Hi,
You can do this from 2 way.

First, you can use Jsf binding.

Second, you can manipulate the first attribute of datatable.

in this example datascroller always start from last page

 <rich:dataTable value="#{mybean.list}" var="var" id="testTable" rows="#{mybean.ROW_COUNT_OF_PAGING}" first="#{mybean.firsRowNumberOfDataTable}">

 private Integer ROW_COUNT_OF_PAGING=20;
 private Integer firsRowNumberOfDataTable;

 public void reRenderDataTable(){
 firsRowNumberOfDataTable=list.size() % ROW_COUNT_OF_PAGING==0 ?(list.size()<ROW_COUNT_OF_PAGING ? 0 :list.size()-ROW_COUNT_OF_PAGING):list.size()-(list.size() %ROW_COUNT_OF_PAGING);
 }

 public Integer getFirsRowNumberOfDataTable() {
 reRenderDataTable();
 return firsRowNumberOfDataTable;
 }

 public Integer getROW_COUNT_OF_PAGING() {
 return ROW_COUNT_OF_PAGING;
 }

I also try this function, But it can noly fix to page "2", whatever value you set on first. Is it Bugs?


Thanks
