Get rich:column sortBy working

jbossesblearner Nov 21, 2011 9:54 AM

Hello.

Using 4.0.0.Final, I don't get sortBy working. My xhtml file looks like:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<ui:composition xmlns="http://www.w3.org/1999/xhtml"

xmlns:h="http://java.sun.com/jsf/html"

xmlns:f="http://java.sun.com/jsf/core"

xmlns:ui="http://java.sun.com/jsf/facelets"

xmlns:a4j="http://richfaces.org/a4j"

xmlns:c="http://java.sun.com/jsp/jstl/core"

xmlns:rich="http://richfaces.org/rich">

<h:head/>

<h:body>

<f:view>

<h:form>

<rich:dataTable id="table" value="#{myBean.items}" var="item" rows="20"

rowKeyVar="row" rowClasses="normal, alternate">

<rich:column id="idCol" sortBy="#{item.id}">

<f:facet name="header">

<h:outputLabel value="id" />

</f:facet>

<h:outputText value="#{item.id}" id="id" />

</rich:column>

<rich:column id="secondCol" sortBy="#{item.second}">

<f:facet name="header">

<h:outputLabel value="second" />

</f:facet>

<h:outputText value="#{item.second}" id="second"/>

</rich:column>

</rich:dataTable>

</h:form>

</f:view>

</h:body>

</ui:composition>"

Any help is appreciated. Thank you.

since RF 4 you appearantly have to specify a sortOrder for each column in your bean.

Take a look into the example in the showcase:

http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=dataTable&sample=tableSorting&skin=blueSky

<rich:column sortBy="#{cap.name}" id="name"
                sortOrder="#{capitalsSortingBean.capitalsOrder}">
                <f:facet name="header">
                    <a4j:commandLink value="Sort by Capital Name" render="table"
                        action="#{capitalsSortingBean.sortByCapitals}" />
                </f:facet>
                <h:outputText value="#{cap.name}" />
            </rich:column>

and
private SortOrder capitalsOrder = SortOrder.unsorted;

a more generic example can be found under:

http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=dataTable&sample=arrangeableModel&skin=blueSky

This was a really quick answer. Thanks a lot. I will try to use sortOrder.

Hello.

I tried it like in the more generic example. The column header is a link now. When the link is clicked, the new sortOrder is set, then the sortOrder property is requested
but somehow the table isn't rerendered. Any ideas?

Hello.

Now it works. First it didn' work, because I didn't define comparators.

I have another question. Aren't the sort icons available anymore in richfaces 4.0.0.Final? I think they are nice, because with them you can see after wich column the table is sorted.
