wizard.interface is not working in OpenERP 6.1 and 7.0 version

You should manually convert wizard.interface in to osv.osv_memory wizard,

Convert wizard.interface class into osv.TransientModel class:

class wizard_class(wizard.interface):

Convert it like this:

class wizard_class(osv.TransientModel):

and write _columns and methods inside this class.

Convert views from py to xml:

your.py

my_form = <?xml version="1.0"?>
<form string="Category Summary">
    <group colspan="4">
        <button name="check" type="object"/>
    </group>
</form>

Create view and action for your memory wizard.

your_view.xml 

       <record model="ir.ui.view" id="view_your_object_form">
            <field name="name">your.object.form</field>
            <field name="model">your.object</field>
            <field name="arch" type="xml">
                <form string="Your Text" version="7.0">
                    <footer>
                        <button string="Your Text" name="your_method" type="object" class="oe_highlight"/>
                        or
                        <button string="Cancel" class="oe_link" special="cancel"/>
                    </footer>
                </form>
            </field>
        </record>

If there is any methods, put them inside the class.

Understand the flow first then remove following code from interface py:

states = {
    'init': {
        'actions': [],
        'result': {'type':'form', 'arch':my_form, 'fields':my_fields, 'state':[
            ('end','Cancel'), ('check','Print')]}
    },
    'check': {
        'actions': [],
        'result': {'type':'print', 'report': 'report_name',  'state':'end'}
    },
}

Here ('check','Print') is called from <button="check" which then call given report.

This are not standard steps. I following this steps for convert wizard,interface into osv.TransientModel.

See following Links,

Creating Wizard - (The Process) in 6.1

Need to convert old wizard.interface to osv.osv_memory wizard

Can't install any community module on openerp v7 "Import Error: No module named wizard"

same error will be displayed ..(i make change in py file and update the module list before installation.)

Ghanshyam Prajapati

you should also make xml file. and add it __openerp__.py as per describe in my answer. after that update your module. In your loan module if that wizard is not important for you, then you can skip that wizard from wizard/__init_.py and __openerp__.py.
