Hi, i'm trying to put a chatter in a custom module.. here is my code :

.py :

from odoo import models, fields, api
from dateutil.relativedelta import relativedelta
from odoo.exceptions import ValidationError

class Warranty(models.Model):    
_name = 'eb.warranty'    
_description = 'Warranty'    
_inherit = ['mail.thread']

.xml :

	​</sheet>
	​​<div class="oe_chatter">
	​	​​<field name="message_follower_ids" widget="mail_followers"/>
	​	​<field name="message_ids" widget="mail_thread"/>
	​</div>
</form>

​The chatter is appearing but in a strange format... did you guys already have this issue?

It appears like this at bottom of the view... like there are the fields but no formatting.. Thanks in advance for your help
