Hi

The problem is related to how the portal message thread works in Odoo. When you use t-call="portal.message_thread" multiple times in the same view, it only renders once because of how Odoo's chatter component is designed.

You need to ensure each chatter has a unique ID. The message thread component needs to be able to distinguish between different record threads.

Modify your code to include a unique identifier for each chatter section:

<t t-foreach="students" t-as="student">
    <t t-if="student">
        <div class="chat">
            <t t-esc="student.student_name"/>
            <div t-attf-id="discussion_thread_#{student.id}" class="mt-4">
                <t t-call="portal.message_thread">
                    <t t-set="object" t-value="student"/>
                </t>
            </div>
        </div>
    </t>
</t>

The key improvement in this version compared to your original code is the addition of the unique ID attribute (t-attf-id="discussion_thread_#{student.id}"). This creates a distinct container for each chatter with a unique identifier based on the student's ID, which helps Odoo properly initialize and render multiple chatter components on the same page.
