MULTISELECT in TableView

Hi,

I have a Table view with 'selectionMode = "MULTISELECT"'

<hbj:tableView id="SOTable"

model = "MyJCoBean.model1"

design = "ALTERNATING"

headerVisible = "true"

footerVisible = "true"

fillUpEmptyRows = "true"

navigationMode = "BYPAGE"

selectionMode = "MULTISELECT"

headerText = "Sales Order Details"

visibleRowCount= "5"

visibleFirstRow="<%=MyJCoBean.getVisibleFirstRow() %>"

onNavigate="Navigation">

</hbj:tableView>

I select the check box and click on navigation button to select other entries (using OnNavigate ) .. When I comeback again to the first page.. I dont see the 'checkbox' checked..

How do I store the state when I select the checkbox in TableView and Navigate for more selection..

Thanks,

EK
