Currently,I am working on a project where I have came across a requirement which I will explain below.

I have a form view in which there is one Many2One field(It is parent class) and one One2Many Field(It is child class).On the basis of selection of values from this Many2One Field,I am populating values in One2Many fields(In fact,I am appending values to One2Many).Now there are four character fields(the values will come from one2many) in the same form(In Parent Class).

The purpose of this four character fields is used to show the values from One2Many Field.Now when i am clicking on a single record in One2Many,my aim is to populate values in these four character fields.I have tried number of ways but no success so far.Please suggest me solution.
