RES: Paging a collection property
Sorry if I didn't explain the problem better. The pagination itself is ok (I've built a taglib that's equivalent to the one you pointed me). My question is how I can bind the input fields generated by the html and/or nested tags to the underlying objects so that any change the user makes to the input fields will be reflected on the properties of the corresponding books (to use the same example from the original message). Say the user is on page 2 and each page has 10 books. He changes the title of the first book of the page and submits the form. I want to know if struts will be smart enough to update the title of the 11th book and not the 1st book of the collection of books of the author. If so, what do I have to do to accomplish that?

The problem (or question) is: what if the number of books gets too big and I want to split these books into pages (and have a navigator for those pages), but they still belong to the same form bean, so no matter which page the user is, the nested tags (nested:text, for example) will know the correct index of the objects we're talking about (if we're on page 2 and each page has 10 books, the nested tags will start getting the objects from index 9 and not 0, and so on) and properly populates the input fields and updates the corresponding objects when loading and submiting the form respectively. I know how to do it directly with pure html code, but I'd like to know if it would be possible to get some advantage on using struts for this matter. I hope I could make myself clear.

Re: RES: Paging a collection property
Struts is very smart about multi row update (and tag uses indexed tag). But I have no idea how YOUR tag works, as far is iterator, is per page or over the collection. .V Jorge Mascena wrote: Sorry if I didn't explain the problem better.

RES: RES: Paging a collection property
I figured it out. I was missing that you can iterate just a portion of a collection with nested:iterate (i.e., you can specify offset and length). This was the missing link. Thanks anyway.
