Hi Márcio,
First, check that the sort and pagination links rendered in the HTML
appear valid. I have seen cases where the URL is corrupt because it
includes the original request parameters, resulting in the action being
invoked with an unexpected result.
They should look like:
http://foo.bar.com/context/requestUri?sort=name&dir=asc&originalParameters=originalValues.
The next issue is that displaytag uses default links that cause a
complete page reload. By "got lost", I presume you mean you clicked on
the sort link and the resulting page did not show the current tag. This
is a complication of using complex widgets in html. The only
work-around with displaytag is to ensure all state about the page layout
(such as which tab is visible) is available as a request param or read
from a cookie on a reload so that when the page is redrawn with the
correct tab and content displayed.
Finally, an approach to avoid that issue is use an ajax table widget.
That is, one that can refresh it's data without performing a full page
reload. The AjaxTags library includes a direct implementation of the
displaytag table (ajax:displaytag) [1]. I've never used it. As you're
using Dojo tabs you may like to consider Dojo's datagrid as well. I use
YUI's version.

Hope that helps!

Hi All!
This is my first e-mail.
My name is Márcio Gurgel, I'm from Brasília (Brazil). My english isn't very
well, I hope you understand (:
There's 10 months that I'm working with J2EE.
I'll finish my graduation this semester, than I'm developing a final project
using Struts 2.
So, I have a question.. Hope you can help me.
My aplication uses displayTag for list rendering.
To make search's I use two tabs (Criteria and Results).
My problem is on the tab Results when it has paging.
When I click in the pagination, it just got lost.
I tried do resolve this doing:
1 - Seting requestURI="" to call the action that returns the jsp with my
tabbed panel.
This way, returns the tab of Criteria selected (I want the Results tab).
2 - Seting requestURI="" to call the action that returns the jsp with my
list (inside the Results tab).
This way my list opens in another frame.
Here's my code (I changed the Labels to english)
I atached a screen, as I sayd I dont trust in my english...
