Introduction

The plone.app.lockingbehavior package provides a plone.locking integration for dexterity.

Usage

Just use the behavior plone.app.lockingbehavior.behaviors.ILocking in your dexterity content type. Also check the condition of the "edit" action of your type, it should check if the object is locked.

In your profiles/default/types/YOURTYPE.xml add the behavior and the edit action:

<?xml version="1.0"?>
<object name="example.conference.presenter" meta_type="Dexterity FTI"
        i18n:domain="example.conference" xmlns:i18n="http://xml.zope.org/namespaces/i18n">

    <!-- enabled behaviors -->
    <property name="behaviors">
        <element value="plone.app.lockingbehavior.behaviors.ILocking" />
    </property>

    <action action_id="edit"
            visible="True"
            title="Edit"
            category="object"
            url_expr="string:${object_url}/edit"
            condition_expr="not:object/@@plone_lock_info/is_locked_for_current_user|python:True">
        <permission value="Modify portal content"/>
    </action>

</object>

The ILocking behavior enables locking support for your content type. This adds the ITTWLockable interface from plone.locking. The locking viewlet from plone.app.layout is also working for the dexterity content type.
