    ManyManyComplexTableField produced field list is ambiguous error Link to this post

    Hi folks,

    I have got a wierd issue with a many_many relation. I have 2 Pages a ProjectHolder and a ServicePage. The ProjectHolder page has many_many relation the ServicePage. When I add the field to the CMSFields it will come up with a nice annoying error.

    ...... CASE WHEN "SiteTree"."ClassName" IS NOT NULL THEN "SiteTree"."ClassName" ELSE 'SiteTree' END ORDER BY "Sort" LIMIT 10 OFFSET 0 Column 'ProjectHolderID' in field list is ambiguous

    here is my Projectholder

    class ProjectHolder extends Page {
       public static $many_many = array(
       function getCMSFields() {
          $fields = parent::getCMSFields();
          $tablefield = new ManyManyComplexTableField(
       return $fields;

    and here is my ServicePage

    class ServicePage extends Page {
       static $belongs_many_many = array(
    'ProjectHolders' => 'ProjectHolder'

    Does anyone have an idea as to what the issue could be ? Thx
