    Example Of Selecting Rows In A Table

    Lee Theobald Newbie

      Hi all,

      I was wondering if someone could point me in the direction of a good example of selecting multiple items in a table using checkboxes.  The kind of thing that you see one applications like GMail (example screenshot).  You select a number of checkboxes in your table and then press an action like delete, move etc. to perform that action on those items.

      I've been looking around but haven't found a good example yet.  I'm just curious of the kind of backing bean structure people use for this kind of thing.

      Thanks for any info.

          Create a class to use for the row, give it a boolean field for the checkbox to bind to.

          Now you need to create a list of these and expose them to the front end.

          There are two ways, expose it through a factory method, @Unwrap or just have it as a List property a seam component. Don't just have the list as a property though, it will work but the performance is lousy because the seam interceptors will get called too many times.

          Now in you dataTable put in a column with a h:selectBooleanCheckbox and bind it to the boolean property on your row.

                 <rich:dataTable id="processNodesList" var="nodes" value="#{processNodesList.resultList}" 
                                   rendered="#{not empty processNodesList.resultList}" rowClasses="#{tableLnF.getRowSettings(skinBean.skin)}" 
                                   cellpadding="0" cellspacing="0" columns="3" columnClasses="formFont2">
                                <rich:column align="left" colspan="1">
                                    <f:facet name="header"><h:outputText style="text-align:left;" value="Select"></h:outputText></f:facet>
                                    <h:selectManyCheckbox value="#{userGroupHome.processName}">           
                                             <f:selectItem itemValue="#{nodes.name}"/>
                                <rich:column align="left" colspan="1">
                                    <f:facet name="header">Name</f:facet>
