Installing the module website_livechat in a database with demodata works, but with an empty database this message appears when I try to install the module (im_chat and im_livechat already installed and working fine):
File "/opt/odoo/odoo-server/openerp/addons/base/ir/ir_model.py", line 884, in xmlid_lookup raise ValueError('External ID not found in the system: %s' % (xmlid)) ParseError: "External ID not found in the system: im_livechat.channel_website" while parsing /opt/odoo/odoo-server/addons/website_livechat/website_livechat_data.xml:5, near <record id="website.default_website" model="website"> <field name="channel_id" ref="im_livechat.channel_website"/> </record>
