---------------------------------

Could someone paste some code regarding how to get the current pageIndex.  Since I followed the example given, and I am not getting any value.  
I have defined my scroller in the following way:

<rich:datascroller  for="selCrsFceGrid" maxPages="10" page="#{courseSearch.scrollerPage}" immediate="true" >

 </rich:datascroller> 

and in the bean


private String scrollerPage = "";


public String getScrollerPage() {
		return scrollerPage;
	}

	public void setScrollerPage(String scrollerPage) {
		this.scrollerPage = scrollerPage;
	}

when I try to print the value of scrollerPAge

I get the following error:

page="#{courseSearch.scrollerPage}": java.lang.IllegalArgumentException: argument type mismatch
