Hi all

I am trying to create a simple testimonials page, with using the new gridfield in SS3 I am running 3.1.0 and I also have silverstripe-gridfield-betterbuttons module, my code bellow

Testimonial.php

<?php
class Testimonial extends DataObject {

	public static $db = array(
		'Name' => 'Varchar(255)',
		'Testimonial' => 'Varchar(255)'
	);
	
	public static $has_one = array(
		'TestimonialsPage' => 'TestimonialsPage' 
	);
	
	public function getCMSFields() {
	 		$fields = parent::getCMSFields();
			$fields->removeFieldFromTab("Root.Main","TestimonialsPageID");
			return $fields;		
	  }

}

TestimonialsPage.php

<?php
class TestimonialsPage extends Page {

	public static $has_many = array(
		'Testimonials' => 'Testimonial' // Link the Testimonial Items
	);
	
	public function getCMSFields() {
		$fields = parent::getCMSFields();
		
		        // Create a default configuration for the new GridField, allowing record editing
		        $config = GridFieldConfig_RecordEditor::create();
		        $config->getComponentByType('GridFieldDataColumns')->setDisplayFields(array(
		            	'Name' => 'Name',
						'Testimonial' => 'Testimonial'
		        )); 
		        // Create a gridfield to hold the student relationship    
		        $testimonialsField = new GridField(
		            'Testimonial', // Field name
		            'Testimonials', // Field title
		            $this->Testimonials(), // List of all related students
		            $config
		        );      
		        // Create a tab named "Students" and add our field to it
		        $fields->addFieldToTab('Root.Testimonials', $testimonialsField);
		        return $fields;
	}

}
class TestimonialsPage_Controller extends Page_Controller {

}

When I click save and add another button in CMS i get the below error in the CMS am I doing something wrong here? the record actually gets added also.

Warning at line 673 of /framework/forms/gridfield/GridField.php

Thanks in advance

At first glance it all seems OK, I noticed a typo on the GirdField though. Missing an 's' off Testimonials.

$testimonialsField = new GridField(
'Testimonials', // Field name
'Testimonials', // Field title
$this->Testimonials(), // List of all related students
$config
);
