[Struts 2] Many-to-many form-interface

[David Canos <da...@gmail.com>]

I want to build a generic form-interface to cover a simple many-to-many
relation.
Like a Writer and Books relation where a Writer could write some books and a
book could be written by some writers.

I was thinking in a concrete Struts tag but I find nothing.

Could you show me how to solve this issue in a generic way?

Thanks in advance.

A multiple select seems to be the 'simplest thing that could possibly 
work' for this, but there are other options. For example, something like 
s:optiontransferselect [1] gives a slightly fancier way of providing the 
same thing. Another alternative would be to have an Ajax-y 'combo box' 
to select the first author/book, and an 'add another' button, or a 
select/combo that onchange added the selection to a separate list and 
reset, or...

Again, without knowing why you don't like the multi-select solution, 
it's all a little vague and hand-wavy.

Sorry Laurie.
I will try to make me clarify

I just want to build a form field that
* in a Author profile will let me select the books that a author have.
* in a Book profile will let me select the authors of the book.

It could be possible by a multiple select but I really dont like this
solution so I asked looking for a better way.

Thank u

It's a bit difficult to offer advice when the requirements are this 
vague... What do you want this form to do? Allow you to edit a book's 
authors? Allow you to edit an authors books? Some combination of both? 
(how would that work?)
