A common issue in portals occurs when you have a JSR-168 portlet running inside one. If you have one, you may need to change the cookie name used to maintain state from JSESSIONID (the default) to something else so the main portal web app and the JSR-168 portal web-app don't destroy each other's state every request. I am not sure if this is your issue or not.

 Gotcha; I can't really speak to any of the BEA stuff, but I'd
suggest making sure that the data set that you're binding to on the
second page has the data that you'd expect contained inside of it.
Some debug statements in the JSP (scriptlet, EL, etc) should help with
that.  If you've got any further details (stack trace, pager URL,
etc), feel free to pass them along to the list.  Also, make sure that
the configurePager's pageAction attribute is set correctly -- if it's
unset, it will just return to the JSP; otherwise, it can point to a
Page Flow action.

Hi Eddie,

Like I explained, pagination doesn't work. Only the first page is
displayed correctly. It displays X items on the page, and explains that 
it is displaying X items out of TOTAL. The links "next"/"last" seem
actives. But when I click on any of them, the grid is emptied. Like if 
the session was lost.

The case with BEA support was opened since January the 3rd, and I
finally got on Monday a CR. The backline engineer explained that he
reproduced the issue.

FYI, it happens with Workshop (10.0.1)/Portal 10 MP 1. So it is not
necessarily related to the latest version of Beehive.

I also expected the basics to work....   :)

There are several samples of paging a data grid that are included with 
NetUI, so I'd expect the basics to work.  :)  What's the specific
problem that you're having?

My issue is that clicking on "next/last" doesn't work. Only the first page is displayed correctly. After that I cannot paginate. That is wah 


the CR.

You're absolutely right: even if pagination was working, the tag
wouldn't keep track of information submitted in previous pages.

Best regards,

Philippe

Dino / Philippe--

 The data grid doesn't provide a mechanism to store state from
multiple grid views into either page flow scope or session scope.  A
single HTML page submit works by POSTing data back to the server for

the "current"

page, but without custom application logic, the grid isn't tracking
any data that was submitted from previous pages, though this would be 
a nice feature to have.

 It should be possible to do something like this by writing
UI-specific application logic that tracks all of the checked
checkboxes submitted from the data grid and then processing them when 
"Submit Orders" is clicked.  A good way to do this with Page Flow
would be to have the action submitted by the HTML form update a Page
Flow-scoped data structure that tracks an identifier for each row that 


was checked.  Just be sure that this identifier is unique and stable
-- a primary key of some sort on the record would work probably work
better than the row index which can change if the grid is sorted /

etc.

Also, be sure to add logic to checkbox rendering to correctly check
the box if a row has already been selected.

 Hope that helps.

Eddie

Hi Dino,

Got the same issue in Portal. I opened a case with BEA support and
got



a CR yesterday. FYI many customers are having the same issue.
It looks like the tag simply looses the session information somehow.

Subject: Datagrid Question

Greetings.

I have a question in regards to netui datagrid. I was wondering if
you



can help. I have attached an image and a jsp for your reference. I
am using Beehive 1.0.1 on BEA Workshop Studio.

I have a situation where a user is able to select a checkbox under
the



Buy column which selects the particular record to process in a
particular page of a datagrid. However, the user should be able to
select multiple rows from multiple pages in the datagrid by clicking 


the "Next" link to go to the next page. Clicking on Submit Orders
should process all records selected.

I am able to process the selected records from a single page when
the user clicks on Submit Orders. However, I don't know how to keep
track of selected records from multiple pages when the user clicks
on the

"Next"

link to go to the next page. The user is essentially selecting
records
from multiple pages. Of course the user should be able to submit all 


orders selected from multiple pages.

The <netuidata:renderPager> renders the "Page 1 of of 6 Previous

Next".

I believe using an anchor to submit the form content is possible
using



javascript. Processing the selected records from a single page when
the user clicks on Submit Orders does use a form submission and

works.


Any help is greatly appreciated.

Thanks so much for your time.
