I'm tryng to write into my db in uppercase. I've used the on change method in this way:

# -*- encoding: utf-8 -*-
from openerp import models, fields

class mymodule_tbl(models.Model):
        _name = 'tbl
        _description = 'Insert into my db'
        
        sdescription = fields.Text('Description', required=True)

        def uppercase(self, cr, uid, ids, sdescription, context=None):
            result = {'value': {'sdescription': str(sdescription).upper()}}
            return result 

<?xml version="1.0" encoding="utf-8"?>
<openerp>
	<data>
	
		<record id="view_mymodule_tbl_search" model="ir.ui.view">
			<field name="name">MyModule</field>
			<field name="model">tbl/field>
			<field name="arch" type="xml">
				<search>
					<field name="sdescription"/>
				</search>
			</field>
		</record>
		
		<record id="view_mymodule_tbl_tree" model="ir.ui.view"> 
		    <field name="name">mymodule_tbl.tree.view</field>
		    <field name="model">tbl/field>
		    <field name="arch" type="xml">
		        <tree string="MyModule" export="false">
				<field name="sdescription" on_change="uppercase(sdescription)"/>	
		        </tree>
		    </field>
		</record>
		
		<record id="view_mymodule_tbl_form" model="ir.ui.view">
		    <field name="name">mymodule_tbl.form.view</field>
		    <field name="model">tb</field>
		    <field name="arch" type="xml">
		        <form string="mymodule tbl" duplicate="false">
		            <group>
				<field name="sdescription" on_change="uppercase(sdescription)"/>
		            </group>
		        </form>
		    </field>
		</record>
		 		
		<record id="action_mymodule_tbl" model="ir.actions.act_window">
		    <field name="name">Tbl</field> 
		    <field name="res_model">tbl/field> 
		    <field name="view_type">form</field>
		    <field name="view_mode">tree,form</field> 
		    <field name="search_view_id" eval="False"/> 
		    <field name="context">{}</field>
		</record>
		
		<menuitem action="action_mymodule_tbl" id="menu_action_mymodule_tbl" parent="mail.mail_feeds" sequence="70"/>

</data>
</openerp> 

but it doesn't work. Any idea?

Thanks!
