spring binding with displaytable and multi checkbox

[Julien Gribonvald]

Hello,

It makes several hours that after a problem with my multiselect checkbox
in a pagined table.

My problem is that my checkbox which are selected in one page aren't
kept when i go on a next pagined page, someone have experienced a such
thing or have exemples on how to works with a such case ?
An other problem is that when i go back to the previous pagined page i
can't obtain my next selections.

So here is my code :

                    <spring:bind path="subKey">
                                       <d:table name="${userList}"
id="user" sort="list" requestURI="${submitAudience}"
                                                    export="false"
class="dataTable" defaultsort="2" defaultorder="ascending"
                                                   
pagesize="${nbItemsToShow}"    
decorator="org.displaytag.decorator.TotalTableDecorator">

                                                    <d:column
title="Select">
                                                        <input
type="checkbox" name="subKey"
                                                           
value="${user.userId}" />
                                                    </d:column>

                                                    <c:forEach
items="${attrDisplay}" var="displayAttr">
                                                        <d:column
titleKey="news.label.${displayAttr}" sortable="true">
                                                            <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>
                                                </spring:bind>
subKey is a String[] parameter.

When I submit my selection I have also the current page selection only.

Thanks for those who can help me for this problem, i tryed many things
but without success.

Thanks

- Julien

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

Hi,

I don't know spring binding, but I think you should try and make a difference between the pagination (the submitting of the form when paginating and sorting) and the submiting using the other buttons (search, cancel) - maybe using a "DispatchAction".
One method for search and another one when paginating (making the same seach, with the initial parameters).
The form has to be submitted when pagination occurs so it can retrieve the checked checkboxes.

Cheers,
Narcis

[Julien Gribonvald]

Thanks for your response, it was something that I thougth, I have to
pass to the form the information that the user is paginating. But i
can't find documentation on how to pass attributes to the form when it's
for paginating and sorting, or if there are specials attributes which
indicates that's the user make a sort or go to next pagnined page.

Also how can I pass a such information only for paginating and sorting?
I mean how to add attributes to the form ? because I tried to make a
such thing : form="${namespace}AddAud?navigate=true" at the place of
form="${namespace}AddAud", but it doesn't pass the attribute correctly
and the form isn't more recognized...

Thanks

Julien

[Paslaru Narcis]

I usually use a hidden input with the value "paginating".
And for the other buttons (Search, Cancel, etc.) put a onclick javascript function that changes the value of the hidden to "not Paginating".

Cheers,
Narcis

Thanks for your response, it was something that I thougth, I have to pass to the form the information that the user is paginating. But i can't find documentation on how to pass attributes to the form when it's for paginating and sorting, or if there are specials attributes which indicates that's the user make a sort or go to next pagnined page.

Also how can I pass a such information only for paginating and sorting? I mean how to add attributes to the form ? because I tried to make a such thing : form="${namespace}AddAud?navigate=true" at the place of form="${namespace}AddAud", but it doesn't pass the attribute correctly and the form isn't more recognized...

Thanks

Julien

Hi,

I don't know spring binding, but I think you should try and make a difference between the pagination (the submitting of the form when paginating and sorting) and the submiting using the other buttons (search, cancel) - maybe using a "DispatchAction".
One method for search and another one when paginating (making the same seach, with the initial parameters).
The form has to be submitted when pagination occurs so it can retrieve the checked checkboxes.

Cheers,
Narcis

   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]
