I'm beginning to play around more with OE and just trying to explore making a simple(so I would think) module, but I have seemed get stuck on displaying the grid(view field).

In the "Almost Complete" you can see in the grid I'm missing VALUE for the parametric

My other question, when I select "Component Type" could I get the grid(Parametrics) pre-populate with a set of Parametric Type's that are assigned to say Resistor in this example?

Here is my code:

tilparts.py:

# -*- coding: utf-8 -*-

from openerp.osv import fields, osv

class tilparts_componenttype(osv.osv): 
    _name = 'tilparts.componenttype'
    _rec_name='component_type'
    _columns = {
        'component_type': fields.char('Component Type',size=32),
    }
tilparts_componenttype() 

class tilparts_part(osv.osv):
    _name = 'tilparts.part'
    _rec_name='partno'
    _columns = {
        'partno': fields.char('Part Number',size=48),
        'componenttype_ids': fields.many2one('tilparts.componenttype','Component Type',select=True),
        'parameter_ids': fields.one2many('tilparts.parameter','parametrics_id',string='Parametrics',select=True),       
    }
tilparts_part()

class tilparts_parameter(osv.osv): 
    _name = 'tilparts.parameter'
    _rec_name='parametrics_id'
    _columns = {
        'parametrics_id': fields.many2one('tilparts.parametrics','Parametric Type', ondelete='cascade'),
        'value': fields.char('Value',size=16),
    }
tilparts_parameter() 

class tilparts_parametrics(osv.osv): 
    _name = 'tilparts.parametrics'
    _rec_name='parametric_type'
    _columns = {
        'parametric_type': fields.char('Parametric Type',size=16,required=False,ondelete='cascade'),
        'componenttype_ids': fields.many2one('tilparts.componenttype','Component Type',required=False,ondelete='cascade'),
    }
tilparts_parametrics()
