I"ve set the following on the displaytag.properties for the paging.banner
attributes:
paging.banner.last=Result Pages: [<a
href="javascript:doPage(""SearchResult"", ""{1}"");">First</a>/<a
href="javascript:doPage(""SearchResult"", ""{2}"");">Prev</a>] <font
class="currentPage"> {0} </font>
Where "doPage" is a javascript method:
function doPage(fname, actionName) {
document.forms[fname].action = actionName
document.forms[fname].submit();
}
Thanks

There are two solutions: you can heavily modify the various paging
properties in TableTag.properties (well, you'd override them in your own
displaytag.properties, as described in
http://displaytag.sourceforge.net/configuration.html). Specifically,
you'd need to modify paging.banner.full, paging.banner.first, and
paging.banner.last to grab the generated URL and modify it to submit the
form along with the paging (and any ordering) parameters along with the
checkboxes. Sounds like kind of a nightmare to me.
The second solution is just to NOT do what you're suggesting. As a
general interface rule, you probably shouldn't have this kind of
functionality. Suppose I go to the first page of the data set, select a
couple of items, then go to the next page, select a couple of items, and
so on. Five or six pages into it, what have I selected? I can't really
tell without going backwards, which is both inconvenient for the user and
provides you with another data management task restoring the checkboxes of
the selected items.
I'd suggest instead having some sort of way of selecting items on each
page, then adding them to a list that is also displayed. Something like
this:
Things Selected Things
[ ] Item 1
[ ] Item 2
[ ] Item 3 Add->
[ ] Item 4
[ ] Item 5
Next->
So the user selects Item 2 and Item 4, then clicks Add. It now appears
like this:
Things Selected Things
[ ] Item 1 Item 2
[*] Item 2 Item 4
[ ] Item 3 Add->
[*] Item 4
[ ] Item 5
Next->
Now click Next and it looks like this:
Things Selected Things
[ ] Item 6 Item 2
[ ] Item 7 Item 4
[ ] Item 8 Add->
[ ] Item 9
[ ] Item 10
<-Prev Next->
Select a couple here, they're added to Selected Things, keep paging
around, etc. Then, when the user clicks OK or Submit or whatever, only
the list of Selected Things is submitted to the final operation.
This addresses both the interface issues with your problem and trying to
make the Prev and Next clicks serve dual purposes.
