GtkTreeView and GtkTreeStore problem

I've combed through the docs and can't figure this out: // get GTKTreeView listClientProjects through GladeXML first // test fill store $cpStore = new GtkTreeStore(Gtk::TYPE_STRING, Gtk::TYPE_STRING); $cpStore->append(NULL,array('Test1','1')); $cpStore->append(NULL,array('Test2','2')); $cpStore->append(NULL,array('Test3','3')); // add columns $this->listClientProjects->append_column(new GtkTreeViewColumn('Column1', new GtkCellRendererText(), 'text', 0)); $this->listClientProjects->append_column(new GtkTreeViewColumn('Column2', new GtkCellRendererText(), 'text', 0)); $this->listClientProjects->set_model($cpStore); Unfortunately, I can only get this to work if I have ONE column. Once I go to two or three columns, the FIRST item in the array is repeated for each column. This happens even if the second column and items are set to other types, or if their order is reversed. And I do have the latest phpgtk2 dll... Halp?
