problems with _inherits

[Husen Daudi]

1> If we have _inherits for some object and we have parent_id field in main object, domain like [('parent_id','child_of',ids)] not working.
2> If we use many2one for _inherits object it is not displaying name field. we are getting id of the object.

Example:
We have project _inherits from analytic account.
in analytic account parent_id field is there and on project when I search with domain [('parent_id','child_of',ids)] it is returning blank list. it should return ids at least as per child_of functionality.

one more problem
_inherits={object, field_name}

when we search on object with field_name its not working with search method.
we have to write sql query to search on it.
