Hi,
Nobody can help me ? I will try a better explaination ! (sorry for my
english)
I'm facing to some problems with displaytag lib and with pagination and
ordering options of datatable.
My problem is that i have a search result where the user can select
multi results on pagined and sorted pages if he wants, and the problem
is when the user make a sort or go on an other page, he loose his
selection.
On the doc of displaytag and with the exemples it says that i need to
set the form option in <display:table ... form="...."> to save the
selection better sorts and pages. I'm trying to do that, but it doesn't
work and it's submiting the form each time that the user make a sort or
go to next pagnied page ( I have a validator which return an error about
selected values, validator called after submit normaly)... when i remove
the form i can navigate on all pagined pages and i can make all sorts,
but with the form I stay on the first page and i can't make any sort.
Also with the form option the buttons (next, previous, cancel...)
doesn't works correctly
It make some days that I'm trying to solve that but without success, any
help would be appreciate.
Else here is a part of my form :
[CODE]
<spring:nestedPath
path="subForm">
<portlet:actionURL var="submitAudience">
<portlet:param name="action" value="addAudience" />
<portlet:param name="_page" value="${page}" />
</portlet:actionURL>
<form name="${namespace}AddAud" method="post"
action="${submitAudience }">
....
<spring:bind path="subKey">
<table border=0 cellpadding=5 width="90%">
<tr>
<td><d:table name="${userList}" id="user" sort="list"
requestURI="${submitAudience}" form="${namespace}AddAud"
export="false" class="dataTable" defaultsort="2"
defaultorder="ascending" cellspacing="1"
pagesize="${nbItemsToShow}"
decorator="org.displaytag.decorator.TotalTableDecorator">
<d:column title="Select">
<input type="checkbox" name="${status.expression}"
value="${user.userId}" />
</d:column>
<c:forEach items="${attrDisplay}" var="displayAttr">
<d:column titleKey="news.label.${displayAttr}"
sortable="true" headerClass="sortable">
<c:forEach items="${user.attributes[displayAttr]}"
var="attrValue">
<c:out value="${attrValue}" />
</c:forEach>
</d:column>
</c:forEach>
<d:setProperty name="paging.banner.item_name"
value="${tit}" />
<d:setProperty name="paging.banner.items_name"
value="${tit}s" />
</d:table></td>
</tr>
<tr>
<td><span
class="portlet-msg-error">${status.errorMessage}</span></td>
</tr>
</table>
</spring:bind>[/CODE]
Subkey is a table of string a property of subForm.
and here is my controller :
