I have a class called shared data that extends ModelAdmin:

 class SharedData extends ModelAdmin
{
    // Managed models - Each model automatically get a tab added to Shared Data admin page
    public static $managed_models = array(        
        'EmpArea' => array('title' => 'Employment Areas'),      
    );

    public static $model_importers = array(
        'EmpArea' => 'CsvBulkLoader',
         );

    public static $url_segment = 'shared-data';

    public static $menu_title = 'Shared Data';

    // Place it right below the Pages menu item which has a priority of 10
    public static $menu_priority = 9;
} 

and a model called EmpArea:

 class EmpArea extends MultilingualDataObject {

	public static $db = array(

	    'Name' => 'Varchar'
	);


  public function getCMSFields() {
 
         $fields = parent::getCMSFields();

		    $fields->addFieldtoTab('Root.Main', new TextField('Name', 'Employment Area'));
 				// add extension updateCMSFields to include translations
        $this->doExtend("updateCMSFields",$fields, get_class());
        return $fields;
  }

} 

everything displays perfectly and the grid can be sorted with the sort ascending/descending grid headers and you can navigate to the individual models to vie/edit them. The problem arises when you filter the model with the filter widget on the left menu, any filter constraint added will return the correctly filtered items but the items can no longer be selected to view/edit them. When you attempt to navigate to a filtered model you get a vagrant error:

 ERROR [User Error]: Couldn't run query: 
SELECT DISTINCT "MultilingualDataObject"."ID"
FROM "MultilingualDataObject"
WHERE ("EmpArea"."Name" LIKE '%HR%') AND ("MultilingualDataObject"."ClassName" IN ('EmpArea'))

Unknown column 'EmpArea.Name' in 'where clause'

The URL for one of the is:

/admin/shared-data/EmpArea/EditForm/field/EmpArea/item/420/edit

After a filter is applied it changes to:

/admin/shared-data/EmpArea/EditForm/field/EmpArea/item/420/edit?q%5BName%5D=HR&action_search=Apply+Filter

If you delete the filter part out of the url the page navigates fine.
Any help or suggestions would be greatly appreciated.
