Jsf Richfaces3.3.3 final Picklist example

JSP Code





Move control buttons without labels
<rich:pickList id="pickListId"  valueChangeListener="#{rolePermissionsBean.selectionChanged}" label="source List" title="pickList"
            immediate="true"
            value="#{rolePermissionsBean.selectedModuleList}" showButtonsLabel="false" listsHeight="150; width:239px;">
            <a4j:support event="picklistChanged" ajaxSingle="true" actionListener="#{rolePermissionsBean.listChanged}" >
                </a4j:support>
                <f:selectItems value="#{rolePermissionsBean.sourceModuleList}"/>
</rich:pickList>

Description Here,
1 : <rich:pickList id="pickListId"  valueChangeListener="#{rolePermissionsBean.selectionChanged}"
    value change listener will called when there is change in the pick list in left and right panel.

2 : value="#{rolePermissionsBean.selectedModuleList}" this indicate the pre selection of data in right panel

3 : <f:selectItems value="#{rolePermissionsBean.sourceModuleList}"/>  this indicates the Source list at left panel which can be move to right side .

4:   <a4j:support event="picklistChanged" ajaxSingle="true" actionListener="#{rolePermissionsBean.listChanged}" >  event to be called on selection.

5: Most important the Source and target (left and right)should be single list u should not define two list.
