OrderList Events

Due to popular community demand, we’ve added 3 events to OrderList component to bring the flexibility of callbacks. These are;

  • select
  • unselect
  • reorder

Usage is simple, in case you’d like to get notified whenever one of these events occur, hook-in via p:ajax;

<p:orderList value="#{orderListView.cities}" var="city" controlsLocation="none" itemLabel="#{city}" itemValue="#{city}">
<p:ajax event="select" listener="#{orderListView.onSelect}" update="msgs"/>
<p:ajax event="unselect" listener="#{orderListView.onUnselect}" update="msgs"/>
<p:ajax event="reorder" listener="#{orderListView.onReorder}" update="msgs"/>
</p:orderList>

public void onSelect(SelectEvent event) {
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Item Selected", event.getObject().toString()));
}
 
public void onUnselect(UnselectEvent event) {
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Item Unselected", event.getObject().toString()));
}
 
public void onReorder() {
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "List Reordered", null));
}

These events are coming soon for 5.1.5, check out the live demo to see it in action.

    Can we expect the same for PickList?
