When you create a tree you can't use <group> and <footer> tags, please remove these and and try:

<record id="project_part_view_tree_wizz" model="ir.ui.view">
    <field name="name">Project Part List</field>
    <field name="model">project.part</field>
    <field name="arch" type="xml">
    <tree string="Parts" editable="bottom">
        <field name="project_id"/>
        <field name="number" />
        <field name="object"/>
        <field name="stage_id"/>
        <field name="part_template_id"/>
        <field name="name"/>
        <field name="user_id"/>
        <button name="generate_project_part" string="Generate"
                                type="object" class="oe_highlight"/>
        <button string="Cancel" class="oe_link"
                                special="cancel"/>
    </tree>
</field>
</record>
