    <p>In my application, I have a h:datatable which contains vehicles data and h:selectBooleanCheckBox in each of its row. I want know the selected checkbox in the datatable datatable's row in the backing bean without applying any submit button. The idea of doing this is; when any user clicks the check boxes in one application page, s/he could easily see the selected rows in other pages aswell beacause the datatable in every page contains many vehicles. Therefore, users could be able to see the selected vehicles in any page and do the related operation.</p> <p>The following shows part of my JSF page.</p> <pre><code>&lt;rich:dataTable id="vehicleTable" var="vhcl" value="#{mainPage.vehicleList}" binding="#{mainPage.vehicleTable}" &gt; &lt;rich:column id="col_sel" width="10px" &lt;h:selectBooleanCheckbox title="#{general.showOnMap}" onclick="showOnMap(this)" id="selectedCheckBox" /&gt; &lt;/rich:column&gt; &lt;rich:column id="trackId" label="#{general.vehicleName}" &gt; &lt;f:facet name="header"&gt; &lt;h:outputText value="#{general.vehicleName}" id="state_name" /&gt; &lt;/f:facet&gt; &lt;h:outputText value="#{vhcl.vehicle.mtsTrackId}" id="vehicleId" title="#{general.vehicleId}" style="font-size:10px; color:blue;" /&gt; &lt;br/&gt; &lt;h:outputText value="#{vhcl.vehicle.vehiclePlate}" id="vehiclePlate" title="#{general.licencePlate}" style="font-size:10px; color:blue"/&gt; &lt;/rich:column&gt; &lt;rich:column id="type_col" label="#{general.vehicleType}" &gt; &lt;f:facet name="header"&gt; &lt;h:outputText value="#{general.vehichleType}" id="vehichleTypeLabel" /&gt; &lt;/f:facet&gt; &lt;h:graphicImage value="#{vhcl.typeImage}" height="40" width="40" align="left"/&gt; &lt;h:panelGrid columns="1" align="right"&gt; &lt;h:graphicImage id="statusImage" value="#{vhcl.statusImage}" title="#{vhcl.status}" height="15" width="15" /&gt; &lt;h:graphicImage id="motorStatusImage" value="#{vhcl.motorStatusImage}" title="#{vhcl.motorStatus}" height="15" width="15" /&gt; &lt;/h:panelGrid&gt; &lt;/rich:column&gt; &lt;rich:column id="msg_col" label="#{general.lastMessageDate}" &gt; &lt;f:facet name="header"&gt; &lt;h:outputText value="#{general.lastMessageDate}" id="lastMsgDateLabel" /&gt; &lt;/f:facet&gt; &lt;h:outputText value="#{vhcl.messageDate}" id="lastMsgDate" /&gt; &lt;br /&gt; &lt;h:outputText value="Hız: " /&gt; &lt;h:outputText value="#{vhcl.instantSpeed}" id="lastSpeed" style="color:blue; font-weight:bold" /&gt; &lt;h:outputText value="km/s" /&gt; &lt;/rich:column&gt; &lt;rich:column id="addr_col" label="#{general.address}" &gt; &lt;f:facet name="header"&gt; &lt;h:outputText value="#{general.address}" id="addressLabel"/&gt; &lt;/f:facet&gt; &lt;h:outputText value="#{vhcl.address}" id="addr" /&gt; &lt;br /&gt; &lt;h:outputText value="#{vhcl.location}" id="location" style="color:blue;" /&gt; &lt;/rich:column&gt; </code></pre> <p></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
