dataGrid PF 2.0.3

Hi. I have a problem with dataGrid.
When pagination is used, the properties values are not set correctly.
For example:

Code: Select all

<h:inputHidden id="id" value="#{userHomeBean.id}"/>

            <p:dataGrid var="item" value="#{userHomeBean.activeAnimalList}" columns="3" rows="12" paginator="true" effect="true"
            paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
            rowsPerPageTemplate="9,12,15">

                <p:column>
                    <p:panel>
                        <h:graphicImage url="#{request.contextPath}/IMServlet?id=#{item.imageUrl}" width="#{userHomeBean.user.config.widthX}" height="#{userHomeBean.user.config.widthY}"/>
                    </p:panel>
                </p:column>
            </p:dataGrid>

While first GET, page is displayed properly. When pagination button is clicked, setId() is not executed.
FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap() - contains <"id","test"> - pair, but setId is not executed.

Is it my problem, or bug in PrimeFaces?

It is a design decision, a pagination request should not process or know about other components on page, assume there are input fields with validation turned on. If these are processed similarly to your hiddeninput, these validations will be processed and when failed, pagination will not work.

So, the only way to solve my problem and still to use PromeFaces is to store ID in session?

[cagatay.civici]

You can still get it via requestparametermap, in paging request, it will be posted.

I know. But it is very bad and not pattern solution. Richfaces pagination allows such functionality

Is such design mean, that action method will not work also? For example, if I put commandButton in dataGrid.

CommandButton will work, as you can see in showcase. I couldn't understand your use-case, why do you ned that hiddeninput during pagination.
