I would like to know how I could modify the components and values that I want to be displayed on the page.
On the one hand, I would like to be able to edit the values of a record from the list table and save the edition.
On the other hand I would like to show in a combobox the name or description of my field "son (Fk)"
I would like to know which files are xml, jspx and/or java to take into account when editing in order to customize them.
Take a look at the gvNIX user manual and the quick-start examples , especially the sections on the Datatables component and the Lupa component.
In order to give you a more concrete answer, it is necessary to narrow the question a little more.
Luck!
