openerp custom module on mobile
===

I am making a custom module in OpenERP. I have a list(tree) view and a form view. I can view and edit records. 
When I take the mobile view of the same module, I can see the main menu and browse to the sub menu, but no list view or form view is visible. All I can see is a blank page. Is my list definition worng?

`

    <?xml version="1.0"?>    
    <tree string = "Camera">    
    <field name = "a"/>    
    <field name = "b"/>    
    </tree>

Thanks in advance
