I think it's right. In 1.8, joined fields are editable. Input values
are displayed in the attribute table, but their values are not saved
when I save the layer as a new file.
My patch[1] does not hide joined fields in new feature form, but it
makes joined fields uneditable. As soon as we create a new feature on
join layer, fields in the joined table are bind to the new feature
corresponding to the value of the target field. I believe that editing
join layer should work well with two patches[1][2].
