[struts 2] Table question
by Milan Milanovic
::
Rate this Message:
Hi,
first I'll ask again my earlier question, is there possibility to show in a combo box two values, for example I want to show id and name of the every fruit: 1 Apple ? The second question is, my struts 2 application on one jsp page will have 5 combo boxes, 4 text boxes, two buttons and two datetime pickers, and below all these controls a table that will show what is entered using controls above. The problem is that my table will have about 100-120 records (rows) to show, and I think that is very much for one jsp page, and also I want user to see about last 10 rows, because he need to see if there is any error. How can I do this, can I use table pagination (how) ? -- Thx in advance, Milan Milanovic |

I have to admit that in your first instance I would cheat -- I would dummy
up a method somewhere on my action class or my POJO that returned the desired string, rather than trying to compose the string within the JSP. I am unfamiliar with the various tags that can be used to display chunks of a table. I know they're out there (the display tag library comes to mind). The most recent time I had to do this I rolled my own; it was pretty painless. I held the data in a List of data objects, and then used List.subList() in my action method to determine the precise chunk of the List that I wanted to show. Hope this helps. jk On Tue, May 13, 2008 at 9:30 AM, Milan Milanovic <milanmilanovich@...> wrote: > Hi, > first I'll ask again my earlier question, is there possibility to show in > a combo box > two values, for example I want to show id and name of the every fruit: 1 > Apple ? > The second question is, my struts 2 application on one jsp page will have > 5 combo > boxes, 4 text boxes, two buttons and two datetime pickers, and below all > these controls a table > that will show what is entered using controls above.

Hi!
To have a composed string you can do it in JSP. Something like: <s:select list='fruit' listKey='fruit_id' listValue="${fruit_id} ${fruit_name}" /> for example. And, for pagination, try displayTag, its easy to use Felipe A.

Except you can't use EL expressions in struts tags in the latest versions of
