Hi Adnan,
I have corrected exactly the same scenario and "dataTable.setFirst(0)"
should definitely work.
Step 1: In ur Xhtml code do the binding for the scroller with ur managed
bean(CustomTreeNodePanel)
Eg:
<h:panelGrid columns="1" styleClass="scrollerTable2"
columnClasses="standardTable_ColumnCentered"
rendered="#{customTreeNodePanel.nodesCountToDisplay >
15}"> <!-- This 15 should be equal to the number of rows -->
<t:dataScroller id="scroll_1"
for="tree_data_models"
fastStep="5"
pageCountVar="pageCount"
pageIndexVar="pageIndex"
styleClass="scroller"
paginator="true"
paginatorMaxPages="7"
paginatorTableClass="paginator"
paginatorActiveColumnStyle="font-weight:bold;"
rendered="#{customTreeNodePanel != null}"
binding="#{customTreeNodePanel.scroll}">
Step 2: In managed bean define scroller and have getter setter
methods.(public)
Eg: private HtmlDataScroller scroll = new HtmlDataScroller();
Step 3 : Define method to reset scroll index
/**
* Resets the Scroller index to the given <code>index</code>
* @param index
*/
public void resetScrollerIndex(int index) {
if(getScroll() != null && getScroll().isPaginator()) {
getScroll().getUIData().setFirst(index);
}
}
Step 4: On second search call reset method resetScrollerIndex(0); with index
as zero.
This will definitely work :-). I had spent two days to fix this problem

Kiran Singh K
