Hi ,

i have a class that look something like this.

class myclass(osv.Model):
    _name="myclass.class1"

    def _get_cur_subline_ids(self, cr, uid, ids, field_name, arg, context): {
       //i need my current active class_line id here !!!
       print context
       //expecting to get model_line_id in the context but cannot
    }

    def _srch_subline(self, cr, uid, obj, name, args, context):: {
       //i need my current active class_line id here !!!
       print context
       //expecting to get model_line_id in the context but cannot
    }      

    _columns = {
                "name" : fields.char('Desc.',help="enter your description"),
                "class_line_ids" : fields.one2many('class.line', 'class_id', 'Lines'),
                "lines_subline_ids" : fields.function(_get_cur_subline_ids,
                                         type='one2many',
                                         obj="product.product",
                                         method=True,
                                         string='Products List'
                                         fnct_search=_srch_subline),
                }
myclass()

XML for myclass

<field name="class_line_ids" nolabel="1"  context="{'model_line_id': active_id}">

My questions is , how can i get the ACTIVE id of my class_line_ids i.e. when user click on the tree view of the class_line_ids in my form and pass it to the context and then in turn to be used by either the _get_cur_subline_ids or _srch_subline function to filter the return ids of the object "product.product" dynamically ?
