I'm looking at view_order_form in sale/sale_view. 

It has a form with an editable tree, but when I click on any of the fields, instead of allowing to edit inline, it opens a form. 

I'm trying to do the same with no luck.

I have the form with the tree, and can edit the rows inline. I want to change this behavior to open a window with a form, as view_order_form does.

Thanks
