dataScroller : invoke_app dataScroller.getPageIndex returns

[gonzalad]

Hello,

I'm using rich:dataScroller.

Datascroller updates the page number *after* INVOKE_APPLICATION phase is complete (or just after my action handler is called).

If I want to know the page number requested, I must use an actionListener (DataScrollerEvent.getNewScrolVal()), I cannot just rely on calling dataTable.getFirst() which returns the old value.

Is it a bug ?

See UIDataScroller code :

public void broadcast(FacesEvent event) throws AbortProcessingException {
 //-> this calls my actionHandler
 super.broadcast(event);
 //the pagination is here (should it be before my action handler ?
 if (event instanceof DataScrollerEvent) {
 DataScrollerEvent dataScrollerEvent = (DataScrollerEvent) event;
 setPage(dataScrollerEvent.getNewScrolVal());

 FacesContext context = FacesContext.getCurrentInstance();
 AjaxRendererUtils.addRegionByName(context, this, this.getId());
 AjaxRendererUtils.addRegionByName(context, this, this.getFor());

 setupReRender(context);

 MethodBinding scrollerListener = getScrollerListener();
 if (scrollerListener != null) {
 scrollerListener.invoke(context, new Object[]{event});
 }
 }
 }

For instance : when I paginate to page 2, the following code just prints the previous rendered page number.

I use the following code :

public String testScroll() {
 System.out.println(pageIndex="+getDataScroller().getPageIndex());
}

with

<rich:datascroller for="table"
 binding="#{reportAction.dataScroller}"
 action="#{reportAction.testScroll}" reRender="region"/>

Thanks for your insight !
