t:datascroller cannot get past page 2

[Anders H. Andersen]

I have a datatable where the user can change the number of rows from
dropdownlist. The datatable should go back to page 1 when the number of
rows is changed. 

I am using the description on this page:
http://wiki.apache.org/myfaces/ManagingDataScrollerPage to control the
number of rows in the table and set the row index. I have a
valueChangeListener on the dropdownlist that sets the row index to zero.

The problem is that the datascroller will not scroll past page 2. The
rowindex is only incrementet from page 1 to page 2. Can annyone see
whats wrong?

The datatable looks like this:

<t:dataTable id="betalinger"
        value="#{betalingBB.alleUIBetalinger}" var="betalingUI"
        rendered="#{betalingBB.showBetalinger}"
        sortable="false" 
        rows="#{betalingBB.rowsPerPage}"

        rowIndexVar="rowIndex"
        first="#{betalingBB.rowIndex}">

Backing bean methods: 

        public void setRowsPerPage(int rowsPerPage) {
                this.rowsPerPage = rowsPerPage;
        }

        public int getRowsPerPage() {
                return this.rowsPerPage; 
        }

        public int getRowIndex() {
                return rowIndex;
        }

        public void setRowIndex(int rowIndex) {
                this.rowIndex = roundDownRowIndex(rowIndex);
                this.rowIndex = rowIndex;
        }

        private int roundDownRowIndex(int rowIndex) {
                int page = rowIndex / getRowsPerPage();
                return page * getRowsPerPage();
                
        }
        
        public void rowsPerPageChanged(ValueChangeEvent value) {
                // go to page 1
                setRowIndex(0); 
        }




Datascroller:

<t:dataScroller for="betalinger"

        pageCountVar="pageCount" pageIndexVar="pageIndex"

        paginator="true" paginatorMaxPages="10" 
        immediate="false"
        renderFacetsIfSinglePage="false"
        paginatorActiveColumnStyle="font-weight:bold;" >
        <f:facet name="first">
                <t:graphicImage url="/images/paging_begin.gif"
border="0" alt=""/>
        </f:facet>
        <f:facet name="last">
                <t:graphicImage url="/images/paging_end.gif" border="0"
alt=""/>
        </f:facet>
        <f:facet name="previous">
                <t:graphicImage url="/images/paging_left.gif" border="0"
alt=""/>
        </f:facet>
        <f:facet name="next">
                <t:graphicImage url="/images/paging_right.gif"
border="0" alt=""/>
        </f:facet>
</t:dataScroller>
